evtest

`evtest` is a command-line utility in Linux that captures input from devices like keyboards, bypassing graphical environments such as X11 or Wayland. It operates directly with `/dev/input` directory, allowing it to work without a GUI. Installation is straightforward via package repositories, and use requires listing devices and running `evtest` with a device path. It's highly useful for diagnostics and debugging in Linux, offering real-time feedback and a way to monitor raw keyboard inputs efficiently.
