 SYNOPSIS

 DESCRIPTION
 -----------
-The `lttng clear` command clears one or more tracing sessions, that is,
-it deletes the contents of their tracing buffers and all their local and
-streamed trace data.
+The `lttng clear` command clears one or more recording sessions, that
+is, it deletes the contents of their recording buffers and of all their
+local and streamed trace data.
 
-If no options are specified, the current tracing session is cleared
-(see man:lttng-create(1) for more information about the current
-tracing session).
+See man:lttng-concepts(7) to learn more about recording sessions.
 
-If 'SESSION' is specified, the existing tracing session named 'SESSION'
-is cleared.
+The `clear` command clears:
 
-With the option:--all option, *all* the tracing sessions, as listed in
-the output of `lttng list` (see man:lttng-list(1)), are cleared.
+Without any option::
+    The current recording session.
++
+See man:lttng-concepts(7) to learn more about the current recording
+session.
 
-If a tracing session is configured in snapshot mode (see the
-man:lttng-create(1) command's nloption:--snapshot option), only the
-tracing buffers are cleared.
+With the 'SESSION' argument::
+    The recording session named 'SESSION'.
 
-For a given tracing session, if at least one rotation occurred (see
-man:lttng-rotate(1)), only its tracing buffers and its current trace
-chunk are cleared; its archived trace chunks are :not: cleared.
+With the option:--all option::
+    *All* the recording sessions of the connected session daemon for
+    your Unix user, or for all users if your Unix user is `root`, as
+    listed in the output of `lttng list` (see man:lttng-list(1)).
++
+See the ``Session daemon connection'' section of man:lttng(1) to learn
+how a user application connects to a session daemon.
+
+If a recording session is configured in snapshot mode (see the
+nloption:--snapshot option of the man:lttng-create(1) command), the
+`clear` command only clears the recording buffers.
+
+For a given recording session, if at least one rotation occurred (see
+man:lttng-concepts(7)), the `clear` command only clears its recording
+buffers and its current trace chunk, :not: its archived trace chunks.
 
 NOTE: The nloption:--disallow-clear option and the
 `LTTNG_RELAYD_DISALLOW_CLEAR` environment variable of
 man:lttng-relayd(8) can disable remote clearing operations. If LTTng
-sends tracing data over the network for 'SESSION' (or for any tracing
-session with the option:--all option) to a relay daemon configured as
-such, `lttng clear` fails.
+sends recording data over the network for the selected recording
+session(s) to an LTTng relay daemon configured as such, the `clear`
+command fails.
