It is not supporting ksh? Where did you read that?

root@isau02:/data/tmp/testfeld> cat mach.ksh
#!/usr/bin/ksh

echo "Some menue"
echo

PS3="Choose a number: "

select CHOICE in one two three four quit
do
  case $CHOICE in
        one)    echo 1;;
        two)    echo 2;;
        three)  echo 3;;
        four)   echo 4;;
        quit)   exit ;;
        *)  echo "\nTry again\n";;
  esac
done

exit 0

Seems it supports ksh. I used "select" which is not available in bash afaik.

Hi Zaxxon ,

Thanks For the Reply.. as i said i can't go for Shc as it is not installed in my server . I am getting error message when i use shc.
Sorry for my misinterpretation that it is not supported by ksh.Since it is not installed in my server i thought wrong.

Yes I saw that you don't have it installed. But showing it works with ksh could have made you installing/compiling it or something so.. :slight_smile:
I know no alternative. Maybe write it in perl and compile it with perlcc or directly in C. Maybe someone else comes up with another suggestion.
