Welcome stahl,

Part of the problem is that when you execute the script from the command line, you have all the environmental variables set up for you. Unfortunately when you run the script(s) from 'crontab', you more than likely have a totally different set of environmental variables.

Try running a script from crontab that captures the environmental variables ( 'env' command ) to a file and then run the same script to a different file. Use 'diff' to find the differences and then your script will have to initialize those variables for crontab. You also want to give the full path for all commands since the PATH s may be different. You'll know for sure when you see the diff results.

Good Luck
