Thanks you all,

Again I see that this printf we can use. But there are some scenarios where the o/p does not exactly match with echo. So still its good to have a way to pirnt -n /-e/-E with echo. Can this be considered as bug and can this be fixed?

Thanks & Regards

echo()
{
builtin printf "%s\n" "$*"
}

You can make this more elaborate if you want.
