Sometimes we'd like our Go programs to intelligently handle Unix signals. For example, we might want a server to gracefully shutdown when it receives a SIGTERM, or a command-line tool stop processing input if it receives a SIGINT. Here's how to handle signals in Go with channels
package main import ( "fmt" "os" "os/signal" "syscall" ) func main() { sigs := make(chan os.Signal, 1) done := make(chan bool, 1) signal.Notify(sigs, syscall.SIGINT, syscall.SIGTERM) go func() { sig := <-sigs fmt.Println("") fmt.Println(sig) done <- true }() fmt.Println("awaiting signal") <-done fmt.Println("exiting") }
awaiting signal exit ^C interrupt exiting
