System name: hodge-podge
Type and version: KN01 7.7F (1 update(s) to same version)
Display type: PMAX-MFB
What were you trying to do?
Use the V (extended verbose information) option to tar.
What's wrong:
It doesn't work any more:
% /afs/athena/system/pmax_ul4/srvd.76/bin/tar tV
{does something}
% /afs/athena/system/pmax_ul4/srvd.77/bin/tar tV
tar: V: unknown option
tar: usage: tar -{txru}[cvfblmhopwBi] [tapefile] [blocksize] file1 file2...
I think the version of tar previously available on vax and rt
systems was built for Ultrix and installed in place of Ultrix tar,
although I didn't see any mention of that in the release notes. The
installed man page (/usr/man/man1/tar.1) is still the Ultrix version,
however. It documents the A, D, C, F, FF, H, M, N, O, P, R, S, V, d,
an s options, which don't appear in the usage message for /bin/tar.
What should have happened:
The version of tar distributed with Ultrix should have been
left in the release as /bin/tar. The new version causes previously
written backup scripts for Ultrix to fail, and may cause users to
be unable to restore files, if they happened to choose an option to
write a tape in a format that only Ultrix tar can handle.
Please describe any relevant documentation references:
