Golang check if command exists

command_exists.go

package main

import (
	"log"
	"os/exec"
)

func main() {
	path, err := exec.LookPath("ls")
	if err != nil {
		log.Fatal(err)
	}
	
	log.Println(path) // bin/ls
}

// as util
func commandExists(cmd string) bool {
	_, err := exec.LookPath(cmd)
	return err == nil
}

I haven't tried it but I guess this does not check for aliases too. Is there a way to do so?

@DrunkenPoney aliases are a shell construct. They aren't passed to sub processes. You can create executable scripts with the name of your aliases and they will be discover able like this.
