set PS1 variable in your .bashrc in ~/home/user directory

Code:

#---------------------

# Define a few Color's

#---------------------

BLACK='\e[0;30m'

BLUE='\e[0;34m'

GREEN='\e[0;32m'

CYAN='\e[0;36m'

RED='\e[0;31m'

PURPLE='\e[0;35m'

BROWN='\e[0;33m'

LIGHTGRAY='\e[0;37m'

DARKGRAY='\e[1;30m'

LIGHTBLUE='\e[1;34m'

LIGHTGREEN='\e[1;32m'

LIGHTCYAN='\e[1;36m'

LIGHTRED='\e[1;31m'

LIGHTPURPLE='\e[1;35m'

YELLOW='\e[1;33m'

WHITE='\e[1;37m'

DARKGRAY='\e[01;30'

LIGHTGRAY='\e[00;37'

NC='\e[0m'              # No Color

# Sample Command using color: echo -e "${CYAN}This is BASH



PS1="\[\033[35m\]\[\033[36m\]\w\n\[\033[0;31m\]\u@\h\[\033[1;34m\] ~\[\e[1;32m\]> \[\e[m\]\[\e[0;37m\]\[\033[0m\]"

The above text code will give you the desired prompt!

Hi,
Since you want to modify '.bashrc' then you could setup a .bashrc & .bash_profile for your user. Just modify the PS1 to suit;

Code:

sample .bash_profile;

Code:

 

 ~$ cat .bash_profile

 # .bash_profile

 #08-30-06 12:21

 #

 # Source .bashrc

 if [ -f ~/.bashrc ]; then

         . ~/.bashrc

 fi

Code:

 sample .bashrc;

 :~$ cat .bashrc

 

 #.bashrc

 #08-30-06 12:20 

 

 # Add bin to path

 

 export PATH="$PATH:/sbin:/usr/sbin:$HOME/bin"

 

 #export PATH="$PATH:$HOME/bin"

 

 # Dynamic resizing

 shopt -s checkwinsize

 

 # Custom prompt

 #PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

 

 #08-29-06 11:40

 

 if [ `id -un` = root ]; then

   PS1='\[\033[1;31m\]\h:\w\$\[\033[0m\] '

  else

   PS1='\[\033[1;32m\]\h:\w\$\[\033[0m\] '

 fi

 

 #

 # Add color

 eval `dircolors -b`

 

 # User defined aliases

 alias cls='clear'

 alias clls='clear; ls'

 alias ll='ls -l'

 alias lsa='ls -A'

 alias lsg='ls | grep'

 alias lsp='ls -1 /var/log/packages/ > package-list'

 alias na='nano'

 alias web='links -g -download-dir ~/ www.google.com'

 

 #08-29-06 11:50

 

 #To clean up and cover your tracks once you log off

 #Depending on your version of BASH, you might have to use

 # the other form of this command

   trap "rm -f ~$LOGNAME/.bash_history" 0

 

 #The older KSH-style form

 #  trap 0 rm -f ~$LOGNAME/.bash_history

The .bashrc is very useful!
Bash Reference Manual & Advanced Bash-Scripting Guide along with Rute Tutorial & Exposition should provide additional help.

ok, to be honest i don't understand how the provided codes can change bash to user@... please can someone run it by me as it seems this only colourises the terminal to which i have got it coloured already."god i've got to use to babysitting distro's like ubuntu, lol"

^Look carefully at the line above, this will help you understand-

Quote:

When executing interactively, bash displays the primary
prompt PS1 when it is ready to read a command, and the
secondary prompt PS2 when it needs more input to complete
a command. Bash allows these prompt strings to be cus-
tomized by inserting a number of backslash-escaped special
characters that are decoded as follows:

\a an ASCII bell character (07)
\d the date in "Weekday Month Date" format
(e.g., "Tue May 26")
\e an ASCII escape character (033)
\h the hostname up to the first `.'
\H the hostname
\n newline
\r carriage return
\s the name of the shell, the basename of $0
(the portion following the final slash)
\t the current time in 24-hour HH:MM:SS format
\T the current time in 12-hour HH:MM:SS format
\@ the current time in 12-hour am/pm format
\u the username of the current user
\v the version of bash (e.g., 2.00)
\V the release of bash, version + patchlevel
(e.g., 2.00.0)
\w the current working directory
\W the basename of the current working direc-
tory
\! the history number of this command
\# the command number of this command
\$ if the effective UID is 0, a #, otherwise a
$
\nnn the character corresponding to the octal
number nnn
\\ a backslash
\[ begin a sequence of non-printing characters,
which could be used to embed a terminal con-
trol sequence into the prompt
\] end a sequence of non-printing characters

You could try setting the hostname like this: hostname <newname> <rtn>

Then you can add users like this: adduser <myusername> <rtn>

Of course, you can also do it as posted above, but this always seemed easier to me than digging out a file and editing it. When adding usernames, you'll likely get a menu of things to add or do. If you don't know what you're doing at the command line with this, you can garf something up pretty quick, but re-installing hasn't ever been a big deal to me, as I do this just to fiddle with things here. After executing these two commands, you should re-boot. You'll then see your login with your new hostname.

ah u@h makes sense, lol cool so seems "easy enough" open bashrc in preferred text editor an add this line,

EDIT; i didn't have a bash rc so created a new one wih your provided code an was intending to edit the colour but even better the colour work nicely with my "terminal-colours" theme an as asked my prompts are back to something i can use (not knowing which terminal was in root at the time was most confusing,
thankyou

This is all you need:

chris@office:~$ cat .bashrc
#!/bin/sh
if [ -r /etc/profile ] ;then
. /etc/profile
fi

Copy this .bashrc in /etc/skel so that all the future users that you define will inherit it automatically.

PS1='[\u@\h:\W]\$ '

short, simple, informative.

i don't think i will be creating any more users, unless the mrs decides she wants one (no dirty comments on the please lol) but i will keep note of this.

i have just downloaded the o'reilly bash quick reference an so far have the first 18 pages printed out, so fingers crossed i may be able (eventually) to make possibly usefull scripts to be shared.

also i like you signature.

I realize that this thread is already marked "solved", but for my own education...Is it possible that the OP was referring to an xterm and all that was needed is an option to run the terminal as a "login shell"?

For example, the preferences settings in xfterm4 General --> "Run command as Login Shell". The default prompt changes from "bash 4.1" to "user@host".

What did I miss? Is there a reason NOT to have xterms run as a login shell? (<---my real question).

I know of no reason why not to use xterm as a login shell, but our solutions were aimed for all terminals, not just one in particular.
