   Okay, how about an example where one uses ' lttng list -k --xml' to get the list of kernel tracepoints and then pipes this to 'enable-event' in order to enable each event?  As a one-liner, mind you.  The idea is one would insert some sed/grep magic in the pipe to assign events to channels or filter some out.
