The command "rbenv local ${version}" is used with rbenv, which is a Ruby version management tool.

Here's an explanation of each part of the command:

• "rbenv": This is the rbenv command, which is used to manage different versions of Ruby on a single machine. It allows you to switch between different Ruby versions based on your project requirements.
• "local": This is a command option in rbenv. When used with "rbenv local", you can specify the Ruby version you want to set locally for a specific project or directory.
• "${version}": This is a placeholder representing the specific Ruby version number. You need to replace ${version} with the actual Ruby version number you want to set as the local version for your project. For example, if you want to set Ruby version 2.7.2 as the local version, use the command "rbenv local 2.7.2".

By running the "rbenv local ${version}" command, you are instructing rbenv to set the specified Ruby version as the local version for your current project or directory. This means that whenever you navigate to this project's directory in your command line or terminal, rbenv will automatically switch to the specified Ruby version for all Ruby-related operations within that directory.
