showkey command in Linux with Examples
  • Last Updated : 27 May, 2019

showkey command in Linux is used to examine the codes sent by the keyboard. showkey prints to standard output either the scan codes or the key code or the `ascii’ code of each key pressed. In the first two modes, the program runs until 10 seconds have elapsed since the last key press or release event, or until it receives a suitable signal, like SIGTERM, from another process. In `ascii’ mode the program terminates when the user types ^D.

Syntax:

showkey [-h|--help] [-a|--ascii] [-s|--scancodes] [-k|--keycodes]

Example: This will examine the codes sent by the keyboard.

sudo showkey

Options:

  • showkey -h: This option prints to the standard error output its version number, a compile option and a short usage message, then exits.
    sudo showkey -h

  • showkey -s: This option starts showkey in scan code dump mode.
    sudo showkey -s

  • showkey -k: This option starts showkey in keycode dump mode. This is the default when no command line options are present.
    sudo showkey -k

  • showkey -a : This option will start showkey in `ascii‘ dump mode.
    sudo showkey -a
