How to Redirect stdout to a File Using Go's `exec.Cmd`?

Redirecting stdout to a File Using exec.Cmd in Go

Writing the stdout of an exec.Cmd to a file in Go involves capturing the output and redirecting it to a file. Here's a guide on how to accomplish this:

package main

import (
    "os"
    "os/exec"
)

func main() {

    // Open the out file for writing
    outfile, err := os.Create("./out.txt")
    if err != nil {
        panic(err)
    }
    defer outfile.Close()

    // Create the command and assign the outfile to its Stdout
    cmd := exec.Command("echo", "'WHAT THE HECK IS UP'")
    cmd.Stdout = outfile

    // Start the command and wait for it to finish
    err = cmd.Start(); if err != nil {
        panic(err)
    }
    cmd.Wait()
}

By assigning the output file to cmd.Stdout, we redirect the command's stdout output directly to the file. When the cmd.Start() method is called, the command will execute and its output will be written to the specified file.
