NAME
tin, rtin - A Usenet newsreader

SYNOPSIS
tin [[-h|-H|-V] | [[[-a] [-dlnq|-Q] [-ArzxX]] [[-R|-S] -s News-dir] [-cuvZ] [-N|-M address] [-o|-w]] [-D debug_level] [-G article_limit] [-f newsrc_file] [-g server] [-m Mail_dir] [-p port] [-I index_dir] [newsgroup[,...]]]

DESCRIPTION
tin is a full-screen easy to use Usenet newsreader. It can read news locally (e.g., /var/spool/news) or remotely (rtin or tin -r option) via a NNTP (Network News Transport Protocol) server. It will automatically utilize NOV newsoverview(5) style index files if available locally or via the NNTP [X]OVER command (RFC2980).

tin has four separate levels of operation: Selection level, Group level, Thread level and Article level. Use the Help ('h') command to view a list of the commands available at a particular level.

On startup tin will show a list of the newsgroups found in ${TIN_HOMEDIR-"$HOME"}/.newsrc. An arrow '->' or highlighted bar will point to the first newsgroup. Move to a group by using the terminal arrow keys (terminal dependent) or Down ('j') and Up ('k'). Use PgUp/PgDn (terminal dependent) or PageUp ('^U') (CTRL-U) and PageDown ('^D') (CTRL-D) to page up/down. Enter a newsgroup by pressing '<CR>'.

The GroupNextUnreadArtOrGrp ('<TAB>') key enters the next newsgroup with unread articles.

EXIT STATUS
Interactive mode:

    0   Successful program execution.

    1   Usage, syntax, configuration file or network error.

Batch mode (''-Z''):

    0   No unread news

    1   Usage, syntax, configuration file or network error.

    2   Unread news

OPTIONS

-a  Toggle ANSI color (default is off).

-A  Force authentication on initial connect.

-c  Create/update index files for every group in ${TIN_HOMEDIR-"$HOME"}/.newsrc or file specified by the ''-f'' option and mark all articles as read.

-d  Don't load newsgroup descriptions (interactive mode).

-D debug-level
    Enter debug-level (1 = NNTP, 2 = all, 3 = newsrc, 4 = memory allocation).

-f file
    Use the specified file of subscribed to newsgroups in place of ${TIN_HOMEDIR-"$HOME"}/.newsrc.

-g server
    Use the server and newsrc specified in ${TIN_HOMEDIR-"$HOME"}/.tin/newsrctable.

-G article-limit
    Limit the number of articles/group to retrieve from the server.

-h  Help listing all command-line options.

-H  Brief introduction to tin that is also shown the first time it is started.

-I dir
    Directory in which to store newsgroup index files. Default is ${TIN_INDEX_NEWSDIR-"${TIN_HOMEDIR-"$HOME"}/.tin"}/.news. This option has no effect if tin retrieves its index files via NNTP and cache_overview_files is turned off.

-l  Get number of articles per group from the ${TIN_LIBDIR-NEWSLIBDIR}"/"${TIN_ACTIVEFILE-active} file. If reading via NNTP this is done with the LIST command (RFC977). This might result in incorrect article counts but is usually faster than the default which is to read the ${TIN_LIBDIR-NEWSLIBDIR}"/"${TIN_ACTIVEFILE-active} file (either directly or via LIST) and then check the article count via NNTP GROUP command (RFC977) ''-ln''.

-m dir
    Mailbox directory to use. Default is ${TIN_HOMEDIR-"$HOME"}/Mail.

-M user
    Mail unread articles to specified user for later reading. For more information read section "AUTOMATIC MAILING AND SAVING NEW NEWS".

-n  Only load groups from the ${TIN_LIBDIR-NEWSLIBDIR}"/"${TIN_ACTIVEFILE-active} file that are subscribed to in the user's ${TIN_HOMEDIR-"$HOME"}/.newsrc. This allows a noticeable speedup when connecting via a slow line, but tin can not tell which groups are moderated. See also ''-l''.

-N  Mail unread articles to yourself for later reading. For more information read section "AUTOMATIC MAILING AND SAVING NEW NEWS".

-o  Quick post all postponed articles and exit. In order for this to be really quick, it should be used with ''-n'' if possible.

-p port
    Port to use if reading via NNTP (default is 119). This also overrides the environment variable $NNTPPORT if set.

-q  Don't check for new newsgroups.

-Q  Quick start. Start tin as quickly as possible. Currently this is equivalent to ''-nqd''.

-r  Read news remotely from the default NNTP server specified in the environment variable $NNTPSERVER or contained in the file /etc/nntpserver.

-R  Read news saved by the ''-S'' option.

-s dir
    Save/read articles to/in directory. Default is ${TIN_HOMEDIR-"$HOME"}/News.

-S  Save unread articles for later reading by the ''-R'' option. For more information read section "AUTOMATIC MAILING AND SAVING NEW NEWS".

-u  Create/update index files for every group in ${TIN_HOMEDIR-"$HOME"}/.newsrc or file specified by the ''-f'' option. This option is disabled if tin retrieves its index files via a NNTP server and cache_overview_files is turned off.

-v  Verbose mode for ''-c'', ''-M'', ''-N'', ''-S'', ''-u'' and ''-Z'' options.

-V  Print version and date information.

-w  Quick mode to post an article and then exit. In order for this to be really quick, it should be used with ''-n'' if possible.

-x  No posting mode. You cannot post articles if you use this option.

-X  No overwrite mode. ${TIN_HOMEDIR-"$HOME"}/.newsrc and files in ${TIN_HOMEDIR-"$HOME"}/.tin will not be overwritten but may be created if they don't exist.

-z  Only start tin if there is any new/unread news. If there is news tin will position cursor at first group with unread news. Useful for putting in login file.

-Z  Check if there is any new/unread news and exit with appropriate status. If ''-v'' option is specified the number of unread articles in each group is printed. An exit code 0 indicates no news, 1 that an error occurred and 2 that new/unread news exists. Useful for writing scripts.

tin can also dynamically change its options by the OptionMenu ('M') command. Any changes are written to ${TIN_HOMEDIR-"$HOME"}/.tin/tinrc. For more information see section "GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES" and tin(5).

A list of groups can be specified after the other command-line options. This can be useful if you wish to yank in or subscribe to a hand-picked subset of the active newsgroups. See the section "NEWSGROUP LISTS & WILDCARDS" for the types of pattern that tin understands.

If you specify a single group-name, or a wildcard that matches a single group, then you will automatically enter that group. Otherwise the normal group selection screen will appear, but with all the matching groups present too, as though you had yanked just those groups in.

