gg.cmd

[Changelog] [Download]

gg.cmd is a cross-platform and cross-architecture command-line interface (CLI) that acts as an executable wrapper for various tools such as Gradle, JDK/JVM, Node.js, and Java. It requires minimal dependencies and is similar in functionality to gradlew.

Install with bash (wget):

wget ggcmd.io/gg.cmd

Install with bash (curl):

curl -L ggcmd.io > gg.cmd

Install with PowerShell:

wget ggcmd.io -OutFile gg.cmd

Install?
The concept involves placing a copy of gg.cmd in the root directory of your project.
This is similar to what you would do with gradlew or mvnw, except this method is applicable to multiple tools.
As a result, your colleagues would not have to install anything on their host machines.

Features

• Simplify the management of other executables in your project
• Automatically detect and execute the required executable version using project configuration files (such as package.json for Node.js projects)
• Support for chaining multiple executables (e.g. gradle@6:java@17)
• Cross-platform compatibility (Windows, macOS, and Linux)
• Cross-architecture compatibility (x86_64 and ARM)
• Fast and lightweight

Installs tool locally in a folder called .cache. Global install not supported. Adds every dependency into PATH before executing.

Usage

Using gg.cmd is easy. Simply place the executable in the root of your project and run it with the gg.cmd command followed by the desired executable and its required dependencies:

./gg.cmd [gg options] <executable name>@<version><+include_tags><-exclude_tags>:<dependent executable name>@<version><+include_tags><-exclude_tags> [executable arguments]

Example

sh gg.cmd npm install

Examples

Here are a few examples of how gg.cmd can make your life easier:

Execute gradle

./gg.cmd gradle build

Replace gradlew and gradle JARs by gg.cmd

You can replace gradlew with a single gg.cmd and gradle.properties and can delete these files:

• gradle/wrapper/gradle-wrapper.jar
• gradle/wrapper/gradle-wrapper.properties
• gradlew
• gradlew.bat

Execute bld

In this example, bld is used to run an app using bld for the build process:

./gg.cmd bld run

Execute JBang

./gg.cmd jbang script.java

Execute specific version of Node.js

./gg.cmd node@14

Execute specific version of Gradle and the required version of JVM/JDK

./gg.cmd gradle@6:java@17 clean build

Create a new node project

./gg.cmd npm init -y

Create a new React project

./gg.cmd npx create-react-app my-app
cp gg.cmd my-app
cd my-app
./gg.cmd npm start

Execute code hosted on GitHub

gg.cmd offers a GitHub executor. It smartly checks if the content and the available release files.

For instance, one can run GitHub's CLI tool:

> sh ./gg.cmd gh/cli/cli --verison
gh version 2.73.0 (2025-05-19)
https://github.com/cli/cli/releases/tag/v2.73.0
