The default WSL is using bash and even though it supports coloring and customization, the default one is very simple. Since I work with git and I’d like to know which branch I am working on, I’d like to see how to show it in the bash prompt.
The solution (Please notice that I am assuming your installation is using Bash as shell, other shells may be supported, but required some variations in the instructions. )
1- As obvious that it’d sound, first install Windows Subsystem for Linux (WSL)
2- Install Git into the WSL, normally it’s about executing the following command:
sudo apt-get install git
3- Open a terminal Window, and create a file at home. It can be any name. We will use ,git-prompt.sh the content of this file can be download from https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh I tried adding the file content here, but it does not render well 😉
The if statement is optional, however we assume that the file might not be present.
5- Now if you took a look at the file, in the header there is an explanation about how to update a bash or zsh. We will be using bash since we also will support some coloring.
The original script suggest:
PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
However it’s possible in Bash to add support for colors. IF you want to understand better bash command and feature, type the following command in you bash terminal
Here is a sample of the updated PS1
PS1='\[\033]0;$TITLEPREFIX:$PWD\007\]\n\[\033[32m\]\u@\h \[\033[35m\]$MSYSTEM \[\033[33m\]\w\[\033[36m\]$(__git_ps1 " (%s)")\[\033[0m\]\n$'
The final result will show, the
username@hotname directory (branch)
in the bash promt
