Create github action to test the shell scripts

Lets create a github action scripts to check if the shell scripts work and if a newly added one work as well.

This script has an output, which shows a text menu with few options 1,2,3..

What I want to do!!!

I want to run this script automatically and automatically selects option 2 on every start/reboot of Linux system.

Bash Menu Script Example

PS3='Please enter your choice: '
options=("Option 1" "Option 2" "Option 3" "Quit")
select opt in "${options[@]}"
do
case $opt in
"Option 1")
echo "you chose choice 1"
;;
"Option 2")
echo "you chose choice 2"
;;
"Option 3")
echo "you chose choice 3"
;;
"Quit")
break
;;
*) echo invalid option;;
esac
done

Output is as follows:
"Choose your option:"

1. Option 1
2. Option 2
