What about reading directly from the groupinfo database?  I'd rather
backup the database before doing anything fancy, though.  Here's a
simple example:


#!/usr/bin/env python

# 0755 noffle_active_re.py
# Tested at least once.  Works for me but your mileage may vary.
# Requires Python incl. gdbm module

import gdbm, re, string, struct
import sys

groupdb = "/var/spool/noffle/data/groupinfo.gdbm"

def active_re( pattern ):
    searcher = re.compile( pattern, re.IGNORECASE ).search
    db = gdbm.open( groupdb, "r" )
    matchlist = filter( searcher, db.keys() )
    matchlist.sort()
    for a in matchlist:
        entry = db[a]
        (first, last, remotelast, createdTime, 
         lastAccessTime) = struct.unpack( "iiiii", entry[:20] )
        (server, description) = string.split( entry[20:-6], "\0" )
        (postAllow, lastPostTime) = struct.unpack( "=ci", entry[-5:] )
        # print groupname without "\0"
        print a[:-1], last, first, postAllow
    return

if len( sys.argv ) > 1:
   active_re( sys.argv[1] )
else:
   print "Usage: %s pattern" % sys.argv[0]
