Yes, that is the format of the list.

I actually solved the problem another way, I always thought the heading line was superfluous in this case anyway.

This is for a procs test for the z/VM client that I'm writing.  In this case a dispatchable unit of work is a virtual machine, so the 'process' list contain the names of the virtual machines.  Well since it is just a list of names and not process numbers, CPU Time, command, etc, I just changed the back-end client code to not require the heading line coming from the client.

Thanks to all who responded.

I've checked the PCRE tutorial and several other sites and I can not find a good match to what I'm trying to do.  I've also run several iterations through pcretest with no joy.

I have a list of users (actually virtual machine names) with the heading 'UserID'.  I would like to set up a regex to match any of them, except for the heading.  Basically, to count the machines, but ignore the heading line.

I've tried variations of "(!Userid|.*)" with no luck.
I guess you want to do it something like the procs column.

If the format is :

Userid
john
jane

you might want to try that :

^(?!Userid)(.+)

(Search the string "look-ahead assertion" in perlre(1) for some
explanation of this. Don't forget to add the preceding % in your
configfile.

It basically permits one to make pattern match only if they are not
preceded or followed by certain expressions. (Very useful when
piggy-parsing HTML :).
