[Help-bash] Use pid of cmd run in sub shell in parent shell?

[Patrick Schleizer]

Hi!

The following works well. Except that I have no idea how to get the pid
of long_running_cmd_here outside the subshell. Any idea?

=====

while read line; do
   log "...: $line"
done < <(
   {
      long_running_cmd_here
   }
) &

echo "Need pid of long_running_cmd_here here."

=====

I need the pid of long_running_cmd_here for job control, so I can send
signals to long_running_cmd_here.

Cheers,
Patrick
