FIXME: Should the arg to --label be a quoted string?? no - ringoTo avoid problems caused by misplaced paper labels on the archive media, you can include a label entry--an archive member which contains the name of the archive--in the archive itself. Use the `--label=archive-label' (`-V archive-label') option in conjunction with the `--create' (`-c') operation to include a label entry in the archive as it is being created.
If you create an archive using both `--label=archive-label' (`-V archive-label') and `--multi-volume' (`-M'), each volume of the archive will have an archive label of the form `archive-label Volume n', where n is 1 for the first volume, 2 for the next, and so on.
FIXME: xref Multi-Volume Archives, for information on creating multiple volume archives.
If you extract an archive using `--label=archive-label' (`-V archive-label'), tar will print
an error if the archive label doesn't match the archive-label
specified, and will then not extract the archive. You can include
a regular expression in archive-label, in this case only.
FIXME: why is a reg. exp. useful here? (to limit extraction to a FIXME: specific group? ie for multi-volume???
To find out an archive's label entry (or to find out if an archive has
a label at all), use `tar --list --verbose'. tar will print the
label first, and then print archive member information, as in the
example below:
% tar --verbose --list --file=iamanarchive V--------- 0/0 0 Mar 7 12:01 1992 iamalabel--Volume Header-- -rw-rw-rw- ringo/user 40 May 21 13:30 1990 iamafilename
FIXME: was --volume
