7.2.62 Sys::Hostname - Try Every Conceivable Way to Get Hostname

use Sys::Hostname;
$host = hostname();

Attempts several methods of getting the system hostname and then caches the result. It tries syscall(SYS_gethostname), `hostname`, `uname -n`, and the file /com/host. If all that fails, it croak()s.

All nulls, returns, and newlines are removed from the result.
