Currently I have a
crontab entry that does the following:
#!/bin/bash /etc/init.d/sendmail stop /etc/init.d/sendmail start /usr/bin/newaliases
In the category of "learn something new every day", I just came across
watch (http://ss64.com/bash/watch.html), and am wondering how to implement the updating of the
sendmail aliases database via watching
/etc/aliases for changes, rather than just blindly bouncing
smtpd every day whether or not an update has occurred.
What is the right way of going about this, and should it still be run as a
crontab entry, or can it be more-or-less daemonized?
