#### 2.8.5 Commands That Will Fail

Here are some sample commands you might try which will not work, and why they won’t work.

If you try to use this command,

    $ tar -xvf music.tar folk jazz

you will get the following response:

    tar: folk: Not found in archive
    tar: jazz: Not found in archive

This is because these files were not originally in the parent directory `..`, where the archive is located; they were in the `practice` directory, and their file names reflect this:

    $ tar -tvf music.tar
    practice/blues
    practice/folk
    practice/jazz

Likewise, if you try to use this command,

    $ tar -tvf music.tar folk jazz

you would get a similar response. Members with those names are not in the archive. You must use the correct member names, or wildcards, in order to extract the files from the archive.

If you have forgotten the correct names of the files in the archive, use `tar --list --verbose` to list them correctly.

To extract the member named `practice/folk`, you must specify

    $ tar --extract --file=music.tar practice/folk

Notice also, that as explained above, the `practice` directory will be created, if it didn’t already exist. There are options that allow you to strip away a certain number of leading directory components (see transform). For example,

    $ tar --extract --file=music.tar --strip-components=1 folk

will extract the file `folk` into the current working directory.
