Running script at before halt time

Question

I know adding script in startup time. Is it possible, adding script in system shutdown time? For an example Whenever a user, shutdown their PC, I want a history -c command will run in the background so that the user's previous worked commands can be erasing in the terminal. Is it possible?

Answer 1

To execute a script at shutdown:

1. Put your script in /etc/rc6.d
2. Make it executable: sudo chmod +x K99_script
3. Notes:
   • The scripts in this directory are executed in alphabetical order.
   • The name of your script must begin with K99 to run at the right time.
