Hello Avon!
On 06 Aug 2021, Avon said the following...

Then you could try something like this in your BBS user's crontab (crontab -e as the BBS user):
SHELL=/bin/bash
* * * * * if [ ! -z "$(find /mystic/echomail/in/ -xdev -type f -iname '*.gal'
-print -quit)" ]; then /path/to/gal_maint.sh; fi
* * * * * if [ ! -z "$(find /mystic/echomail/in/ -xdev -type f -iname '*.fhr'
-print -quit)" ]; then /path/to/fhr_maint.sh; fi
This would run the checks every minute.
Or place it in the system-wide crontab directory, e.g. in a file /etc/cron.d/custom_bbs, but then you'll have to specify the username of the BBS user om each crontab line, too:
SHELL=/bin/bash
* * * * * bbs if [ ! -z "$(find /mystic/echomail/in/ -xdev -type f -iname '*.gal' -print -quit)" ]; then /path/to/gal_maint.sh; fi
* * * * * bbs if [ ! -z "$(find /mystic/echomail/in/ -xdev -type f -iname '*.fhr' -print -quit)" ]; then /path/to/fhr_maint.sh; fi
(Username "bbs" in the example.)
If the scripts output anything (information or error messages), that will be sent to the "bbs" user's local mailbox, or forwarded (e.g. to an e-mail address) if there is one specified in /etc/aliases:
bbs:
[email protected]
If you edit /etc/aliases, make sure to run 'newaliases' afterwards to be on the safe side (that it catches the change).
Oh, and the reason for SHELL= in the crontabs are that cron usually defaults to /bin/sh for the shell to run the *cron line* with, and on some systems /bin/sh nowadays point to /bin/dash, a different and simpler shell, so if you have some complex expressions on the cron line, it might barf...
Your *scripts*, though, will execute their code with the shell specified on their first line (#!/bin/something, usually #!/bin/bash).
Hope this helps!
Best regards
