What is Ruby s equivalent of Python s sys executable

In Ruby, finding the equivalent of Python's sys.executable is a bit different, as Ruby doesn't have a built-in module like sys for accessing low-level system information. However, you can achieve a similar result by using various methods provided by Ruby's standard library and system commands. In this tutorial, we'll show you how to find Ruby's equivalent of Python's sys.executable. Ruby provides the RbConfig module, which gives you access to configuration information about the Ruby installation, including the path to the Ruby interpreter. You can use this module to find the path to the currently executing Ruby executable. Here's how you can do it: The RbConfig.ruby method returns the path to the Ruby interpreter being used. Another way to obtain the path to the Ruby executable is by using the Gem module, which is included with Ruby by default. You can use Gem.ruby to get the path to the Ruby interpreter: This method is essentially equivalent to using RbConfig.ruby and is a convenient way to find the Ruby interpreter. If you prefer a more general approach, you can use a system command to determine the Ruby executable. On most Unix-like systems, you can use the which command, and on Windows, you can use the where command. You can use the backticks or %x{} notation to execute system commands in Ruby: On Unix-like systems (Linux, macOS, etc.): On Windows: Please note that using system commands may not work if the Ruby interpreter is not in the system's PATH or if the command is not available on the system. In Ruby, there isn't a direct equivalent of Python's sys.executable, but you can find the path to the Ruby interpreter using the methods provided by the RbConfig or Gem modules, or by executing system commands. Each of these methods has its own advantages and limitations, so choose the one that best suits your needs. ChatGPT
