# Command line interface (CLI)
|
|
|
|
LosslessCut has basic support for automation through the CLI. See also [HTTP API](./api.md).
|
|
|
|
```bash
|
|
LosslessCut [options] [files]
|
|
```
|
|
|
|
Note that these examples assume that you have set up the LosslessCut executable to be available in your `PATH` (command line environment). Alternatively you can run it like this:
|
|
|
|
```bash
|
|
# First navigate to the folder containing the LosslessCut app
|
|
cd /path/to/directory/containing/app
|
|
# Then run it
|
|
# On Linux:
|
|
./LosslessCut arguments
|
|
# On Windows:
|
|
./LosslessCut.exe arguments
|
|
# On MacOS:
|
|
./LosslessCut.app/Contents/MacOS/LosslessCut arguments
|
|
```
|
|
|
|
## Open one or more files:
|
|
```bash
|
|
LosslessCut file1.mp4 file2.mkv
|
|
```
|
|
|
|
## Override settings (experimental)
|
|
See [available settings](https://github.com/mifi/lossless-cut/blob/master/public/configStore.js). Note that this is subject to change in newer versions. ⚠️ If you specify incorrect values it could corrupt your configuration file. You may use JSON or JSON5. Example:
|
|
```bash
|
|
LosslessCut --settings-json '{captureFormat:"jpeg", "keyframeCut":true}'
|
|
```
|
|
|
|
## Other options
|
|
|
|
- `--locales-path` Customise path to locales (useful for [translators](./translation.md)).
|
|
- `--disable-networking` Turn off all network requests.
|
|
- `--http-api` Start the [HTTP server with an API](./api.md) to control LosslessCut, optionally specifying a port (default `8080`).
|
|
- `--keyboard-action` Run a keyboard action (see below.)
|
|
|
|
## Controlling a running instance (experimental)
|
|
|
|
If you have the "Allow multiple instances" setting enabled, you can control a running instance of LosslessCut from the outside, using for example a command line. You do this by issuing messages to it through the `LosslessCut` command. Currently only keyboard actions are supported, and you can open files. *Note that this is considered experimental and the API may change at any time.*
|
|
|
|
### Keyboard actions, `--keyboard-action`
|
|
|
|
Simulate a keyboard press action in an already running instance of LosslessCut. Note that the command will return immediately, so if you want to run multiple actions in a sequence, you have to `sleep` for a few seconds between the commands. Alternatively if you want to wait until an action has finished processing, you can use the [HTTP API](./api.md) instead. Note that the HTTP API does not support opening files, and it is currently not possible to wait for a file to have finished opening.
|
|
|
|
### Available keyboard actions
|
|
|
|
A list of the available action names can be found in the "Keyboard shortcuts" dialog in the app. Note that you don't have to bind them to any key before using them.
|
|
|
|
Example:
|
|
|
|
```bash
|
|
# Open a file in an already running instance
|
|
LosslessCut file.mp4
|
|
sleep 3 # hopefully the file has loaded by now
|
|
# Export the currently opened file
|
|
LosslessCut --keyboard-action export
|
|
```
|
|
|
|
### Open files in running instance
|
|
|
|
```bash
|
|
LosslessCut file1.mp4 file2.mkv
|
|
```
