[Question] Which shell prompt do you use and why?

I use plain old bash with the plain old .bashrc that ships with Debian. I’ll bolt on a git-branch-aware function into the prompt here and there, but that’s about it.

Why? I ssh into a few dozen machines most days and my shitty little lizard brain can’t deal with everything being different on each box. So as much as I appreciate zsh, powerline plug-ins, all that glitzy stuff, I’ll be a late adopter when it comes to plain old Debian stable…

Fish, with Starship. It does everything I need it to, completely unmodified. In comparison, zsh barely reached feature parity with a dozen plugins, and I just don't want to spend my time on that

Yes, I use starship with nushell.

I use Zsh with the Oh My Zsh! framework, and I use a different theme depending on which subuserland I’m in, by customising ~/.zshrc. For example, I use the gentoo theme on Debian and its derivatives, agnoster on NixOS, darkblood on Arch, strug for Mageia, apple on my macOS device, aussiegeek on FreeBSD, and gallifrey on OpenBSD. Different themes helps me remember which package manager to use and which distro-specific commands will work.

I'll send some screenshots in a bit, when I boot up my PC.

I like Zsh because of its tab completion and command history. I also quite like its plugins.

Before anyone asks, I have tried Fish before, and I prefer Zsh. I have tried configuring Bash before, and I prefer Zsh. I have played with Ksh and Tcsh on BSD, and I prefer Zsh. I used PowerShell a long time ago, and I prefer Zsh.

I use fish + tide

I tried zsh+p10k before fish+tide, but zsh felt annoying in subtle ways that weren't fixable with (existing) plugins, so I switched back to fish, but installed tide to mimic my previous p10k theme.

I designed this prompt shortly after I switched to Linux, I've been using it for a while, it has a few features like putting the exit code if it isn't 0, changing the hostname color if its detected that you are over ssh, changing the directory color to red if it isn't writeable, changing the prompt color to red if your euid is 0, and instead of printing I have no name! when your user does not have an entry in the passwd file, it will just print your uid in red. I also have a version that I wrote in C that works the same way with a subsitution shell, but it was harder to sync across all my devices when I made a change, so I rewrote it in posix shell that could be synced with just my .bashrc and work almost anywhere.

I don't know how to post a screenshot, sorry for the long paragraph, but here is the source code, feel free to share or do whatever with it!

I'm on the boring side...

PS1="% "

I like it though, it gives me more room for commands !

I just use the default fish without any modifications.

To be fair, I don't use the terminal that often.

Even for my homeserver, I access most stuff (containers, updates, etc.) graphically with CasaOS (a web interface), and as a more "casual" PC user, I work with the tools given by my DE. I don't do much fancy stuff.

And when I really need the CLI, fish is alright for me. It's simple, has sane defaults, and feels (thanks to the automatically activated spell check and completion) very efficient for me.

Bash isn't bad, but feels a bit lackluster. Zsh may be better, but requires too much configuration for what it's worth for me.

I'm old school, I use Bash and do the basic " [user@hostname working-directory]$ " but there's a newline before the first bracket so there's always a line break and an indent after STDOUT so I can tell where the command output ends if it's huge. I also tend to colorize it a bit.

I've tried ZSH and I like it, but as a Linux System Engineering overseeing thousands of servers, they all use Bash, so that's what I've stuck with as well.

I tried oh-my-bash with some fancy theme, but went back to plain old bash from my distro since suggestions for autocomplete had suddenly started to lag. Went back to default and it's as quick as ever to suggest.

I'm not willing to trade efficiency for bells and whistles

I edited my PS1 variable

Vanilla zsh prompt. I had a thing that told me which git branch I was on for a while but my editor tells me that so I decided I didn't need it

I customize the shell prompt in the PS1 variable. Its unpleasant to work with that unreadable language, but I do that once for years and I reuse it across distros.

Fish shell with a built-in theme

Currently, I use starship, but I have considered switching to a regular PS1 or similar setup, it's just that I can't get the colours right when using PS1.

Powerline10k with Nerd Fonts, all the way.

Bash with blesh And nano-syntax-highlighting

Standard Bash with a twist:

[ /full/path/~-prefixed where possible ]
 user@short-hostname $ _

(Underscore = cursor, not part of prompt, in case that's not obvious.)

It's similar enough to the most common Bash prompt that I don't feel totally alienated on a different system but different enough to be unique / useful.

The carriage return is deliberate. Paths can often get quite long in my homedir (if not other places), even with the ~ abbreviations. I can't imagine anyone likes starting to type a command more than halfway across a screen because of a long path; this was my solution.

The spacing is deliberate too. The brackets are hard to distinguish without the spaces either side of the path. On the second line, the 1-char indent and the spaces around the obligatory $ were the layout I found most pleasing.

There are embedded colour codes, but it's designed so that it looks fine without them, just in case.

As for other configuration, I use whatever comes with the distro I'm using, especially any command-completion, etc.

Oh-my-zsh. Looks like somebody needs to try and convince me on fish though (happens every so often).

I’ve used powerline-go for a long time now. The modules I use are, modules = ["cwd" "ssh" "dotenv" "nix-shell" "gitlite" "exit"]; (from my home-manager config). It tells me everything I need, and looks pretty, too. Maybe I should mix it up for some variety, but I do like the info it provides.

