I have 1 executable which runs several process in sequence. Since these processes takes a lot of time, I want the executable to work as a daemon and print to me it's current status when I'm sending a signal to it.

I've made all this work, but every time I send a signal to it to get the current status it kills the current process to give me the information. So do I need to set some parameters or something to make sure children can work unaffected by parents signal status?
This is my code in short:

$SIG{USR1} = \&status; sub status () { $SIG{USR1} = \&status; print "\n Status is: $status"; } foreach $path (@paths) { my $pid = open3(*CMD_IN, *CMD_OUT, *CMD_ERR, $path); $status = $path; waitpid($pid, 0); }

Any suggestions ?
