Need one line command to create and set password for new user...

Using useradd abc --password password

WHAT exactly is your request?

I want one command in which I should be able to create a new user with password assigned to it (combination of useradd and passwd command)

One I have tried is
useradd abc --password password123

but it's not working

What is not working? man useradd :

It could be a help:

useradd test;echo <your_password> |chpasswd test

thanks nixhead..
