[SOLVED] Linux Prompt user/Greeting

azzi · 11-09-2012, 12:10 AM

Hi,
I can't seem to get this right.
Lets say I have root privileges and I wanted:
a ) edit the user prompt to show "linux1234$" whenever they log-in.
also
b ) Show a message for users upon logging in.

I know a) has something to do with editing PS1. but how to only apply the change for users?

b ) I know there are or is a file that will enable me to accomplish this, but which or what are they?

I'm pretty new to this, so any help or guidance will be appreciated.

Thanks in advance...

Here's where I'd start:
For individual users, ~/.bashrc.
For everyone, /etc/bashrc (or /etc/bash.bashrc, depending on distro)

(1) In order to set user prompt, add following 2 lines at the end of /home/<user>/.bashrc file as follow (for bash):

Code:

prompt="linux1234$"
export prompt

For c shell or ksh, do change the syntax to set prompt="linux1234$" and append the same in .cshrc or .kshrc file. Also if 1234 is command number, then use, prompt="linux\!$"

(2) To set a greeting message, just add your message in /etc/issue or /etc/motd file.

There are actually 2 questions:
How to set prompt and how to shoe some message to the user.
There is simple script /etc/profile.d/myenv.sh:
PS1=`hostname|cut -d. -f1`:'['${USER}']''$PWD: '
HISTSIZE=10000
export PS1 HISTSIZE
if [ "$TERM" != "dumb" ]; then
if [ -f /etc/motd -a -s /etc/motd ]; then
cat /etc/motd
fi
fi

Then you can update /etc/motd if you want it to be shown at login time.
