Run that as a script, making changes for your system where appropriate and then run that script from cron. Cron makes very few assumptions about your environment, your PATHS and other environmental variables are not getting set. If you run this a script suing "#!/bin/sh" you should get a default environment as defined by your installation. -geoff --------------------------------- Geoff Galitz Blankenheim NRW, Germany http://www.galitz.org/ http://german-way.com/blog/
