Crontab run every 15 minutes except at 3AM?
提问by Eric Seifert
Is it possible to have a cronjob run every 15 minutes (over every hour etc..) except for at 3AM?
除了凌晨 3 点之外，是否可以每 15 分钟（每小时等）运行一次 cronjob？
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...
我有另一个特殊的 cronjob 我想在凌晨 3 点运行，但我不希望另一个同时运行...

With one cron line, no. With three, yes:
有一个 cron 行，没有。三个，是的：
# 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

I made my own solution, but I wanted to see what other people thought of!
我做了自己的解决方案，但我想看看其他人的想法！
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.
我把它放在我想要的脚本的顶部。我希望它也不要在半小时内运行，所以它不会同时运行。
On top of the script:
在脚本之上：
if [ $(date +%M) = 00 ] || [ $(date +%M) = 30 ]
then
exit
fi
The cron line:
克隆线：
*/15 * * * * ~/path/to/file
Hope anyone uses my solution too.
希望有人也使用我的解决方案。
