Good Day,
Is there any way I could add an account with on line
And when user log in for the firt time he could pick his own password.

OR Is there any way I can add password in while adding user?
I have tried
But that doesn't make "dog1" password for user dog.

Note I have used "passwd" utility but here I need to do whole thing once, No prompts a answers.


Thank you.

It is possible to do this from the User Manager in one step. However the only way I know to do it from the command line requires two steps (useradd then passwd). The -p option on the useradd command uses an encrypted passwd. This is why your dog1 example did not work. It is possible to create a program to do it in one step using the crypt function. Here is a sample program. It isn't exactly what you want, but it will give you an idea of how crypt can be used with useradd in a C program.

There is a way to allow a user to login without a password, but it does not force them to set a password. This would be a security risk. It also takes two steps. One using useradd and the other modifying /etc/passwd.

^ Thank you for your solution.
Even more thanks for doing it in C.
There are things in you code which I would use as my starting point for sys-utilities coding in C.

Thanks once again.
