Hi All,

I have a perl program that uses the following to get information from another process:

$tail_id = open(GET_INFO, "tail -1lf info_file 2>/dev/null|") || die "
+Can't check info_file: $!\n";
$mw->fileevent(\*GET_INFO, 'readable' => [\&input_from_tail, $mw, info
+_file]);

[download]

When the perl program finishes the tail command is left running away and has to be killed manually.

Is there a way to end the tail command when the perl program finishes?

I've tried using a $SIG{'QUIT'} and $SIG{'TERM'} to get them to close the pipe to the tail command but they don't appear to work. When the user exits the program nothing happens.

Any ideas?
