Sys::Hostname(3) Perl Programmers Reference Guide Sys::Hostname(3) NAME Sys::Hostname - Try every conceivable way to get hostname SYNOPSIS use Sys::Hostname; $host(1,5) = hostname; DESCRIPTION Attempts several methods of getting the system hostname and then caches the result. It tries the first available of the C library's gethost- name(), `$Config{aphostname}`, uname(1,2)(2), "syscall(SYS_gethostname)", `hostname`, `uname(1,2) -n`, and the file(1,n) /com/host(1,5). If all that fails it "croak"s. All NULs, returns, and newlines are removed from the result.
