zer0prompt - a Phil!'s ZSH Prompt alternative for BASH users

Zer0 · 2009-11-09 03:31:35

Story:
Quite awhile back when I discovered Phil!s ZSH Prompt via one of the Screenshots threads. I wanted a prompt like that but I don't use ZSH, I'm a bash user. So I looked for something with similar options and looks for bash without any luck. I tried Bashish but I felt that there was too much extra going on for what I wanted. You know what they say! Want something done right, do it yourself!

So I created zer0prompt for myself, used it for a couple years and now I feel like sharing it . It has some features from Phil!'s prompt, similar looks to Bashish's bluesteel theme,
I just finished going over the code for public release. I cleaned up the code, added some features, a few user options and this is the result...

Screenshots:

Features:
- a TERMWIDE prompt, fills the width of the terminal no matter how wide.
- 2 line prompt
- following info is always shown = user, host, current tty, working directory, time, user identifier.
- truncates the shown working directory when it's wider then the terminal.
- shows /home/user as ~
- continuation prompt.
- when logged in as root user, display info in red (visual reminder).
- displays the exit code when a command fails.
- sets xterm/rxvt terminal titles (shows username, WIDTHxLENGTH, and directory)
- user selectable = colour themes, info colours, time format, and line graphics.
- user can manually set "no colour mode" and/or "safe line graphics" mode
- very easy to install without making a mess of your .bashrc
- tries not to pollute your bash environment

Usage:
1) save the code in the next post as file .zer0prompt inside your home directory
2) edit your .bashrc , comment out the PS1 line, and add the following

source ~/.zer0prompt
zer0prompt
unset zer0prompt

3) repeat for root if you want to display the info in red when you su to root.

Thanx a lot for sharing

PingPing · 2009-11-11 07:26:00

Saw this on November screenies. Great work and thanks for sharing it.

tidalwav1 · 2010-01-14 03:09:23

This appears to work great...

...as long as it's not running inside tmux (similar to GNU Screen)! :'(

Screenshot outside tmux:

Screenshot inside tmux:

You can see in the second screenshot where the commands/cursor appear in relationship to the prompt.

If I detatch from and reattach to tmux, the cursor jumps around/switches positions sometimes, but never displays in the correct place.

This is obviously a very sweet Bash prompt and I appreciate that you've made it available, but...any suggestions/thoughts for getting it working inside tmux?

Thanks!

call me wierd but I dont understand how to get it to work for root........ followed instructions and all is fine except root doesnt show properly thanks........
pretty sweet.

sorry.......
more specifically if I do it then yes it turns red but I lose the color for things like folders and what not if say I do su and then password then "ls" everythings white
instead of blue for folders and what not.

thanks

Add this to your ~/.bashrc:
alias ls='ls --color=auto'

your the bomb.........

I know this is a really old post but Im experiencing an issue with a new install using this script.

?????jricide@jricide:4???????????????????????????????????????????????????????????????~???

as you can see question marks instead of -------

so how might I fix that?

thanks

WonderWoofy · 2013-07-09 23:35:04

It works for me in bash... did you follow the instructions?

splippity · 2013-07-10 03:13:20

yes I copy and pasted the entire script into a file and then linked it

shows up the same no matter what I use it in: konsole, xterm or whatever

always has the ?????????? instead of -------------

ok I was looking at the script and it looks like they used the following symbols and I have no idea what I would need to install to get bash to recognize them:
## set line graphics to use
zg1="─"; zg2="┌"; zg3="└"; zg4="┤"; zg5="├"; zg6=">"; zg7="|"
#zg1="-"; zg2="+"; zg3="+"; zg4="|"; zg5="|"; zg6=">"; zg7="|"

any help would be appreciated thanks

jasonwryan · 2013-07-10 03:32:35

They are unicode symbols: yout $TERM needs to support them and you also have to have your locale set correctly.

This isn't a support thtread, though so you should start a new thread with information about both of the above on your machine.
