# Syncthing Deck Setup
|
||||
|
||||
This script will download a Syncthing build and install it in the user's home
|
||||
directory. This allows a user to run Syncthing using a SystemD user service, and
|
||||
keep all necessary files within their home directory. In scenarios where the
|
||||
traditional directory for installed packages may be overwritten (ie., the Steam
|
||||
Deck's filesystem), this allows Syncthing to persist through updates, and still
|
||||
run automatically in the background when the Deck is started. There is no GUI
|
||||
provided for Syncthing when installed this way. Instead, use the web-UI
|
||||
available at `localhost:8384`.
|
||||
|
||||
## Requirements
|
||||
|
||||
- `bash`
|
||||
- `curl`
|
||||
- `tar`
|
||||
|
||||
## Usage
|
||||
|
||||
Run the script. Optionally include a version, a platform, and an architecture.
|
||||
Acceptable values can be found on the [Syncthing
|
||||
Releases](https://github.com/syncthing/syncthing/releases) page.
|
||||
|
||||
```
|
||||
Usage: syncthing-deck-setup [<options>]
|
||||
|
||||
-V, --version Specify a Syncthing Version. Default is latest.
|
||||
-P, --platform Specify an OS/Platform. Default is linux.
|
||||
-A, --arch Specify an architecture. Default is amd64.
|
||||
-U, --uninstall Remove files setup with this script.
|
||||
-v Show version
|
||||
-h Show this usage
|
||||
```
