Baby-sitting bash script using DVD drive

Question

This is the script I wrote to make an automated POC baby-sitter in 5 lines.

I first found this on a GIF or meme site and thought of making a POC script that does the same.

#How Linux users babysit
while : 
do
    eject
    eject -t
done

I don't know aything about bash. So, I want improvements.

You can find the origin and the script at https://linuxandstuff.wordpress.com/2015/11/21/messing-with-the-dvd-drive-in-command-line/

Answer 1

These days a -T (toggle) argument exists. That allows us to make this a lot neater:

watch -n0 eject -T

You can alter the delay between rocks by changing the -n0 argument.

watch is used to run any designated command at regular intervals.
