rbenv: Display all Ruby versions that contain the specified executable.

rbenv

$ rbenv whence ${executable}

try on your machine

The command "rbenv whence ${executable}" is used to determine the location of a Ruby executable in the rbenv installation.

Here's how it works:

"rbenv" is a command-line tool used for managing multiple installations of the Ruby programming language. It allows you to have multiple versions of Ruby installed on your system and easily switch between them.
"whence" is a subcommand provided by rbenv. It is used to find the full file path of a Ruby executable.
${executable} is a placeholder representing the name of the Ruby executable you want to find. You need to replace it with the actual name of the executable you're looking for (e.g., "ruby", "gem", "rake", etc.).

When you run the command, rbenv searches through the directories where Ruby executables are installed (including different Ruby versions) and returns the full file path of the specified ${executable}. This helps you identify the exact binary that will be executed when you run that command.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
