🔧 Define Custom IRB Commands

Extend IRB with your own commands for repetitive tasks. Here’s how to add a my_ls command that lists directory contents.

# ~/.irbrc
module IRB::ExtendCommandBundle
  def my_ls(path = '.')
    puts Dir.entries(path)
  end
end

Now inside IRB call my_ls 'lib' to quickly inspect files.