Once you use SelectYankActive ('y') to yank in all active groups, or SelectToggleReadDisplay ('r') to toggle the read/unread status, then the command-line groups will be gone. You can use SelectSyncWithActive ('Y') to reread the ${TIN_LIBDIR-NEWSLIBDIR}"/"${TIN_ACTIVEFILE-active} file and get them back.

NB: With the ''-n'' flag, only unsubscribed groups in the ${TIN_HOMEDIR-"$HOME"}/.newsrc file (or the newsrc-file given by the ''-f'' command-line switch or via ${TIN_HOMEDIR-"$HOME"}/.tin/newsrctable) can be matched.

USAGE

  NEWS ADMINISTRATION
Maintaining Netnews on large networks of machines can be a pretty time consuming job as I discovered when I was given the job of maintaining our news system and news users.

A user starting tin for the first time can be automatically subscribed to a list of newsgroups that are deemed appropriate by the news administrator. The subscriptions file should be created in your news lib directory (i.e., ${TIN_LIBDIR-NEWSLIBDIR}/subscriptions) and should have file permissions set to 0644. If you read news via NNTP, then your news server must support the LIST SUBSCRIPTIONS command. It is part of the Common NNTP Extensions (RFC2980) and all modern servers should understand it.

  SCREEN FORMAT
tin has four separate levels of operation: Selection level, Group level, Thread level and Article level.

At the Selection level the title displays (the name of the newsserver and) the number of subscribed groups (containing new unread articles). The newsgroups are displayed in the middle of the screen with the number of unread articles displayed on the same line in front.

->M    1     2  comp.security.announce  Announcements from the CERT abou
  M    2     1  news.admin.announce     Announcements for news adminstra
       3    22  news.software.misc      News-related software other than
       4  1475  news.software.nntp      The Network News Transfer Protoc
  X    5   124  news.software.readers   Discussion of software used to r

There may also be a character prefixing the line. An explanation follows:

u   This group is unsubscribed. To see only your subscribed groups use the SelectToggleReadDisplay ('r') or SelectYankActive ('y') toggle keys.

M   This is a moderated group. Any posts you make will have to be approved by the group administrator before it will be made public. tin will ask for confirmation before you post to a moderated group.

N   This is a new newsgroup which has been created since you last used tin. New newsgroups are not subscribed to by default (However, see the $AUTOSUBSCRIBE / $AUTOUNSUBSCRIBE environment variables). Subscribe to it in the normal way if you wish the group to continue to appear in your Selection Menu. Simply ignore new newsgroups and they will be gone the next time you start tin. You will have to yank in all the groups to find them in a later session.

D   This group no longer exists. If you no longer wish to see this group then unsubscribe from it in the normal way. This flag will only appear if you have set strip_bogus to "ask" in the Options Menu.

X   You may no longer make posts to this group. Often a group will be superseded by a more appropriately named one.

=   This group has been renamed and you may no longer post to it. If you do, then you will receive an error from your newsserver telling you the correct group to post to.

At the Group level the title contains the name of the group, the number of conversation threads, the threading method, the limit of articles to get, the total number of articles, the number of hot articles, the number of recent articles and the number of killed articles. I.e.:

            alt.sources (5B -50/23+ 0* 3o 0K).

The characters after the numbers are depending to the configuration and if your are in show_only_unread_arts mode or not. Some numbers could be missing if the specific option is not enabled. It might also contain an 'M', 'X' or '=' (see above; doesn't work with the ''-n'' command-line switch!) if the group is moderated, set to no posting or postings to it get redirected.

If a thread has unread articles in it it's marked with a art_marked_unread in front of the total number of articles in the thread. If there are recent articles within the thread it might be marked with art_marked_recent in front of the total number of articles in the thread - this is controlled by the recent_time option. If a thread has hot articles in it (see also section "FILTERING ARTICLES") it's marked with art_marked_selected in front of the total number of articles in the thread. The number of lines of the first (unread) article in the thread might also be shown right before the subject - this is controlled by the show_info option.

At the Thread level the screen usually (depends on the threading method used) looks like this:

  COMMON EDITING COMMANDS
An emacs style editing package allows the easy editing of input strings. An history list allows the easy reuse of previously entered strings. In addition to the cursor keys, the following commands are available when editing a string:

^A, ^E
    move to beginning or end of line, respectively.

^F, ^B
    non-destructive move forward or back one location, respectively.

^D  delete the character currently under the cursor, or send EOF if no characters in the buffer.

^H, <DEL>
    delete character left of the cursor.

^K  delete from cursor to end of line.

^P, ^N
    move through history, previous and next, respectively.

^L, ^R
    redraw the current line.

<CR>
    places line on history list if non-blank, appends newline and returns to the caller.

<ESC>
    aborts the present editing operation.

  GLOBAL COMMANDS
The following commands are available at all 4 menu levels and always have the same effect.

ShellEscape '!'
    Shell escape. ShellEscape by itself will launch a shell, ShellEscape <command> will run an external <command>. This facility may have been disabled by the System Administrator.

  GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES
At startup, tin reads in the configuration files (see also tin(5)). They contain a list of variables that can be used to configure the way tin works. If it exists, the global configuration file, ${TIN_LIBDIR-NEWSLIBDIR}/tinrc is read. After that, the user's own configuration file is read from ${TIN_HOMEDIR-"$HOME"}/.tin/tinrc. The global file is useful for distributing system-wide defaults to new users who have no private tinrc yet.

The variables are user configurable by editing ${TIN_HOMEDIR-"$HOME"}/.tin/tinrc directly. Most of them can also be set in the GLOBAL OPTIONS MENU which is accessed by pressing OptionMenu ('M') at all levels. It allows the user to customize the behavior of tin. The options are saved to the file ${TIN_HOMEDIR-"$HOME"}/.tin/tinrc when you exit tin so don't edit the file directly whilst tin is running.

In the options menu use the cursor keys in the usual way to move around. Use ConfigSelect ('^J' or '<CR>') to 'open' the option you wish to change. You will need to enter a new value or use '<SPACE>' to toggle the available options. ConfigSelect will save the new value, '<ESC>' will abort without saving changes.

As with the other menus, RedrawScr ('^L') will redraw the screen. You can use SearchSubjF ('/'), SearchSubjB ('?') and SearchRepeat ('\') to search for a specific option. Use Quit ('q') to exit the option menu and keep your changes. Use QuitTin ('Q') to exit without keeping your changes.

Here is a full list of all the available variables. The name in braces is the name of the corresponding setting in ${TIN_HOMEDIR-"$HOME"}/.tin/tinrc.

