To set a particular host name, enter the following command as root with the relevant option:

~]# hostnamectl set-hostname name [option...]

Where option is one or more of: --pretty, --static, and --transient.

If the --static or --transient options are used together with the --pretty option, the static and transient host names will be simplified forms of the pretty host name. Spaces will be replaced with “-” and special characters will be removed. If the --pretty option is not given, no simplification takes place.

When setting a pretty host name, remember to use the appropriate quotation marks if the host name contains spaces or a single quotation mark. For example:

~]$ hostnamectl set-hostname "Stephen's notebook" --pretty
