#### 4.2.5 Removing Archive Members Using `--delete`

You can remove members from an archive by using the `--delete` option. Specify the name of the archive with `--file` (`-f`) and then specify the names of the members to be deleted; if you list no member names, nothing will be deleted. The `--verbose` option will cause `tar` to print the names of the members as they are deleted. As with `--extract`, you must give the exact member names when using ‘`tar --delete`’. `--delete` will remove all versions of the named file from the archive. The `--delete` operation can run very slowly.

Unlike other operations, `--delete` has no short form.

This operation will rewrite the archive. You can only use `--delete` on an archive if the archive device allows you to write to any point on the media, such as a disk; because of this, it does not work on magnetic tapes. Do not try to delete an archive member from a magnetic tape; the action will not succeed, and you will be likely to scramble the archive and damage your tape. There is no safe way (except by completely re-writing the archive) to delete files from most kinds of magnetic tape. See Media.

To delete all versions of the file `blues` from the archive `collection.tar` in the `practice` directory, make sure you are in that directory, and then,

    $ tar --list --file=collection.tar
    blues
    folk
    jazz
    rock
    $ tar --delete --file=collection.tar blues
    $ tar --list --file=collection.tar
    folk
    jazz
    rock

The `--delete` option has been reported to work properly when `tar` acts as a filter from `stdin` to `stdout`.
