Re^2: Run and kill external programm after x seconds

in thread Run and kill external programm after x seconds

Hi,

my problem is that I run an external program X (I do not have control of this program X) and I get output from this program X. This program X may dies or don't give answer for hours.

I would like to wait for e.g. 60 seconds and if there is no new input from this program X it should be closed/killed and my perl program should go on with next steps.

kind regards, de michi

So would it not work to reverse the logic of the `m/.../` or -- at the 60 second mark -- to simply test for a void as below? `D:\_scratch>perl -e "my $foo=''; if ($foo =~//){ print 'found nothing' +;} exit();" found nothing D:\_scratch>` [download] `++$anecdote ne $data`	[reply] [d/l] [select]
