Setup

This plugin requires a Rust version of at least 1.75

Install the shell plugin to get started.

Automatic

Use your project’s package manager to add the dependency:

npm

npm run tauri add shell

yarn

yarn run tauri add shell

pnpm

pnpm tauri add shell

bun

bun tauri add shell

cargo

cargo tauri add shell

Manual

1. Run the following command in the src-tauri folder to add the plugin to the project’s dependencies in Cargo.toml:

   cargo add tauri-plugin-shell

2. Modify lib.rs to initialize the plugin:

   src-tauri/src/lib.rs

   #[cfg_attr(mobile, tauri::mobile_entry_point)]
   pub fn run() {
       tauri::Builder::default()
           .plugin(tauri_plugin_shell::init())
           .run(tauri::generate_context!())
           .expect("error while running tauri application");
   }

3. Install the JavaScript Guest bindings using your preferred JavaScript package manager:

   npm

   npm install @tauri-apps/plugin-shell

   yarn

   yarn add @tauri-apps/plugin-shell

   pnpm

   pnpm add @tauri-apps/plugin-shell

   bun

   bun add @tauri-apps/plugin-shell

Usage

The shell plugin is available in both JavaScript and Rust.

JavaScript

import { Command } from '@tauri-apps/plugin-shell';
// when using `"withGlobalTauri": true`, you may use
// const { Command } = window.__TAURI_PLUGIN_SHELL__;

let result = await Command.create('exec-sh', [
  '-c',
  "echo 'Hello World!'",
]).execute();
console.log(result);

Rust

use tauri_plugin_shell::ShellExt;

let shell = app_handle.shell();
let output = tauri::async_runtime::block_on(async move {
    shell
        .command("echo")
        .args(["Hello from Rust!"])
        .output()
        .await
        .unwrap()
});
if output.status.success() {
    println!("Result: {:?}", String::from_utf8(output.stdout));
} else {
    println!("Exit with code: {}", output.status.code().unwrap());
}

Permissions

By default all potentially dangerous plugin commands and scopes are blocked and cannot be accessed. You must modify the permissions in your capabilities configuration to enable these.

See the Capabilities Overview for more information and the step by step guide to use plugin permissions.
