[rrd-users] Re: Simple shell script nor working properly

[Darryl Lewis]

When a program is run from cron, it doesn't have any of your environment settings. Basically, it doesn't know where the program is, or what directory it should be working in.
If you add

#! /bin/sh

cd /home/{user}/{directory}

it should work.
note that you should replace {user} and {directory} with the correct path. You can get this by typing pwd and put that in the cd line.
