 The `lttng load` command loads the configurations of one or more

 The `lttng load` command loads the configurations of one or more
 tracing sessions from files.
 

-The `lttng load` command is used in conjunction with the

-configurations of tracing sessions. This includes the enabled channels

+See man:lttng-concepts(7) to learn more about tracing sessions.

+LTTng searches the following directories, non-recursively, in this order

-The input path can be overridden with the option:--input-path option.
-When this option is specified, the default directories are :not:
-searched for configuration files. When it's not specified, _both_
-default directories are searched for configuration files.
-
-If the input path is a *directory*, then:
+Override the input path with the option:--input-path='PATH' option. With
+this option, LTTng does :not: search the default directories above.
+'PATH' can be the path of one of:

 
 

-* If 'SESSION' is specified, the tracing session configuration named
-  'SESSION' is searched for in all the files of this directory and
-  loaded if found.
-* If 'SESSION' is not specified, the option:--all option is implicit:
-  all the tracing session configurations found in all the files in this
-  directory are loaded.
+A directory::
+    With the 'SESSION' argument:::
+        LTTng searches for the tracing session configuration named
+        'SESSION' in all the files of the directory 'PATH' and loads it
+        if found.

 
 

-If the input path is a *file*, then:
+    Without the 'SESSION' argument:::
+        The option:--all option is implicit: LTTng loads all the tracing
+        session configurations found in all the files in the directory
+        'PATH'.

 
 

-* If 'SESSION' is specified, the tracing session configuration named
-  'SESSION' is searched for in this file and loaded if found.

-  all the tracing session configurations found in this file are loaded.
+A file::

+        LTTng searches for the tracing session configuration named

-Aspects of the loaded configurations can be overridden at load time.

+        The option:--all option is implicit: LTTng loads all the tracing
+        session configurations found in the file 'PATH'.

 
 

-option:--override-url::
-    Provides the equivalent of the option:--set-url option
-    of the (1)lttng-create command. The validity of the url override is
-    dependant on the type of session(s) to be loaded. Refer to (1)lttng-create for
-    the accepted URL format.
+Override the output URL of the loaded tracing session configurations
+with the option:--override-url option.

 
 

-option:--override-name::
-    Set the session name to NAME. This option is invalid in combination with
-    the --all option.
+With the 'SESSION' argument, override the name of the loaded tracing
+session configuration with the option:--override-name option.

 
 

-By default, existing tracing sessions are not overwritten when loading:
-the command fails. The option:--force option can be used to allow this.
+By default, the `load` command does :not: overwrite existing tracing
+sessions: the command fails. Allow the `load` command to overwrite
