I’m looking for inspiration for a custom Bash prompt[1]. I’d love to see yours! 😊 If possible, include both the prompt’s PS1
, and a screenshot/example of what it looks like.

I’m mainly using zsh but I have a backup bash prompt that closely mirrors it. It shows the return value of the previous command if it’s non-zero and gives some information about the current git repository if there is one.
retval() { if [ $? -eq 0 ]; then printf "" else printf "\001\e[31m\002($?)\001\e[0m\002" fi } gitbranch() { if type git 2> /dev/null 1> /dev/null && git rev-parse 2> /dev/null 1> /dev/null ; then MODIFIED="" if [[ -n $(git status --short) ]]; then MODIFIED=" M" fi BRANCH=$(git rev-parse --abbrev-ref HEAD) SHORTREF=$(git rev-parse --short HEAD) printf "\001\e[31m\002%s\001\e[0m\002(%s)\001\e[31m\002%s\001\e[0m\002" $BRANCH $SHORTREF $MODIFIED else echo -n "" fi } export PROMPT_DIRTRIM=3 PS1='$(retval)[\001\e[1;95m\002\u\001\e[0m\002@\h : \w $(gitbranch)] \$ ' PS2='> '

Do you have anything to check whether the current directory is under
/media/
or/mnt/
so that you can change the drive letter according to a deterministic assignment?/s
I like Liquid Prompt[1] (A useful adaptive prompt for Bash & Zsh) Examples:
θ70° 2z termight@zone51:~ $ vi .bashrc
θ71° 2z termight@zone51:~/docker/invidious master(+34/-17)* ±
Mine is simple (inspired by Kali Linux, if that’s even correct)
PS1='\[\033[0;32m\]┌──[\t] (\u@\h)-[\w]\n└─$ \[\033[0m\]'
Mine shows the full path and a new line for commands.
It will also print the exit code of the last command in red above the prompt, if the exit code is not 0.
PS1='$(ec=“$?”; if [ $ec -gt 0 ]; then echo -e “\n”[\e[91m]“exit code: $ec”[\e[0m]; fi)\n[\e[92m]\u[\e[38;5;213m]@[\e[38;5;39m]\h[\e[0m]:$PWD\n$ ’
Mine’s really simple; I just make the path bold and yellow:
What I like to do is change the colour depending on the machine I ssh into, e.g. make the path red on my Raspberry Pi.
Ok after viewing your prompts I noticed that mine is kinda lame
PS1='\[\e[1m\][\[\e[92m\]\u\[\e[0m\]@\[\e[96;1;3m\]\h\[\e[0;1m\]]\[\e[0m\] \[\e[1m\][\[\e[38;5;226m\]\w\[\e[39m\]]\[\e[0m\] \[\e[97;1m\]~\[\e[92;5m\]\$\[\e[0m\] '
Note: The “$” prompt flashes like a typical cursor.

Prompt is pretty simple, mainly just adjusted coloring and added a timestamp.
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;36;01m\]\t \[\033[01;32m\]\u@\[\033[01;37;01m\]\h\[\033[00m\]:\[\033[01;36m\]\w\[\033[00m\]\$ '

I use zsh, but my old Bash prompt looks almost the same as my Zsh prompt. Sorry, no screenshot, but here’s the code:
export PS1='\[\033[01;34m\][\[\033[01;37m\] \W\[\033[01;34m\]]\$\033[01;34m\] $(git branch 2>/dev/null | grep '^*' | colrm 1 2)\n\033[01;34m└─>\033[37m '
export PS1="\[\e[31m\][\[\e[m\]\[\e[38;5;172m\]\u\[\e[m\]@\[\e[38;5;153m\]\h\[\e[m\] \[\e[38;5;214m\]\W\[\e[m\]\[\e[31m\]]\[\e[m\]\\$ "
Mine is just status(if not zero) and wd
My bash prompt is just me copying the prompt I have set on fish.
# Prompt green=$'\e[38;5;2m' bright_red=$'\e[38;5;9m' bright_green=$'\e[38;5;10m' reset=$'\e[0m' prompt_command() { local exit_status=$? if [[ $exit_status != 0 ]]; then exit_color=$bright_red exit_prompt=" [$exit_status]" else exit_color=$bright_green exit_prompt="" fi } PROMPT_COMMAND=prompt_command PS1='\[$green\]\w\[$exit_color\]$exit_prompt\n❯ \[$reset\]'
I have a small issue with this prompt though. Sometimes the ❯ ends up turning white for some reason.
