9 use Sys::Hostname;
10 my $host = hostname;

13 Attempts several methods of getting the system hostname and then caches
14 the result. It tries the first available of the C library's
15 gethostname(), `$Config{aphostname}`, uname(2),
16 syscall(SYS_gethostname), `hostname`, `uname -n`, and the file
17 /com/host. If all that fails it "croak"s.

19 All NULs, returns, and newlines are removed from the result.
