Bash Prompt

I really like the Bash prompt I use now. It’s just a $ followed by a space. The $ is green if $? is zero and red otherwise. If the current working directory is in a Git repository, the name of the checked-out branch appears before the $ in blue with a space in between. Red, green, blue. Simple and elegant. It’s great. function customprompt { EXITSTATUS="$?" BOLD="\[\033[1m\]" RED="\[\033[1;31m\]" GREEN="\[\033[1;32m\]" BLUE="\[\033[1;34m\]" OFF="\[\033[m\]" BRANCH=$(__git_ps1 | tr -d ‘( )’) if [ ! -z $BRANCH ] then BRANCH="$BRANCH " fi if [ “${EXITSTATUS}” -eq 0 ] then PS1="$BOLD$BLUE$BRANCH$GREEN$$OFF " else PS1="$BOLD$BLUE$BRANCH$RED$$OFF " fi PS2="${BOLD}>${OFF} " } export GIT_PS1_SHOWDIRTYSTATE=1 export PROMPT_COMMAND=customprompt
