Thread: Case Command Syntax Works in Unix, not Linux - Help!

I have a script that works well in Unix. The syntax is as follows:

Code:

menu_1 () {

    Command 1
    Command 2
}

menu_2 () {
    Command 1
    Command 2
}

while :
do
cat << !

Please select:

1. Menu 1
2. Menu 2
3. Quit

!

echo "Your choice? : "
read choice

case $choice in
1) menu_1;;
2) menu_2;;
3) quit;;
*) echo "\"$choice\" is not valid "; sleep 2;;
esac
done

However, when I try to the case command in the same way under Linux, I get a series of syntax errors that reference either the closing } or any line that starts off with "Menu." Removing the case command and menu options from the script and it works fine. Can anyone help me or point me to a good tutorial that uses case in Linux for building a menu?

Thank you kindly for your help.

That code works perfectly well in Linux. Are you sure you are using a Bourne-type shell (bash, dash, pdksh, ksh93).

Try putting a shebang line at the top of your file:

Code:

#!/bin/sh

Post the exact error mesages you get if you continue to have problems.
