$ mas lucky twitter
==> Downloading Twitter
==> Installed Twitter
> `mas` is only able to install/update applications that are listed in the Mac App Store itself. Use [`softwareupdate(8)`](https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man8/softwareupdate.8.html) utility for downloading system updates (like iTunes, Xcode Command Line Tools, etc)
To install all pending updates run `mas upgrade`.
