bin/rails vs rails differences?

Several commands in the Intro Rails course use "bin/rails" as the prefix, instead of rails: for example, bin/rails generate [name of model]. This tutorial uses "rails generate" instead. What is the reason for using the "bin" in front of rails commands? This is something that is rather difficult to google, for whatever reason.

Thanks

The reason behind the bin/rails bin/rake is for speed. Command "time bin/rails s" you will every time you pass the command. The file will load faster.

Hi Ross Litzenberger ,

Is the command treated any differently with bin in front? And why is it faster?

Thanks

The reason behind bin/rails vs rails is different versions of rails. If you're running a current version of rails then it's fine to use the 'rails' command. But if you have a different version (say Rails 3.2) and you have Rails 4 installed then you need to use 'bin/rails' because you may run into issues with the 'rails' command.
