Re^2: Safely passing CGI form data to a shell command

I'm curious what creating another process accomplishes? Why not just call exec() from within your own process? Could you explain? Thanks!

fork and exec is just what qx// does (w/o the shell thing). Calling exec with out forking would not let you capture and postprocess the command output... actually the command output would be sent to the remote browser!	[reply]
