Bash Customizing PS1 Colorize and customize terminal prompt
Example
This is how the author sets their personal PS1 variable:
gitPS1(){
gitps1=$(git branch 2>/dev/null | grep '*')
gitps1="${gitps1:+ (${gitps1/#\* /})}"
echo "$gitps1"
}
#Please use the below function if you are a mac user
gitPS1ForMac(){
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
timeNow(){
echo "$(date +%r)"
}
if [ "$color_prompt" = yes ]; then
if [ x$EUID = x0 ]; then
PS1='\[\033[1;38m\][$(timeNow)]\[\033[00m\] \[\033[1;31m\]\u\[\033[00m\]\[\033[1;37m\]@\[\033[00m\]\[\033[1;33m\]\h\[\033[00m\] \[\033[1;34m\]\w\[\033[00m\]\[\033[1;36m\]$(gitPS1)\[\033[00m\] \[\033[1;31m\]:/#\[\033[00m\] '
else
PS1='\[\033[1;38m\][$(timeNow)]\[\033[00m\] \[\033[1;32m\]\u\[\033[00m\]\[\033[1;37m\]@\[\033[00m\]\[\033[1;33m\]\h\[\033[00m\] \[\033[1;34m\]\w\[\033[00m\]\[\033[1;36m\]$(gitPS1)\[\033[00m\] \[\033[1;32m\]:/$\[\033[00m\] '
fi
else
PS1='[$(timeNow)] \u@\h \w$(gitPS1) :/$ '
fi
And this is how my prompt looks like:
