Don't want to use useradd command to create a new user
I am doing manual addition of accounts. Actually I am writing a script and I am working on RedHat7.1 system. What I am trying to do is run the script and pass all the values of the username password and group as command line parameters. Now what I am trying to do is after passing the initial password I want the account to be activated with that password. Because if you simply edit the passwd file and add the username, password and other information when you test the account it does not recognize the account and then as a root user you have to go and enter the password again and then it gets written to the shadow file in encrypted form(even if you user command "pwconv" does not write the password to the shadow file in the encrypted form). P;us I can't leave the acconts open either. To create 500 account or more It will take me long a time to create those accounts. I just want to automate those password writing to the shadow file without having to go through this command
passwd <username>
enter new password in Unix ******
So, if anyone knows how can I do this through the script please let me know.
regards

pwconv

pwconv(1M)                                                System Administration Commands                                                pwconv(1M)

NAME

       pwconv - installs and updates /etc/shadow with information from /etc/passwd

SYNOPSIS

       pwconv

DESCRIPTION

       The pwconv command creates and updates /etc/shadow with information from /etc/passwd.

       pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is
       already in /etc/shadow and should not be modified.

       If the /etc/shadow file does not exist, this command will create /etc/shadow with  information  from  /etc/passwd.  The  command  populates
       /etc/shadow  with  the  user's  login  name,  password,  and  password  aging  information. If password aging information does not exist in
       /etc/passwd for a given user, none will be added to  /etc/shadow. However, the last changed information will always be updated.

       If the  /etc/shadow file does exist, the following tasks will be performed:

                Entries that are in the  /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file.

                Entries that are in the  /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow.

                Password attributes (for example, password and aging information)  that exist in an /etc/passwd entry will be moved to the  corre-
                sponding entry in  /etc/shadow.

       The pwconv command can only be used by the super-user.
