Linux

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.

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

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} '

There are two usability tweaks that I would find it hard to live without: (1) red prompt on last-command failure, and (2) highlight what I type, dehighlight output:

Reason for 1 is obvious, 2 is more subtle: it helps my eye scan scrollback and identify what I've typed, which is what I'm scanning for 90% of the time.

Implementations vary, here's how I do it in zsh:

1. PS1='%(?.%K{cyan}%F{white}.%B%K{red}%F{white})XX%b%k%f %(?.%F{cyan}.%F{red})yyy%k%b%F{yellow}%(!.#.$)%f '. Duplication is evil, but AFAIK necessary because the conditional (error check) is %(? and I highlight both parts of my two-part prompt. Suggestions welcome for removing the duplication.
2. zle_highlight=("default:fg=white") (on a Solarized Dark term, where the default fg color is light gray. Adjust to fit your needs).

Fish + OMF.... Work flawlessly

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

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've been using zsh with "oh my zsh". I started using it as it sounded silly and fun compared to bash. Realistically it doesn't really male mich difference. I like the auto complete, but I couldn't say for sure whether it's the shell, oh-my-zsh or what. But I like it.

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.
