coreutils: hostid invocation

 
 21.6 ‘hostid’: Print numeric host identifier
 ============================================
 
 ‘hostid’ prints the numeric identifier of the current host in
 hexadecimal.  This command accepts no arguments.  The only options are
 ‘--help’ and ‘--version’.  ⇒Common options.
 
    For example, here’s what it prints on one system I use:
 
      $ hostid
      1bac013d
 
    On that system, the 32-bit quantity happens to be closely related to
 the system’s Internet address, but that isn’t always the case.
 
    ‘hostid’ is installed only on systems that have the ‘gethostid’
 function, so portable scripts should not rely on its existence.
 
    An exit status of zero indicates success, and a nonzero value
 indicates failure.
