Hello!
I have had a little problem, which you might don't need to uninstall linux for. But how do I do it?

My problem was that I changed the .bashrc file, because I wanted to install java, but it didn't work out so well.
Now my X-term won't tell where I am, there is a empty screen.
Thanx!

Try moving the file to something else, like .bashrc.old. If /etc/skel/.bashrc exists, copy that to your home directory.
You can also show the contents of the file, and see if we can fix it. You really don't need to uninstall anything at all.

You dont to re-install L1nux for such a small problem..

Create a file .bashrc in your home directory and paste the following
and open a new terminal to apply the new settings .

################################################################
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi


#### FOR COLORS AND PATH DISPLAY IN THE TERMINAL#############

PS1="[\u@\h \W]\\$ " # show name & current folder - from http://overtone.org/articles/bashrc.php

# colors for ls, etc.
eval `dircolors -b /etc/DIR_COLORS`
alias d="ls --color"
alias ls="ls --color=auto"
alias ll="ls --color -l"

# Change the window title of X terminals
case $TERM in
xterm*|rxvt|Eterm|eterm|aterm|Aterm)
PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"'
;;
screen)
PROMPT_COMMAND='echo -ne "\033_${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\033\\"'
;;
esac

############################################################

go to this site and put in your .bashrc: http://www.tldp.org/LDP/abs/html/sample-bashrc.html

Now I have done that, I still don't have anything in my xterm.
Is it because I should reboot or set some references to xterm.

log out then back in

The .bashrc is like UsualTuxspect wrote:
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc

So, I don't know what to do...

please answer...i miss my x-term...

When I press ctrl-alt-f1 It says:
bash: host: unbound variable
bash: hilit: unbound variable

ok so show us our .bashrc file. what did you put in that? you can just delete it and the system default will take over as long as you weren't messing around in /etc

Now when I have deleted everything in the .bashrc -file, I get this in my x-term-window: bash-2.05 $
I might have messed with the /etc file, though.

that looks like a default prompt to me. Now just play around with your ~/.bashrc to tweak it how you want it.
