Today my boss ask me install a tomcat in linux machine. After i ssh into that machine, i wonder what is the Linux distribution version? Red Hat? Ubuntu? Fedora? Debian?

However with a simple command, i can check what is linux distribution version

mymachine:~# cat /proc/version
Linux version 2.6.18-5-686-bigmem (Debian 2.6.18.dfsg.1-13etch3) (dannf@debian.org) 
(gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) 
#1 SMP Wed Sep 26 19:03:46 UTC 2007

I’m using Debian Linux version 2.6.18-5-686-bigmem

cat /proc/version
