timeout for system commands - perl

[itai weisman]

Hi,
on perl script,
does anyone know a way to fail a system function call, if it takes too much time,
(maybe by using another function or module)
f.e.
if I'm using
system("command1");
and command1 takes too much time (or even hangs)
the whole script hangs....
any idea?

Hi,
not sure if this is what you are after:

Can you not timeout the call, once your expected execution time has elapsed?
