Full Discussion: Create new user account and password in shell script
Top Forums Shell Programming and Scripting Create new user account and password in shell script Post 302387982 by killuane on Tuesday 19th of January 2010 04:45:51 AM
Old 01-19-2010
On Solaris I have tried:

1) redirecting the input as follows:

Code:
passwd $NEW_USER_ID <<EOF
> $NEW_PASSWD
> $NEW_PASSWD
> EOF

but I get prompted to enter the password interactively:
New Password:
2) putting the passwords into a file

Code:
echo $NEW_PASSWD >> tempfile
echo $NEW_PASSWD >> tempfile

then tried to redirect the contents of that file into the passwd command:

Code:
passwd $NEW_USER_ID < `cat tempfile`

from which I get the error:
ksh: $NEW_PASSWD^J$NEW_PASSWD: cannot open
(the error actually shows the real password not the environment variable)

or:

Code:
passwd $NEW_USER_ID < tempfile

but again I get prompted to enter the password interactively:
New Password:
3) write a mini shell script:

Code:
sleep 1
echo $NEW_PASSWD
sleep 1
echo $NEW_PASSWD

then tried to execute that script and pipe the output to the passwd command:

Code:
./script | passwd $NEW_USER_ID

but again I get prompted to enter the password interactively:
New Password:
So, it looks to me like my attempts to redirect stdin to the passwd command are failing but I don't know any other way to do it.

yppasswd

yppasswd(1)						      General Commands Manual						       yppasswd(1)

NAME

       yppasswd - change password in Network Information Service (NIS)

SYNOPSIS

       yppasswd [name]

DESCRIPTION

									  Note

       If Enhanced Security is enabled on your system, use the passwd command to change your password, even if NIS is in use.

       The  yppasswd command lets you change your password in the Network Information Service (NIS) map, a network data base service.  Only you or
       the superuser can change your NIS password.

       When you enter the yppasswd command, the program prompts you for the old password and then for the new password. Note  that  the  passwords
       are not displayed on the screen.

       Next,  the  program asks you for the new password again, to verify that you have typed it correctly.  If you do not type the passwords cor-
       rectly, you will receive an error message after you enter the new password.

       Your new NIS password must meet one of the following requirements: It must be a combination of at least six alphanumeric characters, or	It
       must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence.

									  Note

       The passwd command does not change the NIS password.  This command only changes the local password file (/etc/passwd), and not the NIS mas-
       ter password file.

ERRORS

       Your new password does not meet the minimum length requirement.	You misspelled your new password or its verification.  Your  new  password
       can not be activated. It must be different from your old password and your login name.

FILES

       Password file NIS directory
