UNIX for Dummies Questions & Answers

every last sunday of each month, i recycle my application servers btw 1am - 2am.

before i recycle my apps servers, i have to login to each user to:

crontab -l > user1.crontab
crontab -l > user2.crontab
crontab -l > user3.crontab

when all my apps started, i have to cat user1.crontab and crontab -e to edit each user.

is it a way to disable user1, user2 and user3 crontab btwn 1-2am ?

Use a root cron job to put the usernames into cron.deny at 1am and remove them again at 2am?

I am curious: but what has crontab to do with a reboot? At least on AIX a shutdown doesn't change anything in crontab ... what do you do after the reboots - starting all the user cronjobs ?

Kind regards

not reboot; just shutting down all third party apps for cold backup. during 1-2am, i don't want user1,2,3 to kick off its cron jobs.

Why not modify the relevant cronjobs so that they look for the existance of a file such as /etc/nocronjobs? While that file exists, the cronjobs do not run.
