Displaying git branch name in prompt does not work in screen

Question

I updated my .bashrc file as follows:

PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$' 

It works just find and I can see my branch name in the prompt. However,when I run "screen" , I get

"-bash: __git_ps1: command not found"

What can be the reason for this?

Answer 1

This blog post explains that you have to add the line source /etc/bash_completion.d/git before you can use __git_ps1.

Here is the full example:

source /etc/bash_completion.d/git   export PS1='\w$(__git_ps1 "(%s)") > ' 

This also enables auto completion for branches.

Using that formatting, your prompt will resemble (without colouring):

~/my-repo(master) >
