Many people know that you can add the Git branch name you are currently working in to the end of your command prompt but did you know that you can also have the command prompt notify you if you have any untracked of modified files?

I have created this post with linux in mind but I’m sure you can Google what to do if you have a different OS

First place the following in ~/.bashrc so that .bashrc can read my script.

# Include my very own git parse type function :-)
source ~/.GitParseStatus.sh

Then I update the PS1 variable (the command prompt text) to output the result of the script

export PS1=”\n${debian_chroot:+($debian_chroot)}${RED}\u@\H ${YELLOW}\A ${BLUE}\w \$(gitParseStatus)${NORMAL}\n$ ”

It’s the \$(gitParseStatus) bit that works the magic we want.

and then of course I have the script which I save as ~/.GitParseStatus.sh (don’t forget to make the script executable with

chmod +x ~/.GitParseStatus.sh

#!/bin/bash
#function get_out() {
# log $1
# return
#}
#
#function log() {
# echo '* '$1
#}
#
#
#if [ $1 = "--debug" ]; then
# DEBUG=true
# echo
# echo "==========="
# echo "Debug is on"
# echo "==========="
# echo
#fi

I hope it is of use to some of you and if you have any problems you know where I am.
