The simplest Unix tools are real and fake. There are only a few programs that do nothing. They can only return 0 and 1 respectively to the operating system and exit. Examples in C It might look like this:
// true-does nothing successfully
int main(void) {
return 0;
}
After searching, I can’t find a way to implement this kind of functionality in Haskell. Is there anything that can be done in the IO monad?
Use one of the functions defined in System.Exit.
