Today One BE final year student just asked me this one on IM, for his benefit and anyone who might want to have a password wrapper(if at all!!) here it is how to do the same via a shell script,
###This is a simple bash screipt to read password###
######without echoing the same on console#####
while [ $failed -le 3 ]
read -s -p "Password: " userpasswd
if [ "$userpasswd" == "$actual" ]
echo "Password accepted"
echo "Sorry! Wrong password, Try again..!!"
failed=$(( $failed + 1 ))
