wget does not work when called by cron

kapster · 09-26-2007, 09:26 PM

I have shell script that downloads a webpage using wget..
The abouve step works fine once I do a export http_proxy.

Now when I try to run the script using KCron....the wget does not work...I think I am missing some proxy settings with respect to cron.

Any pointers to solve this problem is appreciated

Thanks

The environment in which cron runs scripts is not the same as the normal user, environment variables might not be present, and the PATH variable is going to be shorter.

When putting a script into cron, it is best to hardcode your variables, to be sure that it won't be missing some critical bit of information when it comes time to run. Also be sure to give the complete path to commands, so you would use "/usr/bin/wget" rather than just "wget".

The point from MS3FGX is right. Regarding the proxy settings, you can simply put the http_proxy entry in your local configuration file $HOME/.wgetrc (if missing you can copy /etc/wgetrc to $HOME/.wgetrc and modify accordingly). wget should look for this file even from crontab execution.
