Editfiles, DeleteCommands, POSIX Syntax, etc

[Brian E. Seppanen]

Hello:

I'm desperate to use editfiles for some ACL maintanence, and to do so I
need to insure that I can clear a couple of lines with the DeleteCommands,
unfortunately I cannot, for the life of me, define a regex or pattern that
will match, and I'm frankly baffled.  I need to match

        only_from       += 192.168.0.0/24

In all cases I've been careful to escape the + and the .'s   I've had luck 
with a BeginGroupIfNoMatch, so I'm pretty sure, I haven't missed escaping 
something.

I can specifically key on the +=, I've tried everything that I can think 
of using DeleteLinesMatching, DeleteLinesStarting, and 
DeleteLinesContaining, and nothing has worked.  I'm using cfengine-2.0.5 
on solaris and linux.

Is there any site that might have some examples of POSIX regular 
expressions that I could look at.   Seeing some examples may be all that I 
need.   Would someone be willing to suggest some examples using the above 
format???

Thanks,   I really appreciate it.
