Thanks for the quick reply. Unfortunately it made no difference putting #!/bin/bash... This works on every other system I've tried. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx]On Behalf Of Miskell, Craig Sent: 29 January 2007 00:07 To: General Red Hat Linux discussion list Subject: RE: Simple bash problem. > Anyone know why the following simple bash script fails > on RHEL3 (fully patched)?

Try #!/bin/bash and see how that goes, Craig ======================================================================= Attention: The information contained in this message and/or attachments from AgResearch Limited is intended only for the persons or entities to which it is addressed and may contain confidential and/or privileged material.
