I love the flag idea. Its easy to implement and doesn't involve messing with my production crontab file.
Thanks.

something like
crontab -l >/tmp/oldcron
cat /tmp/oldcron | do modifications >/tmp/newcron
crontab newcron
should work
for you problem it would be easier if you backup-scripts set some flag; f.e. touch /tmp/backuprunning
then your crontab-scripts could check this flag and exit if it exists -> no crontab modification necessary

This seems like it should be simple, but my brain isn't able to wrap itself around the problem this morning. Perhaps its all the snow.
My weekly backup stops our production databases and I'd like to comment out some cron jobs so they don't generate a bunch of errors while the backup is running, then uncomment them when the backup completes. Anyone have a good ksh syntax for how to edit a crontab file from a ksh script?
