Re: Weird shell script behavior in a cron job

["James H. H. Lampert" <jamesl@touchtonecorp.com>]

A few minutes ago, with respect to my backup script attempting to mount 
ExternalHD if run from a command line, but not from cron, I wrote:

That was it. I added a line to echo $SHELL to my debugging log file, and 
that was it: if I ran it from cron, $SHELL was /bin/sh; if I ran it from 
a command line, $SHELL was /bin/bash.

Changing the shebang from
> #!
to
> #! /bin/bash

did the trick, and when I looked back at the original script, I found a 
shebang of
> #! /bin/sh

which I also changed. High hopes for finding successful test results 
tomorrow morning.
