How to use Go language for development on Linux system?

The Go language is an open source programming language developed by Google and is designed to improve developer productivity and performance. On Linux systems, we can easily use Go language for development and make full use of its concurrency performance and other advantages. This article will introduce how to install and configure the Go language development environment on a Linux system, and give some specific code examples.

Step 1: Install Go language

1. First, open a terminal and make sure your Linux system is connected to the Internet.

2. Use the following command to download the Go language installation package:

   wget https://golang.org/dl/go1.17.5.linux-amd64.tar.gz

3. Unzip the installation package:

   tar -C /usr/local -xzf go1.17.5.linux-amd64.tar.gz

4. Set the environment variables of the Go language. Open your terminal configuration file (such as ~/.bashrc or ~/.zshrc) and add the following:

   export PATH=$PATH:/usr /local/go/bin
   export GOPATH=$HOME/go
   export PATH=$PATH:$GOPATH/bin

5. Use the source command to make the configuration effective:

   source ~/.bashrc

6. Finally, verify whether the Go language is installed successfully:

   go version

Step 2: Write the first Go program

Let us write a simple Hello World program to verify whether the installation and configuration of the Go language is successful.

1. Open your favorite text editor and create a new Go source code file hello.go and enter the following:

   package main
   
   import "fmt"
   
   func main() {
    fmt.Println("Hello, World!")
   }

2. Save the file and exit the editor.

3. Go to the directory where hello.go is saved in the terminal and run the following command to compile and run the program:

   go run hello.go

   If everything goes well, you will see the output as Hello, World!, which means you have successfully written and executed your first Go program.

Step 3: Go further

In addition to the Hello World program, the Go language also supports a rich standard library and functions. You can further learn and use these functions to Develop more complex applications. The following are some common commands for Go language programming:

• go build: Compile the Go program and generate an executable file.
• go fmt: Format Go source code.
• go get: Get remote packages (such as libraries on GitHub) and install them into the local environment.
• go test: Run the test case of the Go program.

Through learning and practice, you will gradually master the development skills of Go language and be able to write efficient and concurrent applications.

Summary:

This article introduces how to install and configure the Go language development environment on a Linux system, and demonstrates a simple Hello World program. By reading this article, you should be able to start developing in Go and gradually gain control of more advanced programming techniques. I wish you success in learning and practicing Go language!
