A program that prints out what signal was caught

sig.go

package main

import (
	"flag"
	"io"
	"log"
	"os"
	"os/signal"
	"syscall"
)

var name *string = flag.String("name", "default", "Name of process")

func main() {

	flag.Parse()

	log.SetPrefix(*name + " ")
	c := make(chan os.Signal)
	signal.Notify(c, syscall.SIGTERM, syscall.SIGINT, syscall.SIGKILL, syscall.SIGABRT, syscall.SIGPIPE)

	go io.Copy(os.Stdout, os.Stdin)

	s := <-c
	log.Println("Got signal", s)
}
