[ale] bash commands

[Richard Bronosky]

Okay, I will say that the gem in this discussion is the little know
command: tee

If you ever find yourself using vim to read a file owned by root and then
want to edit it, can do so and write to the file as root using...
:w !sudo tee %

How that words is...
:w !command - writes the content of the buffer as the pipe input to command.
% - is a register that gets substituted with the current file path
tee - see: man tee
