cron will email you the output of any program it runs (if there is any output). So, if you don't get any output, there are basically three possibilities:
crond could not even start a shell for running the program or sending email
crond had troubles mailing the output, or the mail was lost.
the program did not produce any output (including error messages)
Case 1. is very unlikely, but something should have been written in the cron logs. Cron has an own reserved syslog facility, so you should have a look into /etc/syslog.conf (or the equivalent file in your distro) to see where messages of facility cron are sent. Popular destinations include
and
In case 2., you should inspect the mailer daemon logs: messages from the Cron daemon usually appear as from
. You can use a
line in the crontab file to have cron send email to a specific address, which should make it easier to grep the mailer daemon logs. For instance:
In case 3., you can test if the program was actually run by appending another command whose effect you can easily check: for instance,
so you can check if crond has actually run something by looking at the mtime of /<some -path>/sucessfullrun
I would suggest that the shell is expanding the *.nmon in the current directory before trying to execute the command.
Try this to pass the wild-card value straight through to the find command:-
I have corrected the \\ into \; and captured the errors too.
Of course, you are assuming that it is being called at all. Consider stoping your cron process. It should re-start and re-read your crontab file. You are editing the file with crontab -e aren't you? Changing the clock can also upset the cron process.
cron process in AIX is there when I do ps -ef |grep cron, but none of cron job is working. It appears that cron process is hanging or having some issues? How do you resolve this? Do I kill the cron process by kill -9 PID? and how to start it?
Please advise. (1 Reply)
