I\'m accustomed to running a git comparison that will allow comparison with local git revs like:
git diff HEAD HEAD~110 -- some/file/path/file.ext
Combining Jonathan Stray's suggestion to use git-rev-list --before to find the revision at a given date and Show just the current branch in Git:
#!/bin/sh
if [ $# -eq 0 ] || [ "$1" = "--help" ]; then
cat <
Call this script with a date and optionally some file names, e.g.
git-diff-since yesterday
git-diff-since '4 Dec 2012' some/file/path/file.ext
