Hi Folks,
I have a script running every minute via cron, I want
to stop it running more than once simultaneously.
(ie sometimes it takes longer than 1 minute to run,
and I don't want it running twice at the same time)
I think adding the following line will prevent this
Can I have your comments please ?
Note, the name of the script is watcher.sh
if (ps -ef |grep -v $$| grep -v grep | grep
"watcher.sh" > /dev/null)
then
exit
fi
Is there a better way...
I want to avoid using flag files, since these can
cause problems in the event of a crash
