I'm trying to parse various info from log files, some of which is placed within square brackets. For example:

Tue, 06 Nov 2007 10:04:11 INFO     processor:receive: [someuserid], [somemessage]  msgtype=[T]

What's an elegant way to grab 'someuserid' from these lines, using sed, awk, or other unix utility?
