why my cron job executing multiple times?

Question

5 8 * * * /sh_f         


        

Answer 1

Without more knowledge about your particular setup/system, and the fact that all jobs get executed multiple times, I can only surmise that you have multiple cron daemons running on your system.

Do a full process list and grep for cron (most of them have that word in the name of the binary) and see how many are running. On a standard linux system, this should work:

ps aux | grep cron

Then you would have to figure out which should be running and kill the others.
