You could try to start the command and then execute 
	pidof command name
which should return the PID(s) of running commands, which you could
kill/hangup with yet another command.

Not totally on-topic, but after a discussion with a friend yesterday I
am curious if the functionality of ggee/shell can't be achieved with
pd-send and pd-receive as well?
