How to make a bash script which executes at startup of laptop automatically

homie4u

I have a laptop and one of it’s key is wrecked and by this it’s always pressed and stops me to do my work.. So on windows there are lots of application which disable specific key but on linux i use xmodmap - e “keycode <keyvalue>=”

But this work only when i run this code everytime after starting my laptop so i got an idea to make this above as a bash script which auto executes at startup time

HELP
