Concept: Bash prompt can run commands every time the prompt is shown
You can easily test changes to PS1 just by setting it. This example will set your prompt to the output from the
date commmand. Example:
# prompt with just the date PS1="$(date) "
Concept: Bash prompts can have colors
Colors are added to bash prompt for ANSI/VT100 with format codes.
echo -e "\033[01;31m\] turn on bright red"
echo -e "\033[00m turn on normal text"

I will use
git symbolic-ref “plumbing” command to get the current branch name.
git symbolic-ref will avoid the “porcelain” command
git branch which meant to be human readable.
Step 2: Add it to the PS1 command
I prefer to add $(parse_git) the system’s default PS1.
Open ~/.bashrc and change from this:
