newusers - update and create new users in batch
newusers reads a file of user name and clear-text password pairs and
uses this information to update a group of existing users or to create
new users. Each line is in the same format as the standard password
file (see passwd(5)) with the following exceptions:
This field will be encrypted and used as the new value of the
pw_age This field will be ignored for shadow passwords if the user
pw_gid This field may be the name of an existing group, in which case
the named user will be added as a member. If a non-existent
numerical group is given, a new group will be created having
pw_dir This field will be checked for existence as a directory and a
new directory with the same name will be created if it does not
already exist. The ownership of the directory will be set to be
that of the user being created or updated.
This command is intended to be used in a large system environment where
many accounts are updated at a single time.
The input file must be protected since it contains unencrypted
shadow password suite configuration
login.defs(5), passwd(1), useradd(8).
