| 11 | -------- |
| 12 | [verse] |
| 13 | *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *load* [option:--force] [option:--input-path='PATH'] ['SESSION'] |

| 16 | DESCRIPTION |
| 17 | ----------- |
| 18 | The `lttng load` command loads the configurations of one or more |
| 19 | tracing sessions from files. |
| 20 | |
| 21 | The `lttng load` command is used in conjunction with the |
| 22 | man:lttng-save(1) command to save and restore the complete |
| 23 | configurations of tracing sessions. This includes the enabled channels |
| 24 | and event rules, the context added to channels, the tracing activity, |
| 25 | and more. |
| 26 | |
| 27 | Once one or more tracing session configurations are loaded, they appear |
| 28 | exactly as they were saved from the user's point of view. |
| 29 | |
| 30 | The default input path is `$LTTNG_HOME/.lttng/sessions` |
| 31 | (`$LTTNG_HOME` defaults to `$HOME`). The input path can be |
| 32 | overridden with the option:--input-path option. |
| 33 | |
| 34 | If the input path is a directory, then if 'SESSION' is specified, the |
| 35 | tracing session configuration named 'SESSION' is searched in all the |
| 36 | files of this directory and loaded if found. If 'SESSION' is not |
| 37 | specified, the option:--all option is implicit: all the tracing session |
| 38 | configurations found in all the files in this directory are loaded. |
| 39 | |
| 40 | If the input path is a file, then if 'SESSION' is specified, the tracing |
| 41 | session configuration named 'SESSION' is searched in this file and |
| 42 | loaded if found. If 'SESSION' is not specified, the option:--all option |
| 43 | is implicit: all the tracing session configurations found in this file |
| 44 | are loaded. |
| 45 | |
| 46 | By default, existing tracing sessions are not overwritten when loading; |
| 47 | the command fails. The option:--force option can be used to allow this. |
