Using system() like an http "get"

I have a number of pages on a website that run perl scripts to create
different content. They are all basically accessed with an HREF such
as:

scriptname.pl?param1=1¶m2=2 etc

The question I have is, an I use the same syntax in a system call from
another perl program, ie:

system("scriptname.pl?param1=1¶m2=2");

No. system() executes a program specified on the command line.
Unless "scriptname.pl?param1=1¶m2=2" is a valid command you could
type at your console window, you can't use system() for it.

You want LWP::Simple, and it's "get" method:

use LWP::Simple;
my $content = get("http://www.example.com/scriptname.pl?
param1=1¶m2=2");

Thats what I realized after I posted the message. But thinking about
it, since the script I want to call is on the same server and in the
same directory I should be able to modify the ENV{'QUERY_STRING'} to
contain the new data then if I use system on the other script it
"should" work the same as if I called it from an HREF, or am I really
missing something here?

... but not like that. On my web server (Sun Solaris), this works at the
command line:

env -i QUERY_STRING="param1=1¶m2=2" /path/scriptname.pl

and presumably would work in a system() call as well, although I have not
tested it. Similar behavior would be expected under other flavors of Unix.

If your scripts use CGI, you might be able to get away with this:

system("scriptname.pl param1=1 param2=2");

See http://perldoc.perl.org/CGI.html#DEBUGGING
