## 3 Invoking GNU `tar`

This chapter is about how one invokes the GNU `tar` command, from the command synopsis (see Synopsis). There are numerous options, and many styles for writing them. One mandatory option specifies the operation `tar` should perform (see Operation Summary), other options are meant to detail how this operation should be performed (see Option Summary). Non-option arguments are not always interpreted the same way, depending on what the operation is.

You will find in this chapter everything about option styles and rules for writing them (see Styles). On the other hand, operations and options are fully described elsewhere, in other chapters. Here, you will find only synthetic descriptions for operations and options, together with pointers to other parts of the `tar` manual.

Some options are so special they are fully described right in this chapter. They have the effect of inhibiting the normal operation of `tar` or else, they globally alter the amount of feedback the user receives about what is going on. These are the `--help` and `--version` (see help), `--verbose` (see verbose) and `--interactive` options (see interactive).
