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:
Why would the behavior be any different? Could it be that cron is
running it an entirely different shell, that doesn't understand the "if"
statement?
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.
