This question already has an answer here:
setup cron tab to specific time of during weekdays
I have certain jobs to be run in a specific time .
for example :
at 00:20:00 ls
at 04:20:00 ls -l
at 08:20:00 ls -ltr
at 12:20:00 ls -ltrh
How can run this at these specific time based on some conditions . Like if it is 00:20:00 , it should only run ls , it should not run the other three .
Can anyone help ?
