prompt

bash prompt

My bash prompt has been with me for years, but I didn't build it myself. I started out with a copy from paulirish/dotfiles - which at the top of the file mentions that it was based on a copy of the prompt from gf3/dotfiles.

Installation

Source the prompt.sh file in your .bashrc file.

Walkthrough

At it's most basic, the prompt will just show you the basename of your current working directory. If you're in $HOME:

 ~ $

If you're in /home/gustav/Projects:

 Projects $

I prefer the prompt not getting too long, so I don't show the whole path in there - but just enough of it that I get an idea of where I am at.

git

If the directory your in is part of a git repo, the prompt will show you what branch you're currently on:

 my-project on master $

 my-project on feature/new-stuff $

If the status of the git repo is unclean, the refname will have an asterisk tagged onto it.

 my-project on feature/new-stuff $ echo 'foo bar' > newfile.txt
 my-project on feature/new-stuff* $

node versions

If you are in a folder with a .nvmrc file, the prompt will show the node version as part of the prompt in red text, if the node version is not the one listed in .nvmrc.

 my-project $ node -v
6.0.0
 my-project $ echo 8.11.3 > .nvmrc
 my-project node v6.9.4 $ nvm use
Now using node v8.11.3
 myproject $

The node version is ONLY displayed when the active node.js version is not the same as the one listed in .nvmrc.

root

If you get a super user shell, the indicator will change from a friendly green $ to a red and scary #.

 foo $ sudo -s
 foo #
