# karma-scripts-launcher > Launcher for a shell script. This plugin allows you to use a shell script as a browser launcher. The script has to accept a single argument - the url that the browser should open. ## Installation **This plugin ships with Karma by default, so you don't need to install it, it should just work ;-)** The easiest way is to keep `karma-scripts-launcher` as a devDependency in your `package.json`. ```json { "devDependencies": { "karma": "~0.10", "karma-scripts-launcher": "~0.1" } } ``` You can simple do it by: ```bash npm install karma-scripts-launcher --save-dev ``` ## Configuration ```js // karma.conf.js module.exports = function(config) { config.set({ browsers: ['/usr/local/bin/my-custom.sh'], }); }; ``` You can pass list of browsers as a CLI argument too: ```bash karma start --browsers /some/custom/script.sh ``` ---- For more information on Karma see the [homepage].
