Is there any shell script command  which will echo the password entered but  will show only "*" signs?

Hi janu_s,

stty -echo

man stty

while it will not do exactly what you want (the *s)
but it will let you read a password

How about dialog?
# $Id: password,v 1.2 2003/08/15 19:40:37 tom Exp $
: ${DIALOG=dialog}

tempfile=`tempfile 2>/dev/null` || tempfile=/tmp/test$$
trap "rm -f $tempfile" 0 1 2 5 15

$DIALOG --title "INPUT BOX" --clear \
        --passwordbox "Hi, this is an password dialog box. You can use \n
this to ask questions that require the user \n
to input a string as the answer. You can \n
input strings of length longer than the \n
width of the input box, in that case, the \n
input field will be automatically scrolled. \n
You can use BACKSPACE to correct errors. \n\n
Try entering your name below:" 16 51 2> $tempfile


case $retval in
    echo "Input string is `cat $tempfile`";;
    echo "Cancel pressed.";;
    if test -s $tempfile ; then
      cat $tempfile
      echo "ESC pressed."
