i need to write a shell script that first comes up with a menu giving 4 options. Firstly ' 1) display a list of current users' ; ' 2) display a list of all files including hidden files in the home directory(i believe using the ls -a command)' ; 3) output a calender for the current month( i believe using the 'cal' command)' ; 4) and finally to be able to quit the script. The user can choose these options from a menu. I have be trialing many techniques, but with no luck! If anyone can help it would be much appreciated!
