Whenever I run this script -- or several others like it

# Script to back up all browser files in directory /home/ken/mozilla.
STARTDIR=$PWD
cd /home/ken
tar -czf /media/fde/backups/kbrowsers.tgz --exclude-caches \
- --wildcards -T docs/tarlists/kbrowsers.lst
cd "$STARTDIR"
it returns the following:
ken@Turing:~$ tarkbrowsers
tar (child): /media/ssda/backups/kbrowsers.tgz: Cannot open: No such
file or directory
tar (child): Error is not recoverable: exiting now
tar: /media/ssda/backups/kbrowsers.tgz: Cannot write: Broken pipe
tar: Child returned status 2
tar: Error is not recoverable: exiting now
It is trying to save the tarball to a different portable storage
device, ssda, which had failed and consequently is no longer in
/etc/fstab. How could such a thing happen?
There is nothing inherently wrong with the script, in that it would work
if all other things were equal, but they are clearly not.
Do an 'ls -l' on '/media/fde/backups', does it reveal anything? It might
well do.
Using the -C option to tar is preferable to the way you are doing it. So,
tar -czf /media/fde/backups/kbrowsers.tgz --exclude-caches --wildcards -C
/home/ken
-T ./docs/tarlists/kbrowsers.lst
might be better. You will return to your starting location then,
without the need for STARTDIR gubbings.
Mike.
