How to delete a file using golang on program exit? : <p>I have made a command line application where I am zipping up folders and sharing on my local server for others to download. What I want to do is delete my copy of the zipped folder as soon as I close the server. This is my code:</p>

<pre><code>func main() {
    //flag to specify whether we will be uploading folder or a single file
    zipped := flag.Bool("z",false,"Use for zipping folders and serving them as a single file on the server.(Deletes the zipped file once the server closes.)")
    save := flag.Bool("s",false,"Use with -z for saving the zipped files locally even after the server closes.")
    flag.Parse()


    if len(flag.Args())&gt;0{

        if *zipped{
            fmt.Println("zipping...")
            flag.Args()[0]=ZipFile()

            if !(*save){
              //I expect this to remove the file when I hit ctrl+c on cmd  
              defer os.Remove(flag.Args()[0])   
                 }
        }
        http.HandleFunc("/",ShareFile)
        fmt.Printf("Sharing file on %s:8080\n",GetOutboundIP())

        log.Fatal(http.ListenAndServe(":8080",nil))
    }else{
        fmt.Println("Invalid usage. No file mentioned. Use wshare -h for help.")
    }

}
</code></pre>

<p>When I hit ctrl-c, the program exits and main function closes and as a result,shouldn't os.Remove(xyz) get executed? <a href="https://tour.golang.org/flowcontrol/12" rel="noreferrer">A tour of go</a> says, defer executes the expression when the function returns. Here, I don't feel main gets the oppurtunity to return anything at all. </p>

<p>What is a workaround to achieve what I am trying to do? I have some solutions in my head like wait for a keypress etc. but I want this program to be super simple,so is there a way to delete the file as soon as the server closes/program exits without requiring any further input from me?</p>
