What does bundle mean?

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem
is installed.

Answer 1

subl : subl is the command-line command to launch Sublime Text on OS X.

gem : is a packaged Ruby application or library(third-party code as you just installed) .

Gemfile : It is files allow you to specify what gem dependencies are needed for your Rails application.

Bundler manages an application's dependencies.

Refer Bundler , Sublime

Answer 2

The Gemfile is a list of code your program needs. In Ruby, to be cute, we call these gems. So there are gems to do things like read HTML, and if you wanted to use it, you would put it in your Gemfile.

Saying subl Gemfile means that you are opening the Gemfile with the Sublime text editor. You don't need the sublime text editor, you can use any text editor you like. For you probably try nano or pico ( nano Gemfile and pico Gemfile ) or if you don't want to edit the files in your terminal, your OS almost certainly has one you can use (on Windows, there is Notepad and on Mac TextEdit). It would be wise to get an editor that can understand and highlight code, though.
