A question came up about setting the Git editor to a bash function, which I could not figure out. I was, however, able to set the Git editor to a bash script. As a proof of concept, here is a bash script to randomly choose an editor (nano or vim) when using Git.
git log
Improve Git Log
By default the output of ‘git log’ is not nearly as useful as it could be. By creating a new command ‘git lg’ that uses some of the options available to ‘git log’, we create a much more useful command.
