Title: Crontab not running. What am I doing wrong?!
Post by: Joe Bob on November 13, 2003, 01:42:34 AM

Ack!    I have banged my head on the wall for hours now.

To test to make sure it will work, I created a cron job by doing this:

crontab -e

i
10 * * * * wget http://weather.unisys.com/satellite/sat_ir_west.gif -O /home/e-smith/files/primary/html/contest/test.gif

:wq

As I understand it, that should get the image every 10 min and stick in in the directory listed.  

If I enter this on the command line, it does work:
wget http://weather.unisys.com/satellite/sat_ir_west.gif -O /home/e-smith/files/primary/html/contest/test.gif

I have some other useful cronjobs to set up, but for the life of me cannot seem to get even a simple one to run.

Any help is VERY appreciated.

Thanks.

Probably crontab can't find wget. Try /usr/bin/wget.

Tried that.  Still no go.

Other suggestions?  

I am dying here trying to figure this out.

Crontab from HELL!

Follow up:

Problem solved.

I realized that
5 * * * *  command
means that it will run at 5 after the hour, not every 5 min!  Doh!

Got it working now.

One more question:
Any way to turn off the emails the Cron Daemon sends me every time a cron job runs?  

Thanks again for all the help fellow SME Server users!

Well I missed that one, and I should have known better!

Redirect the output to /dev/null like so:

5 * * * *  command  > /dev/null (if you still want to see error messages)

or

5 * * * *  command > /dev/null 2>&1 (if you don't want to see any messages at all)
