如何暂停程序？

Question

I want to realize the pause function like windows shell command pause. For example,

$ go run script.go 
Any key to continue...     //Then any key to continue

On windows, we can use the system command by golang function exec.Command(). But how about on Linux? I want to use the command read -n1 -p "Any key to continue" as a compromised one, but it doesn't work in the function exec.Command("read", "-n", "1"). I tested a lot but failed to know why.

Besides, do anyone know how to achieve the pause function just by golang language itself without using the external command?
