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'. *Note 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.
An exit status of zero indicates success, and a nonzero value
indicates failure.
