This is not CentOS-specific, hence OT.
I need a list of all email users on my system (there are hundreds of them).
The list could be extracted from /etc/aliases and the virtusertable.
Does anyone know of a script that would do this automatically? It would have
- exclude commented-out lines (of course)
- exclude duplicates
- produce a list of usernames (or maybe unresolved email addresses for some
users) separated by a comma
I imagine perl would be the way to go. I haven't used perl at all myself.
