How well does the Linux system support the Go language?

The Linux system has very good support for the Go language. The Go language itself is a programming language developed by Google, and most of Google's infrastructure such as servers and cloud computing run on Linux systems. , so the Go language is widely used on Linux systems. The following will introduce in detail the extent to which the Linux system supports the Go language, and demonstrate its application on the Linux system through code examples.

1. Building the development environment of Go language on Linux system

It is very simple to build the development environment of Go language on Linux system. You only need to download the corresponding Linux version of Go language. Install the package, unzip it and add it to the environment variables. The following are the steps to install the Go language on a Linux system:

(1) Download the Go language installation package:

wget https://golang.org/dl/go1.17.2.linux- amd64.tar.gz

(2) Unzip the installation package:

tar -C /usr/local -xzf go1.17.2.linux-amd64.tar.gz

(3) Set environment variables:

Add the following configuration in ~/.bashrc or ~/.zshrc:

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

Execute the following command to take effect:

source ~/.bashrc

2. Use Go language to write on the Linux system and Running code

Writing and running Go language code on a Linux system is also very simple. The following is a simple Go language program that demonstrates how to write and run code on a Linux system:

package main

import "fmt"

func main() {
    fmt.Println("Hello, Linux with Go!")
}

Save the above code as hello.go, and then execute the following command in the terminal to compile and run the program:

go run hello.go

The running result will output Hello, Linux with Go!, indicating that the program runs successfully on the Linux system.

3. Using Go language for system programming on Linux systems

Since Go language inherently supports concurrency and parallel programming, it is very convenient to use Go language for system programming on Linux systems. convenient. Go language provides standard libraries such as os and syscall, which can easily call the system calls provided by the Linux system for system programming. The following is a simple example that demonstrates how to create a file and write the content using Go language on a Linux system:

package main

import (
    "os"
)

func main() {
    file, err := os.Create("test.txt")
    if err != nil {
        panic(err)
    }
    defer file.Close()

    data := []byte("Hello, Go system programming on Linux!")
    _, err = file.Write(data)
    if err != nil {
        panic(err)
    }
}

Save the above code as sysprog.go, and then execute the following command in the terminal to compile and run the program:

go run sysprog.go

The program will create a file named test.txt in the current directory and write the content Hello, Go system programming on Linux!.

Summarize:

The Linux system has very good support for the Go language. You can easily build a Go language development environment on Linux, and perform system programming through the powerful standard library of the Go language to realize various functions. At the same time, the Go language inherently supports concurrent programming and can efficiently utilize Linux system resources. Therefore, using the Go language to develop applications on the Linux system is a very good choice.
