If you want to log it for SIGHUP in /var/run/process.pid would the parent work as well? > Use Proc::ProcessTable to get the pid of your program name. > Here is an example: ---8<snip script Not sure I understand what I'm supposed to be seeing. None of this output resembles a pid. I shortened the count up to 10 and watched it output to STDOUT and to a separate tty... output STDOUT 1 2 3 [...] other TTY 1a 2a 3a [...]' NOt sure I get what this has to do with two pids involved. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
