is there any way to check or test the input from a 'read' against a for 'loop'?
I don't want the case statement to execute there any of the input is incorrect. As of right now it will loop through, outputting the * ) branch multiple times while still executing the correct inputs.
echo "Select Your Options (Seperated by spaces): 1 2 3" read SELECTION # Test SELECTION here? Then exit if fail? IE, if a 4 is entered. for INPUT in $SELECTION; do case $INPUT in 1 ) echo "you selection option 1" ;; 2 ) echo "you selection option 2" ;; 3 ) echo "you selection option 3" ;; * ) echo "Check your selection. Anything outside the following will make this fail: 1 2 3 " RETVAL=1 exit ;; esac done
