Does closing the handler also kills the command?	[reply]

It would send a SIGPIPE which may or may not stop the command. This stuff is rather system specific and I'm not sure if what's the default on Windows. Just try. Otherwise if you really need a Ctrl-C to be sent: this form of `open()` returns the child's PID so you can use `kill 2, $pid` to send the signal.	[reply] [d/l]

I think windows doesn't quite respect 'kill'. This (run on Windows 7 Professional, ActivePerl v5.12.4) `perl -e "$pid = open PIPE, '-\|', 'echo one two';$/=' '; while (<PIPE>) +{ print; kill 2, $pid}"` [download] outputs one two But this `perl -e "$pid = open PIPE, '-\|', 'echo one two';$/=' '; while (<PIPE>) +{ print; close PIPE}"` [download] outputs one	[reply] [d/l] [select]
