creating a menu

[Norman_21]

I've created a menu with different options, but I used the esac at the end of the script which force me to log off after taking an option. Could anyone please advise to change the script to take me back to the menu after executing an option from the menu.
here is an example:
i.e.)
echo " 1. who am I"
echo " who is login"
echo " enter your choice \c:"
read VAR
case $VAR in
1) whoami
;;
2) finger|pg
;;
* ) echo " you have not entered a valid option"
esac
echo "end of program

Hi

simply create a while-loop that is always true:

while true
do

echo " 1. who am I"
echo " who is login"
echo " enter your choice \c:"
read VAR
case $VAR in
1) whoami
;;
2) finger|pg
;;
3) exit
;;
* ) echo " you have not entered a valid option"
esac

done

Hi,
you can put a until-do-done construction around it like:

VAR=0
until (( VAR = 3 ))
do
case
add an option 3 exit ;;
done

Good luck

hi,

you already have the solution in the above replies.

to add on to them, a piece of code that i frquently use:
=============================
ANSW="X"
until [ $ANSW = "Y" -o $ANSW = "N" -o $ANSW = "y" -o $ANSW = "n" ] 2> /dev/null
do
echo "Do you want to continue?\c "
read ANSW
ANSW=${ANSW:-n}
done
=============================

Hope this helps too!

Best Regards
Yogeeraj

Chris, Donald,
Thanks guys for the quick support.

Yojeeraj,

My man Yojeeraj, do I add it right under each option!
appreciate your advise.

Hi:

Instead of checking input from a 'read' for uppercase and lowercase strings, declare the receiving variable of the read like this:

# typeset -l VAR

Now uppercase letters are converted to lowercase ones and you only need test for the lowercase variant.

Conversely, if you wsnt to convert all lowercase characters to uppercase characters, use:

# typeset -u VAR

Regards!
