Topic:
Unix Operating Systems;;
I would like cron to log start and end times for each job run. I know how to do this in DEBIAN but not red hat.

I will try that...but thought it was only for debian based distros...
Tried the crondargs, but it throws an error in RHEL. I think that param is for Debian based distros. Thanks though!

You could try setting higher log level for cron in /etc/sysconfig/crond :
CRONDARGS= -L 2
and then restarting cron : sudo service cron restart
My preference is the solution you've chosen so you can easily keep track of all jobs in one place. And the cron log itself is not accessible for users.

This will work, but I'm looking for system level logging for all cron jobs if possible.

Thanks Gerwin. I have hundreds of cron jobs. I think this is a great solution, but was hoping there was a system level logging setting that I could enable.

500 points GOOD
Simplest is to write wrapper commands (or script)
The wrapper logs start date/time with the cron script's name, calls the cron script and logs end date/time.
Easiest if you give every cron script it's own log file name.
For example:
The wrapper logs start date/time with the cron script's name, calls the cron script and logs end date/time.
Easiest if you give every cron script it's own log file name.
For example:
00 10 * * * echo "`date` Start of cron1" >> /home/user/cronjob1.log ; /home/user/cronjob1 ; echo "`date` End of cron1" >> /home/user/cronjob1.log 1:

Thanks Duncan, but I know how to use cron. I need to know how to get a start and end time for each of the jobs. Currently, cron logs start time and thats it.
Thanks,
Shawn

For example,
*/10 * * 5,7,11 * root command1
0 9-18 * * 1-5 root command2
These lines will run command1 every ten minutes during May, July and November, and command2 once an hour during the working day (09:00 to 18:00) Monday to Friday.
