git alias's are very handy and powerful.

Frequently I want to look through the log and have a quick view of who did what, so I created this alias

git config --global --add alias.who-did-what 'log --pretty="format:%an - %s"'

the output of which will be something like

chriso - Fixed bug 145
matt - Added some neat feature
wes - fixed one of chris's bugs

...

Enjoy
