Hi! :)

I am trying to execute an external command within class method using system() call. What I found is that no error is generated, everything goes fine but no results from that execution. In my test environment, when I tried to execute the exact system call but within main CGI script, everything goes fine.

I've searched a lot about that problem but can't think of what's causing it. Indeed, after a lot of tryings (even executing main:: stuff) I found a solution that seems strange to me - I added "&" (background execution) when executing the command within the class method package definition and everything went fine !?!

So my question is what's going on? It is supposed that system forks, executes the external command, waits for its completion and returns the status of that completion. What's the difference when executing system() within object and main script environment and why putting the external program in background works?

Thanks for your future answers, monks! :)

Best Regards,
