Sys::Hostname(3)

       Sys::Hostname - Try every conceivable way to get hostname

SSYYNNOOPPSSIISS
           use Sys::Hostname;
           $host = hostname;

DDEESSCCRRIIPPTTIIOONN
       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 croaks.

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