Is there a generic way to do this? What if the executable is only alive for a fraction of a second and I can't even fire ps to catch it? And the executable is not a script which I can add debug clauses into.
One example case is the following: I was poking around GNOME and watching syslog, for example, sliding the brightness slider and see some executable(/usr/lib/gnome-settings-daemon/gsd-backlight-helper in this case) being called to send brightness values to one monitor. I would like the command to send brightness values to all monitors, hence I am trying to find who calls it, ideally the whole chain of events.
