Webcam snapshot on every git commit

gistfile1.sh

#!/bin/bash
#
# This script will make a webcam snapshot every commit. The jpg file will have 
# the commit id as the filename.
#
# This script requires imagesnap. Install with: 'brew install imagesnap'
#
# Put this file in the '.git/hooks/' name it 'post-commit' and chmod it by:
# 'chmod +x .git/hooks/post-commit'
#
# Make sure the .gitshots directory exists in the root of the repo.
#
# Inspired by Victor Martinez (http://coderwall.com/p/xlatfq?p=1&q=)
#
#
# Todo:
# * Check if '.gitshots' excists otherwise make it!
# * Add snapshot on pre-commit to repo
#

COMMITID=$(git rev-parse HEAD)
imagesnap -q -w 1 .gitshots/$COMMITID.jpg

@jellea, do you know if your script lags after each commit while producing webcam snapshot? Or you still need to wait for camera to take a picture?

@manakor Adding an ampersand at the end of the last line should prevent the script from lagging.
