How to get a list of Dovecot IMAP users

Question

What does "element" selector in Primefaces CSS mean/do? And how to access it, change css rules inside it?.

please check this image for details

Background: I am trying to change width of PrimeFaces element, selectOneMenu for example, but what seems to be blocking me is style rule inside element{}- min-width in my case. I would like to override it in custom css or with style attribute but don't know how to access it.

I've unsuccessfully tried:

• p:selectOneMenu style="min-width:100px"
• applying styleClass

Solution

To get a list of logins:

cat /var/log/mail.log | grep imap-login 

Now we need to cut it down to something a little more useable -- filter out the username, and eliminate duplicates:

cat /var/log/mail.log | grep imap-login:\ Login | sed -e 's/.*Login: user=<\(.*\)>, method=.*/\1/g' | sort | uniq

This gets the imap logins that complete (supply a name), uses sed with a regex to cut out the name, sorts it and then takes the unique names.

Thank you! So much cleaner than the PHP script I wrote to do it. I REALLY need to learn how to use regex without just googling ten million different things until something works.
