That's just the PS1 environment variable. Throw it in /etc/profile or /etc/bashrc I think. If you want it just for one user then I think it's ~/.bashrc

Hope that helps. I think there's a bash howto on www.linuxdocs.org

If you want a pretty sick tutorial on setting the bash prompt, the man himself, drobbins, wrote a cool one that on the ibm site here
http://www-106.ibm.com/developerworks/linux/library/l-tip-prompt.

PostPosted: Sun Jun 23, 2002 5:16 am    Post subject: Extra informative Bash prompt Reply with quote

I've got a bash prompt that I've been using for quite awhile now, and that others that I've shown it to often want to make use of, so I thought I'd offer it up here, too.

It's a 3 line prompt, but I find it provides me almost every bit of info about my current environment I need or want at a glance.

Note: The following assumes a black terminal background. If you're using a white background, you'll need to adjust the color codes to be more visible (as can be seen in the example prompt shown below).

Code:
PS1="\n\[\033[35m\]\$(/bin/date)\n\[\033[32m\]\w\n\[\033[1;31m\]\u@\h: \[\033[1;34m\]\$(/usr/bin/tty | /bin/sed -e 's:/dev/::'): \[\033[1;36m\]\$(/bin/ls -1 | /usr/bin/wc -l | /bin/sed 's: ::g') files \[\033[1;33m\]\$(/bin/ls -lah | /bin/grep -m 1 total | /bin/sed 's/total //')b\[\033[0m\] -> \[\033[0m\]"




This ends up producing a prompt such as the following:
Code:

Sun Jun 23 00:33:58 EDT 2002
/usr/src/linux
wont@calvin: pts/3: 23 files 3.8Mb ->


where:
Line 1-- current date and time
Line 2-- current working directory
Line 3-- username @ host: console number: # of files in directory total size of directory on disk ->

Hope this is of interest to someone out there. :-)

Will

I've not botherd to relearn prompt code. I don't need all that info, but this certainly makes
it easier to learn :D

Thanks for the tip.


EDIT:

Here's a bash prompt that shows battery status on a laptop. Needs apm tools / kernel support available (and awk).

Code:
PS1="\`apm|awk '\$5~/%/{print \$5}\$6~/%/{print \$6}'\` [\\u@\\h:\\w] \\$ "


.. and this is what it looks like

Hope you don't mind, I edited your prompt to produce mine. I removed the time, # of files
and dir size. Changed the look a tiny bit, will probably change colors in the future.
Code:
PS1='\n\[\033[32m\]\w\n\[\033[0m\][\[\033[1;31m\]\u@\h \[\033[1;34m\]$(/usr/bin/tty | /bin/sed -e '\''s:/dev/::'\'')\[\033[0m\]] \[\033[0m\]'


/usr/portage
[user@hostname pty/s0]

Again, meant for a dark background. 1st line is current directory path. 2nd line is user
and hostname with terminal enclosed in [ ] (Hard to see here, they are white).

About 5 years ago. I borrowed the sets from a bashcolor script and did something similar.

[This is from my /etc/profile file]

# Color Variables for Prompt
GRAD1='\333\262\261\260'
GRAD2='\260\261\262\333'
YLOBRN='\[\033[01;33;43m\]'
WHTBRN='\[\033[01;37;43m\]'
REDBRN='\[\033[00;31;43m\]'
REDBLK='\[\033[00;31;40m\]'
PPLBLK='\[\033[01;35;40m\]'
WHTBLK='\[\033[01;37;40m\]'
NONE='\[\033[00m\]'
HBLK='\[\033[00;30;30m\]'
HBLU='\[\033[01;34;34m\]'
BLU='\[\033[00;34;34m\]'
YEL='\[\033[00;33;33m\]'
WHT='\[\033[01;37;37m\]'
PRPL='\[\033[00;34;35m\]'
RED='\[\033[01;31;31m\]'
NORM='\[\033[01;00;0m\]'

export GRAD1 GRAD2 YLOBRN WHTBRN REDBRN REDBLK PPLBLK WHTBLK NONE HBLK HBLU BLU YEL WHT PRPL RED NORM

# Prompt Settings
if [ `/usr/bin/whoami` = 'root' ]
then
if [ "$SHELL" = '/bin/bash' ] || [ "$SHELL" = '/bin/sh' ]
then
PS1='\n'$WHT'*'$NONE'['$HBLU'\u'$WHT'@'$HBLU'\h'$WHT':'$HBLU'\W'$NONE']'$NONE' '
PS2='\n'$WHT'*'$NONE'['$HBLU'\u'$WHT'@'$HBLU'\h'$WHT':'$HBLU'\W (2)'$NONE']'$NONE' '
fi
else
if [ "$SHELL" = '/bin/bash' ] || [ "$SHELL" = '/bin/sh' ]
then
PS1='\n'$NONE'['$HBLU'\u'$WHT'@'$HBLU'\h'$WHT':'$HBLU'\W'$NONE']'$NONE' '
PS2='\n'$NONE'['$HBLU'\u'$WHT'@'$HBLU'\h'$WHT':'$HBLU'\(2)'$NONE']'$NONE' '
fi
fi

================

[user@host:directory]

What this does is make a very nicely colored prompt that looks well at home with both white and black backgrounds (but probably looks better with black background). And the added feature of when your root, it sets your prompt with a star in front of it like this.

*[root@host:directory]


I am in a habit of having so many sessions running, that I tend to forget which one is root or not, and just grab the session and start working. its very bad to test untested or foreign code as user root, so this helps me to make sure i do not trash a system by running bad/rogue code.

It is also very bad to intend to reboot a remote client and forget that you are in the
server terminal. Fortunately it was during a setup phase :D

There exists a program called "bashish" which allows you to switch between a lot of prompts (from the best to the ugliest ones):
http://bashish.sourceforge.net/

There is no ebuild as far as I know, maybe I'll write one someday...

Sorry for being such a n00b, but where do I put this? In ~/.bashrc ?

EDIT: Did some research and found out that this should be in /etc/profiles .. :)

Thx. :) This is my one now:
PS1='\[\033[0m\][\[\033[1;36m\]\w\[\033[0m\]] \[\033[0m\]'

Looks like this:
[/usr/src/linux]

(only good for black background of course)
and that's everything I need =) simplicity rules.

Hmm, I put this in /etc/profile but it only works on tty, not in xterm. Can anyone tell me what I have to do to get it working in X?

Try putting it in your ~/.bashrc.

(If i recall, /etc/profile is read only if its a login shell, not an interactive shell (which xterm things are)... ~/.bashrc is read for both...)

When you mention putting that prompt in ~/.bashrc do you mean for each user, for root only, or what ?

Is there one file location that works for all users (including root) and whether it is X or not.

~ translates to 'home directory'. So that would be for 'each user'.

/etc/profile works for all not including X.

You might investigate 'man bash' for more info, though I'm not aware of a single file for all.

You could also edit the .bashrc in /etc/skel so when new users are added and it uses that directory as the template, they get the new prompt.

-Ted


Most (if not all) terminals under X (xterm, gnome-terminal, Konsole, rxvt, etc) support the -ls option that specifies the terminal should run as a "login shell". IIRC, this will cause /etc/profile to get read and executed... If I'm correct, putting your prompt in /etc/profile would then affect all users who run shells that read /etc/profile.
