[root@stephan ~]# echo stephan2 > /etc/hostname # this is the file that your system reads on boot, to determine the hostname
[root@stephan ~]# sed -i s/stephan/stephan2/g /etc/hosts # many networking headaches will ensue if this isn't updated
[root@stephan ~]# hostname -F /etc/hostname # reread the hostname file to update the systems hostname.
Your prompt will continue to display the old hostname until you log out of it and back in, or execute a new shell session.

'sed' is the stream text editor. It's a command that changes text in place, either from a stream of text you 'pipe' into it, or occurrences of that text in a file. en.wikipedia.org/wiki/Sed
