### 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.
