Crontab run every 15 minutes except at 3AM?
LinuxUnixCronLinux Problem Overview
Is it possible to have a cronjob run every 15 minutes (over every hour etc..) except for at 3AM?
I have another special cronjob I want to run at 3AM, but I don't want the other one to run at the same time...

Solution 1 - Linux
With one cron line, no. With three, yes:
# Every 15 minutes except for 3:00-3:59
*/15 0-2,4-23 * * * thejob
# 3:15, 3:30, 3:45
15-45/15 3 * * * thejob
# 3:00 dead
0 3 * * * otherjob
Solution 2 - Linux
I made my own solution, but I wanted to see what other people thought of!
I put this on the top of my desired script. I wanted it to not run at the half hour either so it doesn't do it on both.
On top of the script:
if [ $(date +%M) = 00 ] || [ $(date +%M) = 30 ]
then
exit
fi
The cron line:
*/15 * * * * ~/path/to/file
Hope anyone uses my solution too.
