extraneous %s in error message

[Denis Excoffier-3]

Hi list,

I report here a minor bug in the last tar.

jupiter% tar --version | head -1
tar (GNU tar) 1.22.90
jupiter% tar tvf /dev/null --owner=no-such-owner /etc/passwd
tar: no-such-owner: Invalid owner
tar: Error is not recoverable: exiting now
jupiter% tar tvf /dev/null --group=no-such-group /etc/passwd
tar: no-such-group: %s: Invalid group
tar: Error is not recoverable: exiting now
jupiter%

The second error message is probably wrong (extraneous `%s: ').

By the way, it seems to me that it should be possible to have
these commands (above) succeed. After all, the tar file is not
dedicated to local consumption: the local existence or
nonexistence of any group or owner is not sufficient to forbid
the creation of such a tar file.

Regards.

Denis Excoffier.

It should have been

jupiter% tar cvf /dev/null etc.

instead. Also for the second line. Sorry for that.

Tar format needs to store both the numeric UID/GID
and the user/group name.  If the name cannot be
looked up in the local system database, it has
no way to generate a suitable ID.

Thanks for reporting. I fixed it in the repository.
