Dear All

I am writing a simple shell script of menu options. Here is an extract:
echo " Press 1-5 or 9, then press Enter [ ]"
echo ""
read i

What I would like to do is arrange for the cursor to be after the word Enter ans between the [ and ].

Is this possible?

Thanks and wait to hear

Stephanos

Noop. Shell lacks cursor movement, try something as follows:

Code:

 read -p "Press 1-5 or 9, then press Enter : " i

However, you can jazz up a bit using dialog utility from a shell script and it works with cli as well as GUI

Code:

dialog --menu "Select choice" 15 30 3 1 Choice1 2 Choice2 3 Choice3 4 Choice4 5 Choice5 6 Exit

Here is a sample shell script:

Code:

#!/bin/bash
ansfile=/tmp/file.$$
height=15
width=40
menu_height=5
title="Main Menu"
dialog  --clear \
    --title "$title" \
    --menu "Select choice" $height  $width $menu_height  \
    1 "Choice1" \
    2 "Choice2" \
    3 "Choice3" \
    4 "Choice4" \
    5 "Choice5"  2>$ansfile

ret=$?
ans=$(cat $ansfile)

case $ret in
  0)
    echo "You selected $ans";;
  1)
    echo "[Cancel] key pressed.";;
  255)
    echo "[ESC] key pressed.";;
esac

/bin/rm -f $ansfile
