//usr/share/perl5/hostname.pl
# From: asherman@fmrco.com (Aaron Sherman) # # This library is no longer being maintained, and is included for backward # compatibility with Perl 4 programs which may require it. # # In particular, this should not be used as an example of modern Perl # programming techniques. # # Suggested alternative: Sys::Hostname # sub hostname { local(*P,@tmp,$hostname,$_); if (open(P,"hostname 2>&1 |") && (@tmp = <P>) && close(P)) { chop($hostname = $tmp[$#tmp]); } elsif (open(P,"uname -n 2>&1 |") && (@tmp = <P>) && close(P)) { chop($hostname = $tmp[$#tmp]); } else { die "$0: Cannot get hostname from 'hostname' or 'uname -n'\n"; } @tmp = (); close P; # Just in case we failed in an odd spot.... $hostname; } 1;