If set to 'Yes' then sections of uuencoded data will be shown with a single tag line showing the size and filename (much the same as a MIME attachment). If set to 'Hide all' then any line that looks like uuencoded data will be folded into a tag line. This is useful when uuencoded data is split across more than one article but can also lead to false positives. This setting can also be toggled in the article viewer. Default is 'No'.

External inews (inews_prog)
    Path, name and options of external inews(1). If you are reading via NNTP the default value is --internal (use built-in NNTP inews), else it is "inews -h". The article is passed to inews_prog on STDIN via '< article'.

(info_in_last_line)
    If ON, show current group description or article subject in the last line (not in the pager and global menu) - ToggleInfoLastLine ('i') toggles setting. This facility is useful as the full width of the screen is available to display long subjects. Default is OFF.

    Interactive mailreader: if greater than 0 your mailreader will be invoked earlier for reply so you can use more of its features (e.g. MIME, pgp, ...). 1 means include headers, 2 means don't include headers (old use_mailreader_i=ON option). 0 turns off usage. This option has to suit default_mailer_format. Default is 0.

Use inverse video for page headers (inverse_okay)
    If ON use inverse video for page headers and URL highlighting. Default is ON.

Keep failed arts in ~/dead.articles (keep_dead_articles)
    If ON keep all failed postings in ${TIN_HOMEDIR-"$HOME"}/dead.articles besides keeping the last failed posting in ${TIN_HOMEDIR-"$HOME"}/dead.article. Default is ON.

Filter which articles (kill_level)
    This option controls the processing and display of articles that are killed. There are 3 options:

    0   Kill only unread arts is the 'traditional' behavior of tin. Only unread articles are killed once only by marking them read. As filtering only happens on unread articles with kill_level set to 0, art_marked_killed and art_marked_read_selected are only shown once. When you reenter the group the mark will be gone.

    1   Kill all arts & show with K will process all articles in the group and therefore there is a processing overhead when using this option. Killed articles are threaded as normal but they will be marked with art_marked_killed.

    2   Kill all arts and never show will process all articles in the group and therefore there is a processing overhead when using this option. Killed articles simply does not get displayed at all.
Default is 0 (Kill only unread arts).

Use 8bit characters in mail headers (mail_8bit_header)
    Allows 8bit characters unencoded in the header of mail message. Default is OFF. Turning it ON is effective only if mail_mime_encoding is also set to 8bit. Leaving it OFF is safe for most users and compliant to Internet Mail Standard (RFC2822 and RFC2047). Default is OFF.

Mail address (mail_address)
    User's mail address (and full name), if not username@host. This is used when creating articles, sending mail and when pgp(1) signing.

MIME encoding in mail messages (mail_mime_encoding)
    MIME encoding of the body in mail message, if necessary (8bit, base64, quoted-printable, 7bit) Default is 8bit and no encoding (or charset conversion) is performed (i.e., local charset is used as it is).

Quote line when mailing (mail_quote_format)
    Format of quote line when replying (via mail) to an article (%A=Address, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is "In article %M you wrote:"

Format of the mailbox (mailbox_format)
    Select one of the following mailbox-formats: MBOXO (default, except for SCO), MBOXRD or MMDF (default on SCO). See mbox(5) for more details on MBOXO and MBOXRD and mmdf(5) for more details about MMDF.

'Mark article read' ignores tags (mark_ignore_tags)
    When this is ON, the GroupMarkThdRead, ThreadMarkArtRead functions ('K') mark just the current article or thread, ignoring other tagged, unread articles. When OFF, the same function presents a menu with choices of the current thread or article, all tagged, unread articles, or nothing.

Mark saved articles/threads as read (mark_saved_read)
    If ON mark articles that are saved as read. Default is ON.

Viewer program for MIME articles (metamail_prog)
    Path, name and options of external metamail(1) program used to view non-textual parts of articles. To use the built-in viewer, set to --internal. This is the default value when metamail(1) is not installed. Leave it blank if you don't want any automatic viewing of non-textual attachments. The 'V' command can always be used to manually view any attachments. See also ask_for_metamail.

MM_CHARSET (mm_charset)
    Charset supported locally, which is also used for MIME header (charset parameter and charset name in header encoding) in mail and news postings. If MIME_STRICT_CHARSET is defined at compile time, text in charset other than the value of this parameter is considered not displayable and represented as '?'. Otherwise, all character sets are regarded as compatible with the display. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined. If your system supports iconv(3), this option is disabled and you should use mm_network_charset instead.

MM_NETWORK_CHARSET (mm_network_charset)
    Charset used for posting and MIME headers; replaces mm_charset. Conversion between mm_network_charset and local charset (determined via nl_langinfo(3)) is done via iconv(3), if this function is not available on your system this option is disabled and you have to use mm_charset instead. mm_network_charset is limited to one of the following charsets:
    US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU} EUC-{CN,JP,KR,TW}, ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
    Not all values might work on your system, see iconv_open(3) for more details. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined.

Attribute of highlighting with _dash_ (mono_markdash)
    Character attribute of words emphasized like _this_. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

Attribute of highlighting with /slash/ (mono_markslash)
    Character attribute of words emphasized like /this/. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

Attribute of highlighting with *stars* (mono_markstar)
    Character attribute of words emphasized like *this*. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

Attribute of highlighting with -stroke- (mono_markstroke)
    Character attribute of words emphasized like -this-. It depends on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

(newnews)
    These are internal timers used by tin to keep track of new newsgroups. Do not change them unless you understand what they are for.

Display these header fields (or *) (news_headers_to_display)
    Which news headers you wish to see. If you want to see _all_ the headers, place an '*' as this value. This is the only way a wildcard can be used. If you enter 'X-' as the value, you will see all headers beginning with 'X-' (like X-Alan or X-Pape). You can list more than one by delimiting with spaces. Not defining anything turns off this option.

Do not display these header fields (news_headers_to_not_display)
    Same as news_headers_to_display except it denotes the opposite. An example of using both options might be if you thought X- headers were A Good Thing(tm), but thought Alan and Pape were miscreants... well then you would do something like this: news_headers_to_display=X- news_headers_to_not_display=X-Alan X-Pape. Not defining anything turns off this option.

Quote line when following up (news_quote_format)
    Format of quote line when posting/following up an article (%A=Address, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is "%F wrote:".

    2   NFKD: Compatibility Decomposition

    3   NFC: Canonical Decomposition, followed by Canonical Composition

    4   NFD: Canonical Decomposition
Some normalization modes are only available if they are supported by the library tin uses to do the normalization. Default is NFKC.

PgDn goes to next unread article (pgdn_goto_next)
    If ON the Page Down keys will go to the next unread article when pressed at the end of a message. Default is ON.

