BASH Scripting - determine Ubuntu|Kubuntu|etc.

[HotShotDJ]

I do hope this is the appropriate sub-forum for this question. Does there exist a bash command (or a file that I can grep) that will return a value that will allow me to determine if the user has Ubuntu, Kubuntu, Xubuntu, etc. running? I want to use this for various case statements within a bash script. Right now, I'm using the following:

read -p "Version (Ubuntu/Kubuntu/Xubuntu/Lubuntu): "
case $REPLY inSince I'm going to be using my script for people who may not have a clue what the answer is (you know the type, they call you for help to reboot the Internet), I really want to limit the number of questions the script has to ask. Google and Forum searches have not yielded an answer. Any help with this is greatly appreciated!

Found one more in my notes:

fred@fred-LucidDT:~$ cat /etc/*release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04.1 LTS"
fred@fred-LucidDT:~$

Thank you all for your responses! Unfortunately, all the above commands return strings that contain "Ubuntu" on both my Ubuntu and Kubuntu box. I need to be able to differentiate between the different *buntu's -- that is, if the script is running on an Ubuntu box, it will return "Ubuntu"; on a Kubuntu box, it will return "Kubuntu"; etc.

if you want to run it from GUI, you can look for DE specific processes in ps output (ie gnome-session). Also you can test for ubuntu/kubuntu-desktop packages with dpkg if they are installed. Not bulletproof but can be good enough.
