I don't know how to search for this and that is why I asked for it (all my searches did not reveal any relevant information).
I have a Fedora 18 server that looks like this:
[root@dhcp-192-168-5-100 ~]#
I want to change that to:
[root@server1 ~]#
Currently, this machine is set to get IP through DHCP, but that is not the IP address of the machine and that is why I need to change the CLI to something more relevant.
Thank you

To change the hostname of a device in Linux, we recommend using CLI tools. These methods are universal and will work on almost any Linux distro. Furthermore, there is also no need to install any additional packages. First, check the hostname of the current system as follows.
How to Set the Hostname. Let's just edit the /etc/hostname file to change the hostname. To do that, we should be root or the sudo user. Then, the modification is immediately reflected by the hostname command and isn't lost after rebooting.
/etc/sysconfig/network and change/add HOSTNAME variable like so HOSTNAME=server1.domain.com After restart it should have server1.server1 and server1.domain.com to 127.0.0.1 line, so it will look like: 127.0.0.1 localhost.localdomain localhost server1 server1.domain.com
More about network file you can read here: https://docs.fedoraproject.org/en-US/Fedora/15/html/Deployment_Guide/ch-The_sysconfig_Directory.html#s2-sysconfig-network

you can type "hostname HOSTNAME" where HOSTNAME is the new name you want. The next time you log in / connect via ssh, that's what you'll see.
