NAME

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

SYNOPSIS

    use Sys::Hostname;
    $host = hostname;

DESCRIPTION

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

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