Over several years, I have built-up a suite of backup scripts. The
scripts report errors and other status to the console using 'echo',
'ls' and 'cat'. I would like to run these as a cron job. Will output
to stdout cause
problems or just be ignored?

by default output of stdout and stderr are emailed to the running user
of the cron... you can disable this by adding MAILTO="" to the
beginning of your cron, in which case stdout and stderr will go
nowhere... or you could go through your scripts and redirect stdout
and stderr to /dev/null

Very instructive - thanks!

Wouldn't you want these to be placed into a log file instead of going
where nobody will see them? For example

/path/to/your_script >/path/to/your_logfile 2>&1

Good idea, Scott! stderr has always been re-directed to an error log;
so I could just redirect my own error reporting there.
