Alan, > Sorting shell scripts, even if they are just settings, seems > like a bad policy decision in general. Edwin has made the point: /etc/rc.conf is NOT a shell script, it is a collection of settings. I agree that it messes with comments, so what I do is something like this: ---------------------------------- sendmail_enable="YES" # Enable the sendmail daemon named_enable="NO" # DNS is running on 'apollo' inetd_enable="YES" # I need this to kick ftpd ---------------------------------- This way the sort simply results in: ---------------------------------- inetd_enable="YES" # I need this to kick ftpd named_enable="NO" # DNS is running on 'apollo' sendmail_enable="YES" # Enable the sendmail daemon ---------------------------------- One ADVANTAGE of sorting it is that you will quickly see when you have a duplicated entry (this little problem has caused me numerous grey hairs in the past!). If you have: ---------------------------------- sendmail_enable="YES" # Enable the sendmail daemon named_enable="NO" # DNS is running on 'apollo' inetd_enable="YES" # I need this to kick ftpd # Other lines here sendmail_enable="NO" # Disable during (whatever) ---------------------------------- you might pull your hair out (actually, that's what I did! I'm going bald, not grey!) trying to figure out why sendmail won't start during boot, because whenever you look at rc.conf you (human) see the first line which says its enabled, but fail to notice the later line which some careless sysadmin left lying around! After sorting you have: ---------------------------------- # Other lines here inetd_enable="YES" # I need this to kick ftpd named_enable="NO" # DNS is running on 'apollo' sendmail_enable="NO" # Disable during (whatever) sendmail_enable="YES" # Enable the sendmail daemon ---------------------------------- and now it is obvious even at a casual glance that you have an anomoly to sort out.
