Sys::Hostname(3perl) Perl Programmers Reference Guide Sys::Hostname(3perl)
NAME
Sys::Hostname - Try every conceivable way to get hostname
SYNOPSIS
use Sys::Hostname;
my $host = hostname;
DESCRIPTION
Attempts several methods of getting the system hostname and then caches
the result. It tries the first available of the C library's
gethostname(), `$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.
