// mkdir project // cd project // go mod init project // touch main.go // vim main.go // --создаем код-- package main import "syscall" // func main() { // msg := []byte("Hello, World!\n") // syscall.Write(1, msg) // } // --код завершен-- // go build -o app // ./app // go test ./... // git nint // git add . // git commit -m "init"

This example shows a basic cycle of creating and running a Go application using a system call to output text.

The code in main.go uses the syscall package to write the string "Hello, World!\n" directly to standard output (file descriptor 1):

package main

import "syscall"

func main() {
    msg := []byte("Hello, World!\n")
    syscall.Write(1, msg)
}

Next, the application is built with the command go build -o app, then run with ./app, and tested with go test ./.... After that, a git repository is initialized, changes are added, and a commit is created.

This demonstrates a minimal working example of a Go program with a system call and basic git operations.
