#!/bin/bash

# This script will submit all pending commits to gerrit and will automatically
# add reviewers to the associated change. Reviewers can be added by simply
# listing them after greview. You can either enter their full email addresses
# or just partially enter a unique combination of letters that will be
# fuzy-matched to either the email or the name of the commiters.

# Usage: greview <reviewer-1> <reviewer-2> ...

Thanks for the tips! The sed expression needed a bit of change to work properly, but it's working great now. I'm also limiting the number of commits to 1000 so that there's no performance hit in large repos. =D
