$ VI Users-list.txt

In a file, a user row, the following is the style:

Username:Password:User id:group id:user info:home directory:default ShellUsername:Password:User id:group id:user Info: Home directory:default ShellUsername:Password:User id:group id:user info:home directory:default Shell ...

Create user

After you have created a file that contains user information, use the newusers command to create the user.

# newusers Users-list.txt

Checking user accounts

Finally you can confirm that the user was created correctly and view them in the /etc/passwd file:

# TAIL/ETC/PASSWD