Goto first unread article in group (pos_first_unread)
    If ON put cursor at first unread article in group otherwise at last article. Default is ON.

Use 8bit characters in news headers (post_8bit_header)
    Allows 8bit characters unencoded in the header of a news article, if set this also disables the generation of MIME-headers when they are usualy required. Default is OFF. Only enacted if post_mime_encoding is also set to 8bit. In a number of local hierarchies where 8bit characters are used, using unencoded (raw) 8bit characters in header is acceptable and sometimes even recommended so that you need to check the convention adopted in the local hierarchy of your interest to determine what to do with this and post_mime_encoding.

MIME encoding in news messages (post_mime_encoding)
    MIME encoding of the body in news message, if necessary. (8bit, base64, quoted-printable, 7bit) Default is 8bit, which leads to no encoding. base64 and quoted-printable are usually undesired on usenet.

Quoting behavior (quote_style)
    How articles should be quoted when following up or replying to them. There are a number of things that can be done: empty lines can be quoted, signatures can be quoted and quote_chars can be compressed when quoting multiple times (for example, '> > >' will be turned into '>>>'). The default is to compress quotes, and to quote empty lines.
    When you are viewing an article in raw mode ('^H'), and follow up or reply to it, the signature will be quoted even if it would otherwise not be.

Regex used to show quoted lines (quote_regex)

    If set to 0, this feature is deactivated, otherwise it means the number of days. Default is 2.

Render BiDi (render_bidi)
    If ON tin does the rendering of bi-directional text. If OFF tin leaves the rendering of bi-directional text to the terminal. Default is OFF.

Interval in seconds to reread active (reread_active_file_secs)
    The news ${TIN_LIBDIR-NEWSLIBDIR}"/"${TIN_ACTIVEFILE-active} file is reread at regular intervals to show if any new news has arrived. Default is 1200. Setting this to 0 will disable this feature.

    If the score of an article is below or equal this value the article gets marked as killed.

Score limit (select) (score_limit_select)
    If the score of an article is above or equal this value the article gets marked as hot.

Default score to kill articles (score_kill)
    Score of an article which should be killed, this must be <= score_limit_kill.

Default score to select articles (score_select)
    Score of an article which should be marked hot, this must be >= score_limit_select.

Number of lines to scroll in pager (scroll_lines)
    The number of lines that will be scrolled up/down in the article pager when using cursor-up/down. The default is 1 (line-by-line). Set to 0 to get traditional tin page-by-page scrolling. Set to -1 to get page-by-page scrolling where the top/bottom line is carried over onto the next page. This setting supersedes show_last_line_prev_page=ON. Set to -2 to get half-page scrolling. This setting supersedes full_page_scroll=OFF.

    1   Address, ''Subject:'' line & the address part of the ''From:'' line are displayed.

    2   Full Name, ''Subject:'' line & the authors full name part of the ''From:'' line are displayed (default).

    3   Address and Name, ''Subject:'' line & all of the ''From:'' line are displayed.

Show description of each newsgroup (show_description)
    If ON show a short group description text after newsgroup name at the group selection level. The ''-d'' command-line flag will override the setting and turn descriptions off. The text used is taken from the ${TIN_LIBDIR-NEWSLIBDIR}/newsgroups file and if supported (requires tin to be build with mh-mail-handling support) from ${TIN_HOMEDIR-"$HOME"}/.tin/mailgroups for mailgroups. Default is ON.

Show lines/score in listings (show_info)
    Which information about the thread or article should be shown. Default is 1, show only the line count.

Regex used to highlight /slashes/ (slashes_regex)
    A regular expression that will be applied when reading articles. All matching words are shown in col_markslash or mono_markslash. If slashes_regex is blank, then tin uses a built-in default.

Sort articles by (sort_article_type)
    This specifies how articles should be sorted. Sort by ascending Date (6) is the default. The following sort types are allowed:

    0   Nothing, don't sort articles.

    1   Subject: (descending), sort articles by ''Subject:'' field descending.

    2   Subject: (ascending), sort articles by ''Subject:'' field ascending.

    spam,delete,remove

Space goes to next unread article (space_goto_next_unread)
    <SPACE> normally acts as a Page Down key and has no effect at the end of an article. If this option is turned ON the <SPACE> command will go to the next unread article when the end of the article is reached (rn-style pager). Default is OFF.

Regex used to highlight *stars* (stars_regex)
    A regular expression that will be applied when reading articles. All matching words are shown in col_markstar or mono_markstar. If stars_regex is blank, then tin uses a built-in default.

Start editor with line offset (start_editor_offset)
    Set ON if the editor used for posting, follow-ups and bug reports has the capability of starting and positioning the cursor at a specified line within a file. Default is ON.

Strip blanks of end of lines (strip_blanks)
    Strips the blanks from the end of each line therefore speeding up the display when reading on a slow terminal or via modem. Default is ON.

Remove bogus groups from newsrc (strip_bogus)
    Bogus groups are groups that are present in your ${TIN_HOMEDIR-"$HOME"}/.newsrc file that no longer exist on the news server. There are 3 options. 0 means do nothing & always keep bogus groups. 1 means bogus groups will be permanently removed. 2 means that bogus groups will appear on the Group Selection Menu, prefixed with a 'D'. This allows you to unsubscribe from them as and when you wish. Default is 0 (Always Keep).

No unsubscribed groups in newsrc (strip_newsrc)
    If ON, then unsubscribed groups will be permanently removed from your ${TIN_HOMEDIR-"$HOME"}/.newsrc file. Default is OFF.

Regex used to highlight -strokes- (strokes_regex)
    A regular expression that will be applied when reading articles. All matching words are shown in col_markstroke or mono_markstroke. If strokes_regex is blank, then tin uses a built-in default.

Tab goes to next unread article (tab_goto_next_unread)
    If enabled pressing PageNextUnread ('<TAB>') at the Article level will go to the next unread article immediately instead of first paging through the current one. Default is ON.

Wrap around threads on next unread (wrap_on_next_unread)
    If enabled a search for the next unread article will wrap around all articles to find also previous unread articles. If disabled the search stops at the end of the thread list. Default is ON.

Display "a as Umlaut-a (tex2iso_conv)
    If ON, show "a as Umlaut-a, etc. Default is OFF. This behavior can also be toggled in the article viewer via PageToggleTex2iso ('"').

