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

+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:

-default directories are searched for configuration files.
+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:
+
+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 *directory*, 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 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 file::

+Override the output URL of the loaded tracing session configurations
+with the option:--override-url option.

 
 

-By default, existing tracing sessions are not overwritten when loading:
-the command fails. The option:--force option can be used to allow this.
+With the 'SESSION' argument, override the name of the loaded tracing
+session configuration with the option:--override-name option.

 
 

+By default, the `load` command does :not: overwrite existing tracing
+sessions: the command fails. Allow the `load` command to overwrite
+existing tracing sessions with the option:--force option.
