Ubuntu 16 default python is almost python 3

Loads of solutions exist, but for changing the system default, alias is not the way to go.

$ update-alternatives --list python update-alternatives: error: no alternatives for python

The Ultimate Git Alias Setup

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.

Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.

The simplest way to add an alias for a specific git command is to use a standard bash alias.

# .bashrc
