Me neither. It's easy on Debian. (sunrat dodges hurled stones).

 

ps. I love the irony of your incorect speling.

Hello,

 

A bit dated, but this decade-old thread on Slashdot might be of interest: What Does Your Command Prompt Look Like?

Good one Aryeh. There be some nasty but funny posts there, eg.:

alias rm="echo I\\'m sorry Dave, I\\'m afraid I can\\'t do that"

[V.T. Eric Layton 6,697]

Wow! 2001. I hadn't even heard of Linux then.

[crp 823]

Is that the page that had the infamous Snoopy prompt? It left the user with only 1 viewable command line and took up all the memory allocated to the environment space.

[wa4chq 416]

Reviving the dead....lol

Here's my latest......using ZSH.....I'm also including todays weather.

[saturnian 657]

Wow! I like short and simple for my bash prompts:

 

user1[~]$

 

PS1='\[\e[1;32m\]\u[\w]\\$ \[\e[0m\]'

 

[V.T. Eric Layton 6,697]

Hmm... that is short and simple. I'll bet you're a vanilla ice cream type, huh?

[wa4chq 416]

lol....the screenshot I posted shows the whole screen including my prompt.....the prompt I'm using is just a single line! lol I included the local weather out of kindness...lol

This is from my work laptop:

 

[wa4chq 416]

PS1="[%w] $fg[green]%n %~ $fg[white]--> "

Edited July 24, 2019 by wa4chq

[saturnian 657]

PS1="[%w] $fg[green]%n %~ $fg[white]--> "

 

Does this work only for ZSH? I tried it here (using BASH) and it gives me this prompt, all in white:

 

[%w] [green]%n %~ [white]-->

[securitybreach 11,431]

Main home rig prompt:

 

[securitybreach 11,431]

PS1="[%w] $fg[green]%n %~ $fg[white]--> "

Zsh does not use that syntax in it's config. Here is my ~/.zshrc:

# Set name of the theme to load.

# time that oh-my-zsh is loaded.
ZSH_THEME="evan"

# Uncomment the following line to disable bi-weekly auto-update checks.

# Uncomment the following line to enable command auto-correction.

I believe so, only for zsh. If I try using bash prompts with zsh, they don't work. There are plenty of sites for pimping bash. Here's one...https://www.maketecheasier.com/customise-bash-prompt-linux/

Nice. I use to use "oh-my-zsh"....pretty slick....lot's of cool prompts to choose from.

vtop.....looks interesting......gotta look into that one.

well, I checked into vtop for MX-18 and Slackware....no dice. Guess I'll settle for nmon or htop.

I used the above site to create a new bash prompt. Blue for me as a user and red as root. 

 

[securitybreach 11,431]

Nice but why xterm? It's the least customizable prompt there is.  Plus you should switch from bash to zsh, it will make your terminal usage 110% better.

Hmmm I only use the cli a little. This is probably why I have never changed, from the wiki,

Although Zsh is usable out of the box, it is almost certainly not set up the way most users would like to use it. But due to the sheer amount of customization available in Zsh, configuring Zsh can be a daunting and time-consuming experience.

 

An I have looked at other terminals but none of them seemed to offer much extra from xterm. Or the benefits were not large enough for me to do loads of reading up on. I did trial a really fancy one ages ago, I liked the E17 one but it borked on an update, a lot of E17 stuff did back then.

An I did try out Fish and ran it for a while.

 

Like I said I only play with the cli now and then, maybe I'll dive in and change at some point but then again ----

[securitybreach 11,431]

Zsh has lots of benefits including tab completion of commands (with options) and filenames as shown by this quick video I recorded: https://www.youtube.com/watch?v=zt7PNAr9vwI

 

Oh-my-zsh is a framework for zsh which provided a lot of prebuilt themes as shown here: https://github.com/ohmyzsh/ohmyzsh/wiki/themes and a bunch of plugins available as well https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins

 

Just install oh-my-zsh-git from AUR (or via git) and type zsh in a terminal to start zsh and if you want it as your default for terminals, follow this  https://wiki.archlinux.org/index.php/Command-line_shell#Changing_your_default_shell

Advantages that I appreciate:

1. Much easier prompt definitions. Particularly dynamic/multine prompts.
2. Right Prompt? Yes, thank you!
3. Awesome set (more comprehensive than BASH) of Auto Completions are much faster and smarter (e.g. case insensitive completion, smart defaults)
4. Path Expansion is pure win. (cd /v/w [tab] == cd /var/www)
5. Path Replacement is pretty cool also.
6. Spelling Correction (setopt correct) is mighty awesome for me.
7. oh-my-zsh - Large, community driven framework for all sorts of bells and whistles.
8. The Zsh Line Editor ... just google it
9. Key Bindings? Yes, thank you!
10. Globbing is awesome (Extended, inline, just wow!)

I still haven't bothered to switch from bash to zsh! I think I've done a couple of installations now where the distro's default was zsh and I simply switched it to bash. zsh looks cool, maybe I'll try it out.

 

As for xterm, I rarely use that but I'm not very particular about terminal emulators -- often, I just stick with the default.

Neat, that looks pretty interesting.

 

I have had a good read up from your links and all over the net. I'll let teh info settle in the grey cell for a while. Interesting.

Bash $PS1 Generator2.0

 

Just another easy to use prompt modifier.

[abarbarian 3,455]

Latest addition to me bash prompt,

 

 

This is the entry I put in my ./bashrc. Do " source ~/.bashrc " to make the change permanent.

PROMPT_COMMAND="echo -n $(tput  bold) $(tput setaf 6)Put brain in gear befor pressing enter"
#unset PROMPT_COMMAND #use this to go back to normal

When starting out you can use the command in a terminal and fiddle about with it till you get it right with no damage done as it goes away when you close the terminal. Took me quite some time before I could get  colour and bold together. I tried loads of different combinations and eventually found the answer tucked away on some obscure site whose link I have misplaced.

I was originally motivated to pursue this time waster by this site,

 

https://tldp.org/HOWTO/Bash-Prompt-HOWTO/x264.html

 

Next timewaster is to put the warning in red and blinking in my root prompt.

So much easier to do the same thing with Oh-My-Zsh

Original boring xterm with neofetch,

 

 

Several hours later after serious searching on the net,

 

 

Amazing what innovation a small virus can stimulate.

Looks great
