[SOLVED] How to create password with -p option?

To create username test2 with command :
useradd -s /usr/bin -d /home/test2 test2
and to create the passwd.
passwd test2

Why can't write them into : useradd -s /usr/bin -d /home/test2 -p test2

The answer is inside your machine. Enter this in a terminal:

Code:

man useradd
man passwd

GNU/LInux documentation is ample for a new user to begin learning and using, just use the "man" command.

Hope that helps. Good luck.

useradd -s /usr/bin -d /home/test3 -p passwd test3

NOTE: the password specified by the -p option of useradd must already be encrypted...

Code:

       -p, --password PASSWORD
           The encrypted password, as returned by crypt(3). The default is to
           disable the password.

           Note: This option is not recommended because the password (or
           encrypted password) will be visible by users listing the processes.

           You should make sure the password respects the system's password
           policy.

And note that the "crypt(3)" is for DES passwords only, and is insecure. It is much better to use the passwd utility.
