I'm using RH8, I was wondering how to change the host/prompt in the console.

For example, mine looks like: [CauSTiC@The-Lab CauSTiC]$

That's one too many caustic's for me. I'd rather just have [CauSTiC@The-Lab]$ if possible.

Is it?

Thanks in advance!

Peace

Of course it's possible, read man bash, about PS1 and PS2 variables, you can even change the colour of your prompt, also search the web for bash prompt customization or such, and then i know they have a section about this on muhri.net (tips and tricks section) and somewhere on linuxbrit.co.uk too.
Meanwhile here's mine:
#!/bin/bash
# Start - bash prompt colours
# Folloing lines define coloured bash prompts
# Green () for normal users Red () for root
COLOR1="\[\033[0;36m\]"
COLOR2="\[\033[0;32m\]"
COLOR3="\[\033[0;36m\]"
COLOR4="\[\033[1;37m\]"
if

[ "$UID" = "0" ];
then
# I am root
COLOR2="\[\033[1;31m\]"
fi
PS1="$COLOR2--($COLOR3\d, \t$COLOR2)--$COLOR2($COLOR3\u@\H$COLOR2:$COLOR1\w$COLOR2)$COLOR1\\$ $COLOR4"
# End - bash prompt colours

NSKL:
Can you advise me how to make my PS1 red?
mine is: PS1="\u@ \w# "
???

I just stuck the shell script i posted above into /etc/profile.d and called it shell.sh , and bash reads it every time it starts.
Now to make your prompt red you'll probably want to edit the script above, thats the easiest way i beleive.
Also check out http://www.linuxbrit.co.uk/bashprompt/ and just edit some of his scripts to fit your needs. Also read on ASCII color codes (i beleive its called like that) to learn the codes for colours, they are used in my script above, and the scripts from the link i gave you.
Also if i recall well theres a nice explanation about this in the bash HOW-To or the bash prompt HOW-TO...
Hope that helps

Reading Bash-prompt howto I have discovered many interesting things

One more question, I have puted such command:
PS1="\[\033[0;031m\]\u@ \[\033[0;31m\]\w# "
So everything I type becomes red, and want red to be only the prompt???

To make only the prompt red the command line should go like this
PS1="\[\033[0;031m\]\u@ \[\033[0;31m\]\w# \033[0;0m\]"
