[Zeno-Code]

func main() {
    host := flag.String("host", "abc.com", "domain")
    flag.Parse()
    fmt.Printf("%#v", *host)
}
`

main -host abcde.com
"abcde.com"

rizla main.go -host abcde.com
"abc.com"

what should I do？

Update with go get -u github.com/kataras/rizla and you should be able to run: rizla main.go -host abcde.com as you requested
