Proper definition and usage of Git aliases. Note that this feature is provided on Fedora by the supplemental package git-extras.

How to set a regular Git alias:

$ git alias cm commit
$ git alias co checkout
$ git alias b branch
$ git alias cb "checkout -b"

How to set a shell-style Git alias:

$ git alias bu "!git rev-parse --abbrev-ref --symbolic-full-name "@{u}""
