RE: Simple bash problem.



Thanks for the quick reply.

Unfortunately it made no difference putting #!/bin/bash...

This works on every other system I've tried.

I'm not 100% sure, but I think it might be because of the #! Line.  Bash
might be seeing that you've invoked with "/bin/sh", and is deciding to
operate in limited POSIX shell mode (sorry, the exact terminology for
that escapes me).  Try #!/bin/bash and see how that goes,
