in reply to script hangs after executing program

Are you sure its this line thats causing the hang? 1st try this:

$|=1; print "got here!\n" system("$prog -f $fname ") ; print "And i also got here!\n";

My second guess is that the $prog is waiting for something, like some data to be piped to it, what does the "top" command show, is it using cpu etc?
I guess we would need a lot more info on $prog to make a better guess.

This is not a Signature...
