: I think the append flag is 'A', but you can't append to a compressed
: archive, so I guess I have to do..


: tar cf mytar.tar foo/ bar/
: cd long/path/to
: tar Af ~/mytar.tar logfile.log
: bzip2 ~/mytar.tar

If they're on the same filesystem, personally I'd probably end up doing
something reasonably icky as:

ln long/path/to/logfile.log .
tar cvf - foo bar logfile.log | bzip2 > my.tar.bz2
rm logfile.log

if I couldn't find a nicer way of doing it.

You possibly are.  OTOH, you can do wonders with LD_PRELOAD, you know :-)

Due to constant nagging to change it, my .sig is temporarily unavailable.
Normal service will be resumed as soon as possible.  We apologise for the
inconvenience in the meantime.
