 DESCRIPTION

-The `lttng save` command saves the configurations of one or more
-tracing sessions to files.
+The `lttng save` command saves to files the configurations of:

 
 

-The `lttng save` command is used in conjunction with the
-man:lttng-load(1) command to save and restore the complete
-configurations of tracing sessions. This includes the enabled channels
-and recording event rules, the context added to channels, the tracing
-activity, and more. `lttng save` does not save tracing data, only the
-tracing session parameters.
+With the 'SESSION' argument::
+       The tracing session named 'SESSION'.

 
 

-If 'SESSION' is omitted, all the existing tracing session configurations
-are saved (equivalent to using the option:--all option). Otherwise,
-'SESSION' is the name of an existing tracing session. `lttng list`
-outputs all the existing tracing sessions (see man:lttng-list(1)).
+Without the 'SESSION' argument::
+    *All* the tracing 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.
+
+See man:lttng-concepts(7) to learn more about tracing sessions.
+
+Use the `save` command in conjunction with the man:lttng-load(1) command
+to save and restore the complete configurations of tracing sessions.
+
+The `save` command does :not: save tracing data, only the tracing
+session parameters, including the channel and recording event rule
+configurations.

 
 The default output directory path is `$LTTNG_HOME/.lttng/sessions`
 
 The default output directory path is `$LTTNG_HOME/.lttng/sessions`

-(`$LTTNG_HOME` defaults to `$HOME`). Each tracing session configuration
-file is named `SESSION.lttng`, where `SESSION` is the original tracing
-session name. The default output directory path can be overridden with
-the option:--output-path option.
+(`$LTTNG_HOME` defaults to `$HOME`). Override the default output
+directory path with the option:--output-path option. Each tracing
+session configuration file is named __SNAME__++.lttng++,
+where{nbsp}__SNAME__ is the original tracing session name.

 
 

-By default, existing tracing session configuration files are not
-overwritten when saving; the command fails. The option:--force option
-can be used to allow this.
+By default, the `save` command does :not: overwrite existing tracing
+session configuration files: the command fails. Allow the `save` command
+to overwrite existing tracing session configuration files with the
