Re: System Variables

If you're after system environment variables, have a look at the ENV hash.

For example, to get the current user's home directory on a UNIX host ($HOME in shell) try :

  #!/usr/bin/perl
  use strict;
  use warnings;

  print $ENV{'HOME'}, "\n";

might be a little more informative if you do something such as: `foreach( keys %ENV ) { print "$_ = $ENV{$_} \n"; }` [download] Since what varables are available may vary from system to system. Of course just wanting to know "system variables" is sort of a vague question...	[reply] [d/l]

Or perhaps more economically, `while(my ($key, $val) = each %ENV) { print "$key = $val\n"; }` [download] since you're not sorting the keys anyway. Makeshifts last the longest.	[reply] [d/l]
