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'.
See section 2. 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.
