rails: Check current version of rails.
$ rails --version
try on your machine
The command "rails --version" is used to check the version of Ruby on Rails framework that is currently installed on your computer.
When you run this command in the command line, it will display the version number of Rails. For example, the output could be "Rails x.x.x", where "x.x.x" represents the version number.
This command is useful when you want to make sure that you have the correct version of Rails installed or when you need to check if an application requires a specific version of Rails.

never run a command you are not sure if it is safe.
