# 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.