Thread articles by (thread_articles)
    Defines which threading method to use. It's possible to set the threading type on a per group basis by setting the group attribute variable thread_arts to 0 - 4 in the file ${TIN_HOMEDIR-"$HOME"}/.tin/attributes. (See also "GROUP ATTRIBUTES".) The default is Both Subject and References. The choices are:

    0   None, don't thread.

    1   Subject, thread on ''Subject:'' only.

    2   References, thread on ''References:'' only.

    3   Both Subject and References, thread on ''References:'' then ''Subject:'' (default).

    4   Multipart Subject, thread multipart articles on ''Subject:''.

    5   Percentage Match, thread base upon a partial character match on ''Subject:''.

Catchup thread by using left key (thread_catchup_on_exit)
    If ON catchup group/thread when leaving with the left arrow key. Default is ON.

Matchingness of a thread (thread_perc)
    How closely the subjects must match for two threads to be considered part of the same thread. This is a percentage and the default if 75%.

Score of a thread (thread_score)
    How the total score of a thread is computed. Default is 0, the maximum score in this thread.

    0   Max, the maximum score in this thread.

    1   Sum, the sum of all scores in this thread.

    2   Average, the average score in this thread.

Transliteration (translit)
    If ON append //TRANSLIT to the first argument of iconv_open(3) to enable transliteration. This means that when a character cannot be represented in the target character set, it can be approximated through one or several similarly looking characters. On systems where this extension doesn't exist, this option is disabled. Default is OFF.

Regex used to highlight _underline_ (underscores_regex)
    A regular expression that will be applied when reading articles. All matching words are shown in col_markdash or mono_markdash. If underscores_regex is blank, then tin uses a built-in default.

Remove ~/.article after posting (unlink_article)
    If ON remove ~/.article after posting. Default is ON.

Program that opens URL's (url_handler)
    The program that will be run when launching URL's in the article viewer using PageViewUrl ('U'). The actual URL will be appended to this. Default is url_handler.sh %s.

URL highlighting in message body (url_highlight)
    Enable highlighting URLs in message body. Default is ON.

Use ANSI color (use_color)
    If enabled tin uses ANSI-colors. Default is OFF.

Use scroll keys on keypad (use_keypad)
    Default is OFF.

Use mouse in xterm (use_mouse)
    Allows the mouse key support in a xterm(1x) to be enabled/disabled. Default is OFF.

Use slrnface to show ''X-Face:''s (use_slrnface)
    If enabled tin uses slrnface(1) to interpret the ''X-Face:'' header. For this option to have any effect, tin must be running in an xterm(1x) and slrnface(1) must be in your $PATH. Default is OFF.

Wildcard matching (wildcard)
    Allows you to select how tin matches strings. The default is 0 and uses the wildmat notation, which is how this has traditionally been handled. Setting this to 1 allows you to use perl(1) compatible regular expressions pcre(3) (see also perlre(1) and pcrepattern(3)). You will probably want to update your filter file if you use this regularly. NB: Newsgroup names will always be matched using the wildmat notation.

What to display instead of mark (word_h_display_marks)
    Should the leading and ending stars, slashes, strokes and dashes also be displayed, even when they are highlighting marks?

    0   no

    1   yes, display mark

    2   print a space instead

Word highlighting in message body (word_highlight)
    Enable word highlighting. See word_h_display_marks for the options available. If use_color is enabled the colors specified in col_markdash, col_markslash, col_markstar and col_markstroke are used for word highlighting else the character attributes specified in mono_markdash, mono_markslash, mono_markstar and mono_markstroke are used. Default is ON.

Page line wrap column (wrap_column)
    Sets the column at which a displayed article body should be wrapped. If this value is equal to 0, it defaults to the current screen width. If this value is greater than your current screen width the part off-screen is not displayed. Thus setting this option to a large value can be used to disable wrapping. If this value is negative the wrap margin is the current screen width plus the given value (as long as the result is still positive, otherwise it will fall back to the current screen width). Default is 0, wrapping at the current screen width.

Quote line when cross-posting (xpost_quote_format)
    Format is the same as for news_quote_format, this is used when answering to a crossposting to several groups with no ''Followup-To:'' set.

  GROUP ATTRIBUTES
tin allows certain attributes to be set on a per group basis. If it exists, the global attributes file, ${TIN_LIBDIR-NEWSLIBDIR}/attributes is read. After that, the user's own attributes file ${TIN_HOMEDIR-"$HOME"}/.tin/attributes is read. The global attributes file is useful for distributing system-wide defaults to new users who have no private attributes file yet. A later version will provide a menu interface to set all the attributes. At present you will have to edit the file with your editor.

Note that the scope=<grouplist> line has to be specified before the attributes are specified for that list. All attributes are set to a reasonable default so you only have to specify the attribute that you want to change (e.g., savedir). All toggle attributes are set by specifying ON/OFF. Otherwise, these function exactly the same as their global equivalents. For more details see tin(5).

  FILTERING ARTICLES
When there is a subject or an author which you are either very interested in, or find completely uninteresting, you can easily instruct tin to auto-select or auto-kill articles that match rules that you specify. This can be anything from the name of the author to the number of lines in an article.

When tin starts up the user's kill-file ${TIN_HOMEDIR-"$HOME"}/.tin/filter (see also tin(5)) is read. Each time a newsgroup is entered the rules are applied and articles killed or selected when they meet certain criteria.

The degree to which rules are applied depend on the kill_level tinrc setting. By default killed articles will only be marked read. Adjust kill_level for more aggressive processing. Articles that match an auto-selection rule are marked with a ''*''.

Filtering rules can be manually entered into ${TIN_HOMEDIR-"$HOME"}/.tin/filter (but don't do this whilst running tin else you will lose your changes) or by using an on-screen menu within tin.

The filtering capabilities of tin have been significantly enhanced over previous versions to include scoring and better pattern matching. It is recommended that you read the file filtering in the tin documentation directory.

The on-screen filtering menu is accessed by pressing '^K' at the Group and Article levels. It allows the user to kill or select an article that matches the current ''Subject:'' line, ''From:'' line or a string entered by the user. The user entered string can be applied to the ''Subject:'' or ''From:'' lines of an article. The kill description can be limited to the current newsgroup or it can apply to all newsgroups. Once entered the user can abort the command and not save the kill description, edit the kill file or save the kill description.

  POSTING ARTICLES
tin allows posting of articles, follow-up to already posted articles and replying direct through mail to the author of an article.

Use the Post ('w') command to post an article to a newsgroup. After entering the post subject the default editor (i.e., vi(1)) or the editor specified by the $VISUAL or $EDITOR environment variable will be started and the article can be entered. To crosspost articles simply add a comma and the name of the newsgroup(s) to the end of the ''Newsgroups:'' line at the beginning of the article. After saving and exiting the editor you are asked if you wish to a)bort posting the article, e)dit the article again or p)ost the article to the specified newsgroup(s).

