Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

smallnest

package main
import (
    "os"
    "exec"
)

func pipe_commands(commands ...*exec.Cmd) ([]byte, os.Error) {
    for i, command := range commands[:len(commands) - 1] {
        out, err := command.StdoutPipe()
        if err != nil {

smallnest

package main

import (
	"bytes"
	"fmt"
	"io/ioutil"
	"log"

	"golang.org/x/crypto/ssh"
	kh "golang.org/x/crypto/ssh/knownhosts"

smallnest

package main

import (
	"bufio"
	"io/ioutil"
	"os/signal"
	//"syscall"
	"fmt"
	"log"
	"os"

smallnest

package main

import (
	"bufio"
	"io/ioutil"
	"os/signal"
	//"syscall"
	"fmt"
	"log"
	"os"

smallnest

git config --global credential.modalPrompt false

smallnest

```go
func isNil(i interface{}) bool {                        
   return i == nil || reflect.ValueOf(i).IsNil()                       
}
```

better:

```go
func isNilFixed(i interface{}) bool {
