Environment variables emanate from the user currently running the program. If you want to make a snapshot of a particular user's environment variables, save them somewhere when that user runs your code.	[reply]

I was thinking of getting the username of the owner and then logging in and doing a printenv - all from within the CGI script, but this seems exceedingly silly.	[reply]

Yes, but that's what you have to do.	[reply]

There are no "the environment variables" for any user - you can set them per process and processes' environments don't influence each other except when starting a new processes. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

Assuming a Unix environment, see RE (tilly) 3: Get default login environment for a solution.	[reply]

Unix: be the owner of the script, type "`env`". That will show you the environment. Perl has a hash called %ENV that holds the same... but in case of CGI, that should be either the environment of the webserver process or just the CGI environment from CGI.pm. Look it up in the documentation of CGI.pm. Update: ...which doesn't even mention it, sadly. You can still print in a html table `foreach my $key ( sort keys %ENV ) { print( Tr( td( $key ), td( $ENV{$key} ) ) ) }` Cheers, Sören	[reply] [d/l]

to get the real username of the running perl script you could do this: `my $owner = getpwuid($<);` [download] I apologize if I misunderstood you question.	[reply] [d/l]
