Thanks for your help.
I can't use system because , a nested command in my program is not
allowed, so i try the fork.
I try with waitpid($pid, XXXX) but i didn't know how to tell the waitpid
that waits for the child and don't continue
waitpid($pid,&WNOHANG) ====> continues execution without waiting for the
child, doesn't it?
waitpid($pid, !WNOHANG) ===> will wait for the child?
what is the meaning of the '&'?
Is there another flag?
