git lol - an alias to Git that shows the commit graph in a pretty format

log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit

To configure as an alias git lol:

git config --global alias.lol "log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)&lt;%an&gt;%Creset' --abbrev-commit"
