| | 12 | -------- |
| | 13 | [verse] |
| | 14 | *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *save* [option:--force] [option:--output-path='PATH'] ['SESSION'] |

| | 17 | DESCRIPTION |
| | 18 | ----------- |
| | 19 | The `lttng save` command saves the configurations of one or more |
| | 20 | tracing sessions to files. |
| | 21 | |
| | 22 | The `lttng save` command is used in conjunction with the |
| | 23 | man:lttng-load(1) command to save and restore the complete |
| | 24 | configurations of tracing sessions. This includes the enabled channels |
| | 25 | and event rules, the context added to channels, the tracing activity, |
| | 26 | and more. `lttng save` does not save tracing data, only the tracing |
| | 27 | session parameters. |
| | 28 | |
| | 29 | If 'SESSION' is omitted, all the existing tracing session configurations |
| | 30 | are saved (equivalent to using the option:--all option). Otherwise, |
| | 31 | 'SESSION' is the name of an existing tracing session. `lttng list` |
| | 32 | outputs all the existing tracing sessions (see man:lttng-list(1)). |
| | 33 | |
| | 34 | The default output directory path is `$LTTNG_HOME/.lttng/sessions` |
| | 35 | (`$LTTNG_HOME` defaults to `$HOME`). Each tracing session configuration |
| | 36 | file is named `SESSION.lttng`, where `SESSION` is the original tracing |
| | 37 | session name. The default output directory path can be overridden with |
| | 38 | the option:--output-path option. |
| | 39 | |
| | 40 | By default, existing tracing session configuration files are not |
| | 41 | overwritten when saving; the command fails. The option:--force option |
| | 42 | can be used to allow this. |
