Open folders on Current Visual Studio Code Window from terminal

[KazukiOta]

I usually used `code .` command to open a folder using Visual Studio Code, however it open as new Window.

So, I used folder open dialog to open a folder by current Window. GUI is useful. But I sometime had felt that I don't want to leave terminal window.

The solution!!

I checked a following document. I found -r option and --add option!!

https://code.visualstudio.com/docs/editor/command-line

-r option is to open a folder by current window, --add option is to add a folder to current work space.

If I would like to add two folders to Visual Studio Code, the folder names are 'sample1' and 'sample2', and initialize as git repositories.

I just type following command:

$ mkdir sample1
$ cd sample1
$ git init
$ code -r .
$ cd ..
$ mkdir sample2
$ cd sample2
$ git init
$ code --add .

What's a useful feature!!
