Re: shell variables with Perl

You'll find the environment variables which are exported to the perl process in the %ENV hash. The name of the variable is the key, e.g. $ENV{'PATH'}.

I actually replied to this yesterady but got busy and didn't get past the preview page. All good information. The %ENV hash I totally overlooked. I remember reading it a year or so ago in Learning Perl and thinking "I won't need that for a while." I was right, but now that I needed it... For the record, a simple... `my $display = $ARGV[0]; $ENV{'DISPLAY'} = $display . ":0.0";` [download] ...worked just fine.	[reply] [d/l]
