This will print a bashprompt similar to this:

(3s) pascal@dell-laptop (master) ~/dev/bashprompt $

where 3s is the runtime of the last command and master is the current git branch.

The displaycolor for the user and hostname can be adjusted here:

USER_COLOR=$BLUE
ROOT_COLOR=$RED
HOST_COLOR=$BLUE

Add this line at the end of your ~/.bashrc:

source /path/to/bashprompt.sh