Use the DisplayPostHist ('W') command to display a history of the articles you have posted. The date the article was posted, which newsgroups the article was posted to and the articles subject line are displayed.

Use the PageFollowupQuote ('f'), PageFollowup ('F') or PageFollowupQuoteHeaders ('^W') command to post a follow-up article to an already posted article. The PageFollowupQuote command will copy the text of the original article into the editor. The PageFollowupQuoteHeaders command will copy the text and all headers of the original article into the editor. The editing procedure is the same as when posting an article with the Post ('w') command.

Use the PageReplyQuote ('r'), PageReply ('R') or PageReplyQuoteHeaders ('^E') command to reply direct through mail to the author of an already posted article. The PageReplyQuote command will copy the text of the original article into the editor. The PageReplyQuoteHeaders command will copy the text and all headers of the original article into the editor. The editing procedure is the same as when posting an article with the Post ('w') command. After saving and exiting the editor you are asked if you wish to abort sending the article via PostAbort ('a'), edit the article again via PostEdit ('e') or send the article to the author via PostSend ('s').

  CUSTOMIZING THE ARTICLE QUOTE STRING
When posting a followup to an article or replying direct to the author of an article via email the text of the article can be quoted. The beginning of the quoted text can contain information about the quoted article (e.g., Name and the Message-ID of the article). To allow for different situations certain information from the article can be used in the quoted string. The following variables are expanded if found in the tinrc variables mail_quote_format, news_quote_format or xpost_quote_format:
    %A	Address (Email)
    %D	Date
    %F	Full address (%N <%A>)
    %G	Groupname
    %M	Message-ID
    %N	Fullname of author
    %C	Firstname of author
    %I	Initials of author
e.g.,
    mail_quote_format=On %D in %G you wrote:
    news_quote_format=In %M, %F wrote:
would expand to:
    On 21 Sep 1993 09:45:51 -0400 in alt.sources you wrote:
    In <abcINN123@example.org>, Joe Bar <joe@example.org> wrote:
The quoted text section of an article is marked by a preceding quote string at the beginning of each quoted line. The default quote string is set to '>_'. The default can be changed by setting the tinrc variable quote_chars to ones own preference. (Note that '_' underline is used to represent a space).

  MAILING PIPING PRINTING REPOSTING AND SAVING ARTICLES
The command interface to GroupMail, PageMail, PostMail or ThreadMail ('m'), Pipe ('|'), Print ('o'), PageRepost or GroupRepost ('x') and GroupSave, PageSave or ThreadSave ('s' and GroupAutoSave, PageAutoSave or ThreadAutoSave 'S') articles is the same for ease of use.

Auto-saving with *AutoSave ('S') is a special case and operates only on marked articles. They will processed without any further prompting according to the default save parameters defined in tinrc or by any attributes set for the current group.

Otherwise, the initial prompt will ask you to select which article, thread, hot (auto-selected), regex pattern, tagged articles you wish to mail, pipe etc.

Tagged articles must have already been tagged with a *Tag ('t') command. All tagged articles can be untagged by a *Untag ('U') untag command.

If a regex pattern is selected you are asked to enter a pattern (e.g., to match all articles subject lines containing 'net News' you enter "net News"). Any articles that match the entered expression will be mailed, piped etc. See also the wildcard tinrc variable for advanced pattern matching options.

Various expansion characters are recognized when entering the directory and file to save to. Environment variables (prefixed with '$') and user home directories (prefixed by '~' or '~username') can be specified. Environment variables can themselves contain other special characters.

To save articles to a mailbox enter '=<mailbox name>' when asked for the save filename. If you enter just '=' then articles will be saved to a mailbox with the name of the current newsgroup (eg, alt.sources). See default_maildir.

To save in savedir/<news.group.name>/<filename> format enter '+<filename>'. Environment variables are allowed within a filename (e.g., $SOURCES/dir/filename). See default_savedir.

When saving articles you can specify whether the saved files should be post processed. A default process type can be set via post_process_type.

  AUTOMATIC MAILING AND SAVING NEW NEWS
tin allows new/unread news articles to be mailed (''-M'' and ''-N'' option) or saved (''-S'' option) in batch mode for later reading. Useful when going on holiday and you don't want to return and find that expire has removed a whole load of unread articles. Best to run via cron(1) everyday while away, after which you will be mailed a report of which articles were mailed/saved from which newsgroups and the total number of articles mailed/saved. Articles are saved in a private news structure under your <savedir> directory (default is ${TIN_HOMEDIR-"$HOME"}/News). Be careful of using this option if you read a lot of groups because you could overflow your file system.

If you only want to save some of your groups use the batch_save tinrc variable. Set to ON or OFF in tinrc to enable/disable saving of all groups and then use the batch_save attribute to fine tune which groups you want to have saved. For example, if you want to save most of your groups, then set batch_save to ON in tinrc and selectively turn off the ones you don't want using attributes.

tin -M iain -c -f newsrc.mail
    (mail any unread articles in newsgroups specified in file newsrc.mail to the local user iain and mark them as read)

tin -S -c -f newsrc.save
    (save any unread articles in newsgroups specified in file newsrc.save and mark them as read)

tin -R
    (read any articles saved by tin -S)

  RANGES
A range is simply a group of items marked using the SetRange ('#') key. Certain tin commands will operate on a range if one exists rather than just the current item. A range is an expression of the form <min>-<max>, e.g. 10-15 will highlight items 10 through 15 on the current screen. Other than absolute numeric positions, '.' can be used in place of the current cursor position and '$' can be used to mean the highest number available. Currently the only commands that understand ranges are GroupMarkThdRead ('K'), MarkArtUnread ('z') and MarkThdUnread ('Z').

  NEWSGROUP LISTS & WILDCARDS
Several places in tin allow you to specify a list of newsgroups. These include command-line groups, (un)subscribe groups, the AUTO[UN]SUBSCRIBE mechanism. The scope= attributes file tag and the filter file group= tag also use the same syntax. tin interprets this variable similarly to rn(1). It contains a list of patterns, separated by commas and possibly prefixed with exclamation points. An exclamation point negates the meaning of a match on this pattern, and can be used to cancel certain matches. Some examples:

alt.config news.*,!news.test

Matches alt.config and everything in the 'news' hierarchy except news.test

See the explanation for the $AUTOSUBSCRIBE variables for further examples.

tin will recognize a signature in either ${TIN_HOMEDIR-"$HOME"}/.signature or ${TIN_HOMEDIR-"$HOME"}/.Sig. If ${TIN_HOMEDIR-"$HOME"}/.signature exists, then the signature will be pulled into the editor for mail commands only. A signature in ${TIN_HOMEDIR-"$HOME"}/.signature will not be pulled into the editor for posting commands since inews(1) will append the signature itself.