I used to use starship with zsh. It's pretty good, I did write my configuration from scratch but kept it really short and barebones. The configuration is fairly nice and easy so you won't feel overwhelmed really.

Although at this point I just use bash with the default prompt in Fedora. Couldn't be bothered setting it up again(even though it takes like 5 minutes) because I rarely use the cli lol.

custom, baby! based off starship, but half the latency

.bashrc:

# Prompt
# "Make it simple, just the dollar sign"
# "Say no more, fam"
# - if error code is not 0, then prepend [N] where N is the error code
# - if user is root, use red and #
blue='\e[34m'
red='\e[31m'
bold='\e[1m'
reset='\e[0m'
PS1='$( status=$?; [ $status -ne 0 ] && echo "[$status] ")\['"$blue""$bold"'\]$\['"$reset"'\] '

if [[ $EUID -eq 0 ]]; then
  PS1='$( status=$?; [ $status -ne 0 ] && echo "[$status] ")\['"$red""$bold"'\]#\['"$reset"'\] '
fi

.inputrc:

# vi mode, change to 'emacs' here if you prefer
set editing-mode vi

# vi INSERT prompt
set vi-ins-mode-string "\1\e[30;44m\2 INS \1\e[0m\2 "

# vi NORMAL prompt
set vi-cmd-mode-string "\1\e[30;47m\2 NOR \1\e[0m\2 "

When I hopped on the home manager train I enabled starship (since it was just a couple lines to add) and I'm very happy with it. It has a couple small things out of the box that I really want. Mostly, its trimming my path so it doesnt take the full width of my terminal. I have it set so it only prints the lowest 3 directories and it wont print any directory higher than the current git repo Im in. IMO i hate all the little emojis but that was very easy to remove/disable. Its a very clean experience, and straightforward config (toml if not using nix).

EDIT: here's a pic of the path trimming. This is about as complicated as it gets. Also, I'm using catpuccin color scheme in urxvt.

I used variations of the same homecooked bash prompt ever since my FreeBSD days 25 years ago, up until Parrotsec made me realize that a prompt doesn't have to be confined to one line.

So now I use:

username@host:/full/path #
:

...with a bunch of colors and special characters to make it more readable at a glance. That colon represents the input line.

To conserve some space I only used last part of CWD before, but now that it's multiline I can use the full path, making it easier when I need to copy-paste an scp-friendly path, as I'm usually working across a bunch of different usernames and hosts.

I made two go programas to make my prompt

It's a pwd with user customization, like colors and names, an inline git status and then the exit code of the last command

inline git status

customizable pwd

I'm in the process of remaking them tho, since they used a shitty go preprocessor that I no longer maintain.

I use oh-my-posh (on a windows machine) with a custom theme that tells me some git info and a few other things. But when I'm in my Linux machine its a vanilla zsh

zsh with prezto and default prompt. I've customized a bit, but the only change I made to the prompt was to replace "..." (three periods) with "…" (ellipsis unicode) since that makes it more compact with a monospace font. I really like the async loading of git status, so I don't have to wait for the command to run before the prompt prints.

Color green for normal users and red for root. then date, hostname. and finally time of day

I used to color my prompt depending on which server I was connected to (ssh), and a different color scheme for prod, dev and local. But that was a long time ago and the script is buried somewhere, also I don't stay ssh'd to nearly as many places as I did back then. But I did like it, I'd use it now if I had it.

Zsh and Starship.rs on top with few extra minor things. I like my shell fast and clean.

Custom PROMPT variable in my .zshrc. Similar format in .bashrc, but uses PS1 instead.

Prompt shows git branch, italics and custom colors/characters. Shows a hanging arrow on a newline (i know, wasted newlines are blasphemy to some, but I like it).

Renders nicely in my custom compiled suckless terminal using monospace font.

PROMPT='%B%F{blue}[  %B%F{white}$(tput sitm)'%1~'$(tput sgr0)$(tput bold)%B%F{blue}]$(tput sitm)$ %B%F{white}$(tput setaf 5)${vcs_info_msg_0_}%B%F$(tput sgr0)$(tput setaf 4)$(tput bold)
└─>%B%F{white} '

I'm using guake

I like that it's just the F12 key away then F11 to expand to full window. Supports multiple tabs.

Anyone using guake?

I use bash-it and set it to powerline theme

Fish + OMF.... Work flawlessly

I use budspencer theme on fish. https://github.com/oh-my-fish/oh-my-fish/blob/master/docs/Themes.md#budspencer-theme It looks cool and yellow, which I like. I prints the path on the far right and parent folders are printed only with initial letter, so it doesn't take 2 lines in the shell and it ends up pretty short. It also has git integration and some budspencer exclusive commands to perform some cools actions, I don't care about and I have never used. Also, I like that command errors are displayed as ✔ or ✘ on the next prompt. It also prints the time the last command has been running. I use vi keybidings, so prompt color changes when I change the mode feel cool. I would also like to have the execution time for every command, but I have another theme for that I don't remember the name of on my work machine.
