How to test a cron job?

You can update the MAILTO variable to your email address, and cron should email you any STDOUT and STDERR output. Also check your syslog file /var/log/messages to see if the script is being executed by cron Tony.

If so, it contains nothing about my cron, which would indicate it isn't running. I haven't got email set up on my machine yet, so I'll give that a go and see what shakes out. – Dave May 2 at 14:38 There is nothing written to /var/log/messages but adding a MAILTO variable above the crontab line gives the feedback I was looking for.

Cron should mail it results so it looks like you have a problem. Here, it seems you are missing a user to run the script as : 00,06,12,18 * * * user_name /opt/scripts/selenium/run_nis_inf_tests. Sh replace user_name by the name of the user the script needs to be run by, verify permissions of "run_nis_inf_tests.

Sh" and you should be ok.

When I tried your suggestion (adding the username), I got the error, "/bin/sh: selenium: not found". The syntax I use is, "00 */1 * * * /opt/scripts/selenium/run_nis_inf_tests. Sh".

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
