(Mac) -bash: __git_ps1: command not found

Question

I\'m trying to change my command promt in terminal. I keep getting the error:

-bash: __git_ps1: command not found

I\'ve tried it just by typing

Answer 1

This one worked for me, and it has colored git output and an indicator in the prompt whether files have changed / been added, right baked into it:

GIT_PS1_SHOWDIRTYSTATE=true

. /usr/local/Cellar/git/1.8.5.2/etc/bash_completion.d/git-completion.bash
. /usr/local/Cellar/git/1.8.5.2/etc/bash_completion.d/git-prompt.sh

PS1='\[\033[32m\]\u@\h\[\033[00m\]:\[\033[34m\]\w\[\033[31m\]$(__git_ps1)\[\033[00m\]\$ '

Be sure to use the correct path! I used homebrew to install git, use brew list git to get the path to your current installation.

Would be nice not to use a hard coded path, but don't know how to get the path to the current installation.
