(adsbygoogle = window.adsbygoogle || []).push({}); i am trying to make a script for the linux command line and i have hit a dead end.

I want this script to give an option like


i know i can use "echo" or "printf"

    echo "Options:"

echo "1) I am On Linux"

echo "2) I am On Windows"

echo "3) About"

echo "4) Quit"

But i want each option to call (open/run) a different file...
Option 1 would open the "linux.sh" file and option 2 would open the "windows.sh" file.
Option 3 would go to the about section of the script and option 4 would exit the script.

i know on windows you can use the

    goto 1

command but i cannot find the unix/linux equivalent to that command that can call (open/run) a different file.

Could Someone please reffer me to somewhere that can help me with it or write the script for me?
