Use hub
hub is a replacement for git, well it is actually just a command line wrapper, which makes your work with GitHub easier.
hub can be safely aliased as git, so you can type $ git
in the shell and have it expanded with hub features.
Prior to aliasing:
$ hub --version
git version 2.25.0
hub version 2.14.1
$ git --version
git version 2.25.0
Aliasing:
$ alias git="hub"
$ alias | grep hub
alias git='hub'
After aliasing:
$ hub --version
git version 2.25.0
hub version 2.14.1
The alias should be put in your .bash_profile or equivalent.
