Execute a command line and get the value...

Ok, I've been scratching and searching around for this for a while now. Basically, what I need to do is execute a function, and then return its value. The function needs to be run via a command line, i.e with the ``'s. At the moment I have;

`perl filetorun.cgi`;

However, I can't seem to be able to get the results of that page shown in a variable. I tried;

$something = `perl filetorun.cgi`;

But that didnt return anything.

Is there a function or something, like execute(), that will allow me to execute commands, and then get the result of it into a variable?

Thanks in advance

You could try,

Code:
open(RESULT, "/usr/bin/perl filetorun.cgi|"); 
@result = <RESULT>; 
close(RESULT);

The lines of your output are then stored in @result, which you can process further.

Hope that helps.
