Just try to find your BACKUP :))
Very funny :))) Didn't have a backup... :))) ohh dear laughing at lost
work...:)))
Seems like I need pickup new skills on making "proper/better" backups
Thanks for making me laugh...much appreciated :)))
Actually better skills at scripting might be job one, use of "rm -rf" is ALWAYS
dangerous, I suggest putting temporary stuff in a subdir using the process id,
and deleting that at the end. If you miss you don't delete anything.
MyWk=joe-$$-$RANDOM
mkdir ${MyWk} || exit 2
# do stuff
rm -rf ${MyWk}
I would qualify that as "less unsafe" rather than idiot proof, but using both
the process id and a random number does avoid reusing a name. Note that if the
mkdir fails the script bails out immediately. Belt and suspenders programming.
