Simple example of using channels to listen for and act on SIGINT/SIGTERM signals.

main.go

package main

import (
        "fmt"
        "os"
        "os/signal"
        "syscall"
)

// This program will run until interupted (e.g. ctrl+c).
// A channel is created to give Notify a place to send our designated signals
// A second channel waits for a signal to be "done"
// On SIGINT/SIGTERM we send true to done and exit
func main() {
        signals := make(chan os.Signal, 1)

        signal.Notify(signals, syscall.SIGINT, syscall.SIGTERM)

        done := make(chan bool, 1)

        go func() {
                recSig := <-signals
                fmt.Println()
                fmt.Println(recSig)
                done <- true
        }()

        fmt.Println("Don't worry I'll wait...")
        <-done
        fmt.Println("Ok, done waiting...")
}
