capsremap

Remaps Caps Lock to Enter at the kernel level via udev hwdb.

• Works on X11, Wayland, and TTY
• Persists across reboots and suspend/wake
• No extra packages required — just systemd (standard on all major distros)

Usage

sudo ./capsremap.sh install     # apply the remap (default)
sudo ./capsremap.sh uninstall   # remove the remap
sudo ./capsremap.sh status      # check if remap is active

The script will prompt for sudo automatically if not run as root.

How it works

Writes a hwdb rule to /etc/udev/hwdb.d/90-caps-to-enter.hwdb that remaps the Caps Lock scancode to Enter at the kernel input level, covering AT/PS2, USB, and Bluetooth keyboards. Changes take effect immediately via udevadm trigger.