A signature in ${TIN_HOMEDIR-"$HOME"}/.Sig will be pulled into the editor for both posting and mailing commands.

The following is an example of a .Sig file:
    NAMES  Joe Bar <joe@example.org>
    SNAIL  Musterweg 12, 99999 Notreal, Germany

tin also has the capability to generate random signatures on a per newsgroup basis if so desired. The way to accomplish this is to specify the default signature or the group attribute sigfile as a directory. If for example the sigfile path is /usr/iain/.sigs and .sigs is a directory then tin will select a random signature from any file that is in the directory .sigs (note: one signature per numbered file). A random signature can also consist of a fixed part signature that can contain your name, address etc. followed by the random sig. The fixed part of the random sig is read from the file $HOME/.sigfixed.

  TIPS AND TRICKS
tin can be pretty much be navigated by using the four cursor keys. The left arrow key goes up a level, the right arrow key goes down a level, the up arrow key goes up a line and the down arrow key goes down a line.

The following newsgroups provide useful information concerning news software:
—news.software.readers (info. about news user agents tin, rn, nn, slrn etc.)
—news.software.nntp (info. about NNTP)
—news.answers (Frequently Asked Questions (FAQ) about many different themes)

Many prompts within tin offer a default choice that the cursor is positioned on. By pressing '<CR>' the default value is taken. Most prompts can be aborted by pressing '<ESC>'.

When tin is run in an xterm(1x) it will resize itself each time the xterm(1x) is resized.

tin will reread the ${TIN_LIBDIR-NEWSLIBDIR}"/"${TIN_ACTIVEFILE-active} file at set intervals (reread_active_file_secs) to show any newly arrived news.

If you find large number of new newsgroups cluttering up your screen, pressing SelectToggleReadDisplay ('r') will make them go away.

  XTERM BUTTONS
If the environment variable $TERM is set to xterm(1x), then button pressing can be used to select groups and articles. In this discussion, the buttons are assumed to be assigned conventionally (i.e., Button1 is the left button).

In general (i.e., for the group, thread and article menus),

Button1 (left)
    enters next (lower) level if you click on an article, otherwise pages down.

Button2 (center)
    returns to the previous (upper) level if you click on an article, otherwise pages up.

Button3 (right)
    positions on the article line under mouse cursor, or pages down if you've clicked outside the list of articles.

In the group selection menu, if the mouse is pointing at a group then:

left button
    moves to and selects the group pointed at, just like SelectReadGrp ('<CR>').

center button
    quits the program, just like Quit ('q').

right button
    moves to the group pointed at.

In the article menu, if the mouse is pointing at an article (or thread) then:

left button
    reads the article pointed at, just like GroupReadBasenote ('<CR>'), or the thread, just like GroupListThd ('l').

center button
    exits the menu, catching up on the group if you have group_catchup_on_exit set in your configuration, just like Quit ('q').

right button
    moves to the article (or thread) pointed at.

In the thread menu, if the mouse is pointing at an article then:

left button
    reads article pointed at, just like ThreadReadArt ('<CR>').

center button
    exits the menu, catching up on the thread if you have thread_catchup_on_exit set in your configuration, just like Quit ('q').

right button
    moves to the article pointed at.

In other menus and areas button pressing reverts back to usual cut and paste of xterm(1x), but after one click of any button.

  INDEX FILES
If your news server supports NOV index files (see newsoverview(5), most modern installations will) and you have a fast connection to your news server then this section can be ignored.

If your news server doesn't support NOV index files or you have a very slow connection to your news server then tin can cache the index for each newsgroup if cache_overview_files is set to ON. Note that this cache can use up large amounts of diskspace if you read a lot of groups and/or high traffic groups.

Each user creates/updates his/her own index files that are stored in ${TIN_INDEX_NEWSDIR-"${TIN_HOMEDIR-"$HOME"}/.tin"}/.news/. If you are reading via NNTP then the news server name will be appended to keep the indexes for different servers separate. If you are reading off the local spool and local overview files already exist then turning on caching will have no effect. Likewise unless you see significant delays entering a group when reading via NNTP then turning on caching will have little or no effect.

Entering a group the first time tends to be slow because the index file must be built from scratch. To alleviate the slowness start tin to create all index files for the groups you subscribe to with tin -u -v and go for a coffee. Subsequent readings of a group will only need to do incremental updating of the index file and will be much faster as only new articles will need to be cached.

As indexing might take some time you may want to run tin form the system batcher cron(1) with the ''-u'' option:

    30 6 * * * /usr/local/bin/tin -u

If you are low on local disk space you should consider using getart_limit to limit the size of cached indexes and also manually purge cached data for groups you are not reading anymore with something like:

    find ${TIN_INDEX_NEWSDIR-"${TIN_HOMEDIR-"$HOME"}/.tin"}/.news* \
    -type f -name "[0-9]*.[0-9]" -atime +28 | xargs rm -f

ENVIRONMENT

TINRC
    Define this variable if you want to specify command-line options that tin should be started with to save typing them each time it is started. The contents of the environment variable are added to the front of the command-line options before it is parsed therefore allowing an option specified on the command-line to override the same option specified in the environment.

TIN_HOMEDIR
    Define this variable if you do not want the .tin directory in $HOME/. E.g., if you want all tin's private files in /tmp/.tin you would set $TIN_HOMEDIR to /tmp.

TIN_INDEX_NEWSDIR
    Define this variable if you do not want the .news directory in ${TIN_HOMEDIR-"$HOME"}/.tin/. E.g., if you want all tin's news index files in /tmp/.news you would set $TIN_INDEX_NEWSDIR to /tmp.

TIN_INDEX_MAILDIR
    Define this variable if you do not want the .mail directory in ${TIN_HOMEDIR-"$HOME"}/.tin/. E.g., if you want all tin's mail index files in /tmp/.mail you would set $TIN_INDEX_MAILDIR to /tmp.

TIN_INDEX_SAVEDIR
    Define this variable if you do not want the .save directory in ${TIN_HOMEDIR-"$HOME"}/.tin/. E.g., if you want all tin's save index files in /tmp/.save you would set $TIN_INDEX_SAVEDIR to /tmp.

TIN_LIBDIR
    Define this variable if you want to override the NEWSLIBDIR path that was compiled into the tin binary, default is /usr/lib/news. If tin is running in NNTP mode setting this variable has no effect.

