How can i pass 'password' arguments to the passwd utility.

So rather than be prompted, I want to get through passwd with one sweep.

I.e. passwd -? [ password] username

Please advise.

Nothing in the man pages, its not built with such function to my knowledge. If you have an existing user though, use usermod which doesn't work like passwd and you can update the password with the -p option, etc.

Remember, man is your friend..

So 'usermod -p' does work for linux, however the '-p' parameter is not provided on a SunOS box v. 8.

There are two possible work arounds that I see.

1) How can I 'crypt' the password myself? ( then I can simply update /etc/shadow ).

2) How can I call the password utility, while passing the password and confirm password arguments? Let me see if I can explain this better... If you run 'passwd', you recieve prompts for data. I'm using Tcl/Tk for my app. How can I pass $value and $confirm_value to the 'passwd' utility and through the prompts while using tclsh?

Please advise.

I've determined it cannot be done on SunOS - Solaris 8. 'usermod' does not have the -p option. I had to right a c utility, with the 'crypt' function.
