How to find all commits(files&comments) by a person in cvs

cvs history -a -c  -D 2009-01-20

to review all commits by all users since 2009-01-20

Here's a quick oneliner that will give you a list of every file, followed by changes in that user and the first line of comment from that user.

cvs log | egrep -A 1 'Working file|username'

Output will look like:

Working file: bin/scriptname
head: 1.14
--
date: 2008/01/01 15:15:30;  author: username; state: Exp; lines +3 -2
First line of checkin comment will appear here.

This is a quick and dirty one liner, so YMMV.
