Display a git repository's commit graph with live updates

live-commit-graph.sh

#!/usr/bin/env sh

#  Display a git repository's commit graph with live updates.
#
#  I learned about Ben Hoskings' https://github.com/benhoskings/omglog
#  (`gem install omglog`) project while watching PeepCode's "Advanced Git"
#  course (now at
#  http://pluralsight.com/training/Courses/TableOfContents/advanced-git).
#  `omglog` shows the commit graph with live updating as commits are made,
#  merged, and branched. It is particularly helpful when run on a secondary
#  terminal window to inspect how the commit graph changes.
#
#  This shell one-liner tries to achieve a similar result:

while true; do clear; git --no-pager log --decorate --oneline --graph --all -n 20; sleep 3; done