TIN_SPOOLDIR
    Define this variable if you want to override the SPOOLDIR path that was compiled into the tin binary, default is /var/spool/news. If tin is running in NNTP mode setting this variable has no effect.

TIN_NOVROOTDIR
    Define this variable if you want to override the NOVROOTDIR path that was compiled into the tin binary, default is SPOOLDIR (see above). If tin is running in NNTP mode setting this variable has no effect.

TIN_ACTIVEFILE
    Define this variable if you want to override the NEWSLIBDIR/active path that was compiled into the tin binary. If tin is running in NNTP mode setting this variable has no effect. If $TIN_LIBDIR is set it is prepended to $TIN_ACTIVEFILE.

NNTPSERVER
    The default NNTP server to remotely read news from. This variable only needs to be set if the ''-r'' command-line option is specified and the file /etc/nntpserver does not exist. The ''-g'' command line option overrides $NNTPSERVER.

NNTPPORT
    The NNTP TCP-port to read news from. This variable only needs to be set if the TCP-port is not 119 (the default). The ''-p'' command-line option overrides $NNTPPORT.

DISTRIBUTION
    Set the article header field ''Distribution:'' to the contents of the variable instead of the system default.

ISO2ASC
    Set the ISO to ASCII charset decoding table character to use in decoding an article text. Values can range from 0 to 6.

ORGANIZATION
    Set the article header field ''Organization:'' to the contents of the variable instead of the system default. If reading news on an Apollo DomainOS machine the environment variable $NEWSORG has to be used instead of $ORGANIZATION.

NEWSORG (DomainOS)
    DomainOS specific, same as $ORGANIZATION on other OSs (see above).

REPLYTO
    Set the article header field ''Reply-To:'' to the return address specified by the variable. This is useful if you wish to receive replies at a different address.

NAME
    Overrides the full name given in the gecos-files in /etc/passwd, see also mail_address.

REALNAME
    Same as $NAME.

HOME
    Pathname of the user's home directory. See environ(5) for more infos.

MAILER
    This variable has precedence over the default mailer that is used in all mailing operations within tin. If reading news on VMS use $TIN_MAILER instead.

TIN_MAILER (VMS)
    VMS specific, same as $MAILER on other OSs (see above).

MAIL
    Full path to the users mailbox.

VISUAL
    This variable has precedence over the default editor (i.e., vi(1)) that is used in all editing operations within tin (e.g., posting, replying, follow-ups, ...). Evaluation order is ${VISUAL-"${EDITOR-vi}"}. See environ(5) for more infos.

EDITOR
    If $VISUAL is unset, then this variable is looked up for a default editor. If $EDITOR and $VISUAL are both unset, tin will uses the systems default editor (i.e. vi(1)) on UNIX-systems). See environ(5) for more infos.

AUTOSUBSCRIBE
    A new group is checked against the list of patterns; if it matches, tin subscribes the user to the group without further query. See the section "NEWSGROUP LISTS & WILDCARDS" for an explanation of the valid syntax. For example, setting

    AUTOSUBSCRIBE=comp.os.unix.*,talk.*,!talk.politics.*

    will automatically subscribe the user to all new groups in the comp.os.unix hierarchy, and all talk groups other than talk.politics groups (which will be queried for as usual). Of course this does not work if tin is started with the ''-X'' command-line switch.

AUTOUNSUBSCRIBE
    Is handled like the $AUTOSUBSCRIBE variable, but groups matching the list are unsubscribed from without further query. For example, setting

    AUTOUNSUBSCRIBE=alt.flame.*,u*,!uk.*

    will automatically unsubscribe the user from all new alt.flame groups and all groups starting with u (university groups) other than UK groups (which will be queried for as usual).

TMPDIR
    A pathname of a directory made available for tin to create temporary files.

MAILCAPS
    This variable can be used to override the default path search for mailcap files. See also tin(5).

NOMETAMAIL
    Set this variable to disable the use of metamail(1) or a replacement (e.g. metamutt).

MM_CHARSET

ISPELL
    Set this variable to point to ispell(1) or a replacement and its cmd-line options.

PGPOPTS
    Define any additional options that you wish to pass to your pgp(1) or gpg(1) program.

PGPPATH
    Override the name of the pgp(1) directory in $HOME that holds your keys etc..

GNUPGHOME
    Override the name of the gpg(1) directory in $HOME that holds your keys etc..

LC_CTYPE
    This variable determines the locale(5) category for character handling functions. Usually it determines the character classes for pattern matching character classification and case conversion. Currently this is not true for tin (which temporary unsets $LC_CTYPE right before any match is done to avoid confusion). It's value should be of the form language[_territory][.codeset][@modifier]. See environ(5) for more information.

LC_MESSAGES
    Formats of informative and diagnostic messages and interactive responses. It's value should be of the form language[_territory][.codeset][@modifier]. See locale(5) and environ(5) for more information.

LC_TIME
    Date and time formats. It's value should be of the form language[_territory][.codeset][@modifier]. See locale(5) and environ(5) for more information.

LC_ALL
    This variable overrides the value of the $LANG variable and any other $LC_ variable. It's value should be of the form language[_territory][.codeset]. See locale(5) and environ(5) for more information.

LANG
    This variable determines the locale(5) category for any category not specifically selected with a variable starting with $LC_. It's value should be of the form language[_territory][.codeset]. See environ(5) for more information.

COLUMNS
    A decimal integer > 0 used to indicate the user's preferred width in column positions for the terminal screen or window. If this variable is unset or null, the implementation determines the number of columns, appropriate for the terminal or window. When $COLUMNS is set, any terminal-width information implied by $TERM will be overridden. Users and portable applications should not set $COLUMNS unless they wish to override the system selection and produce output unrelated to the terminal characteristics.

LINES
    A decimal integer > 0 used to indicate the user's preferred number of lines on a page or the vertical screen or window size in lines. A line in this case is a vertical measure large enough to hold the tallest character in the character set being displayed. If this variable is unset or null, the implementation determines the number of lines, appropriate for the terminal or window. When $LINES is set, any terminal-height information implied by $TERM will be overridden. Users and portable applications should not set $LINES unless they wish to override the system selection.

TERM
    The type of terminal in use. This is used when looking up termcap sequences. See environ(5) for more information.

CONFORMING TO

HISTORY
tin is based on the tass(1) newsreader that was developed by Rich Skrenta and posted to alt.sources in March 1991; its first version was released on August 23rd 1991. tass(1) itself was heavily influenced by notesfiles a public domain UNIX version of PLATO Notes, developed at the University of Illinois by Ray Essick and Rob Kolstad in 1982. For a version overview see <http://www.tin.org/history.html>
