Hi everybody,

I'm puzzled about the different result of the following approaches:

# Cannot work
$ bash -c "read n; echo $n"

/* Can work */
execl ("/bin/sh", "sh", "-c", "read n; echo $n", 0);

Why they are different?
Does the option "-c" means noninteractive?
What on earth does noninteractive mean?

Try single quotes: ~$ bash -c 'read n; echo $n'
