-(see man:lttng-create(1) for creating a tracing session). The
-session in which a channel is disabled using `lttng disable-channel` can

-option is omitted, the current tracing session is targeted.
+A channel always belongs to a tracing session (see man:lttng-create(1)
+to create a tracing session). Without the option:--session option, the
+`disable-channel` command disables one or more channels of the current
+tracing session (see man:lttng-create(1) and man:lttng-set-session(1) to
+learn more about the current tracing session).
