hostid
hostid prints the host's numeric identifier, in hexadecimal.
hostid
$ hostid
007f0100
The host id is a number associated with the system. It takes no options and prints one value.
Where hostname gives the system's name — meant to be read by people — hostid gives a numeric value, used by software that wants a machine identifier in a fixed numeric form.
