   sudo vi /etc/paths 

2. Add an extra line in the list of PATH folders as

   /Applications/Visual\ Studio\ Code.app/Contents/Resources/app/bin/ 

3. Exit from vi: Esc > :wq! > Enter Key

Restart shell. Then do echo $PATH to confirm VSCode has been added successfully.

Check code command is added by typing which code. You should see VSCode path printed on screen.
