uname-graalvm-demo

A simple demo of uname system call from Java using GraalVM. It fetches kernel information similar to the uname command found in Unix-likes.

Building

You'll need JDK 11 or higher installed. Use the following command to build:

./gradlew nativeImage

After compilation is done, run it using:

./build/graal/uname-graal

Output

You can see most of the uname -a information in the output, although it's not in a single line:

$ ./build/graal/uname-graal
