是否有可能捕捉 Ctrl + c 信号并以"defer"的方式运行一个清理函数？

Question

I want to capture the <kbd>Ctrl+C</kbd> (SIGINT) signal sent from the console and print out some partial run totals.

Is this possible in Golang?

Note: When I first posted the question I was confused about <kbd>Ctrl+C</kbd> being SIGTERM instead of SIGINT.

Answer 1

You can use the os/signal package to handle incoming signals. ^C is SIGINT, so you can use this to trap os.Interrupt.

c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
go func(){
    for sig := range c {
        // sig is a ^C, handle it
    }
}()

The manner in which you cause your program to terminate and print information is entirely up to you.
