How can I programmatically clear the terminal window, equivalent to pressing `Ctrl+l`?

Thanks!  
I’ll add a semicolon `;` to avoid the printed output. (there’s still an extraneous empty line left on my terminal, but that’s fine).

`write(stdin.buffer, 0x0C)` works on both linux and Windows.

For completeness, it also works on macOS:

This is not doing what I expected it to do though

```julia
julia> for i in 1:10
           write(stdin.buffer, 0x0C)
           println("test", i)
       end

```

What _are_ you expecting that to do?

I’d expected that to go (very quickly, prob. not visible) from `test1` to `test10` and `test10` still be visible at the end.  
Instead I end with a cleared terminal.

You should probably use something like

```julia
julia> for i in 1:10
           print("\e[0;0H\e[2J")
           println("test", i)
           sleep(0.1)
       end

```

for that.
