hostname

pi@raspberrypi:~ $ hostname -h
Usage: hostname [-b] {hostname|-F file}         set host name (from file)
       hostname [-a|-A|-d|-f|-i|-I|-s|-y]       display formatted name
       hostname                                 display host name

       {yp,nis,}domainname {nisdomain|-F file}  set NIS domain name (from file)
       {yp,nis,}domainname                      display NIS domain name

       dnsdomainname                            display dns domain name

       hostname -V|--version|-h|--help          print info and exit

Program name:
       {yp,nis,}domainname=hostname -y
       dnsdomainname=hostname -d

Program options:
    -a, --alias            alias names
    -A, --all-fqdns        all long host names (FQDNs)
    -b, --boot             set default hostname if none available
    -d, --domain           DNS domain name
    -f, --fqdn, --long     long host name (FQDN)
    -F, --file             read host name or NIS domain name from given file
    -i, --ip-address       addresses for the host name
    -I, --all-ip-addresses all addresses for the host
    -s, --short            short host name
    -y, --yp, --nis        NIS/YP domain name

Description:
   This command can get or set the host name or the NIS domain name. You can
   also get the DNS domain or the FQDN (fully qualified domain name).
   Unless you are using bind or NIS for host lookups you can change the
   FQDN (Fully Qualified Domain Name) and the DNS domain name (which is
   part of the FQDN) in the /etc/hosts file.

HOSTNAME(1)               General Commands Manual               HOSTNAME(1)

NAME
     hostname – set or print name of current host system

SYNOPSIS
     hostname [-f] [-s | -d] [name-of-host]

DESCRIPTION
     The hostname utility prints the name of the current host.
     The super-user can set the hostname by supplying an argument.
     To keep the hostname between reboots, run ‘scutil --set HostName name-of-host’.

     Options:

     -f    Include domain information in the printed name.  This is the default behavior.

     -s    Trim off any domain information from the printed name.

     -d    Only print domain information.

EXAMPLES
     Set the host name of the machine and check the result:

           $ hostname beastie.localdomain.org
           $ hostname
           beastie.localdomain.org

     Do not show domain information:

           $ hostname -s
           beastie

     Show only domain information:

           $ hostname -d
           localdomain.org
