You can access environment variables though the %ENV hash. I've listed a
couple standard ways to do so below. If you are creating the variable just
export it and it will be picked up by %ENV. At least it works that way
for bash.
------------------------------------
#!/usr/bin/perl
use warnings;
use strict;
# print logname
my $log_name = ($ENV{'LOGNAME'});
print "$log_name\n";
# print all ENV variables
foreach (sort keys %ENV) {
print "$_ = $ENV{$_}\n";
}
-----------------------------------
