Steps to Check Go Version

Using the Command Line

The most straightforward way to check the current version of Go is via the command line.

Step 1: Open the Terminal

Open your terminal (Linux, macOS) or Command Prompt (Windows) to enter commands. Make sure you have necessary permissions to execute commands.

Step 2: Execute the Command

Type the following command and press Enter to see the current version of Go:

go version

The output will look something like this:

go version go1.19.2 linux/amd64

In this example, go1.19.2 is the version, and linux/amd64 indicates the operating system and architecture.

Verifying Installation Path

To check where Go is installed, which can verify that the path is correctly set up, use the following command:

go env GOROOT

The output will display the root directory of your Go installation.

Additional Tools

You might also want to use the go env command for additional information about your Go environment settings. For instance, to obtain detailed environment variable settings, use:

go env
