Situation: Some commit (on master, but not necessarily head of master) has broken things, but it's a big commit and it's not clear what part broke things.

% git checkout master
% git checkout -b bisect-branch
% git revert <offending commit>

(test here to make sure reverting fixed your problem)

% git bisect start

Why I love zsh (and hate being forced to use bash)

• Smarter completion. A few examples:
• context sensitive -- if you have file "name1" and directory "name2", "cd nam<TAB>" completes to "name2/"
• "tar xf <TAB>" completes to tarballs only. "unrar x <TAB>" completes to RARs only. etc.
• rsync / scp completion: "rsync host:anything/<TAB>" shows you files on host under anything/
• also works with rsync:// URLs
• SSH host completion from ~/.ssh/config & ~/.ssh/known_hosts
• lots of other smart completions: Rake tasks, git commands & SHAs, dpkg packages, dash-options for most commands, etc etc.
