How to detect keystrokes?

  • 772

I have a script running always at the background. Inside that script I have to write the codes to detect keystrokes, and once a particular keystroke is detected, the rest of the script must be executed. How can I do this?

I have tried the showkey command but failed to add that to my script.

command-line

  1. you can read the keystrokes by the read command for this use the following bash script

    #! /bin/bash
read -s -n 1 key # -s: do not echo input character. -n 1: read only 1 character (separate with space)
if [[ "$key" == "your key" ]];then
    #your script here
fi

    you can experiment with the read command and some bash scripts
