Simple choice script

quack322 · 08-14-2004, 07:22 PM

I need the basics of a simple shell script that gives the user a choice. For example

1) Restart
2) Shutdown
3) Logoff
Enter choice:

I do not want to use any "dialog" for this script

--Thanks

Ask google for "advanced bash". This is the best doc I know.
I also look often at startup scripts in /etc/init.d when I don't remember some constructs.

Code:

#!/bin/sh

cat << _EOF_
1) Restart
2) Shutdown
3) Logoff
_EOF_

while [ 1 ] ; do
  echo -n "Enter choice and hit enter: "
  read CHOICE
  case "$CHOICE" in
    1 )
      echo "execute restart"
      exit
      ;;
    2 )
      echo "execute shutdown"
      exit
      ;;
    3 )
      echo "execute logoff"
      exit
      ;;
  esac
done
