The mechanics of anonymous pipes

Anonymous pipes are the most basic form of pipes. They are used for communication between parent and child processes. Let’s explore how we can replicate the simple script beforementioned:

package main
import (
    "fmt"
    "os"
    "os/exec"
)
func main() {
    echoCmd := exec.Command("echo", "Hello, world!")
    grepCmd := exec.Command("grep","Hello")
    pipe, err := echoCmd.StdoutPipe()
    if err != nil {
        fmt.Fprintf(os.Stderr, "Error creating StdoutPipe for echoCmd: %v\n", err)
        return
    }
    if err := grepCmd.Start(); err != nil {
        fmt...
