NAME

6       newusers - update and create new users in batch
7

SYNOPSIS

9       newusers [new_users]
10

DESCRIPTION

12       newusers reads a file of user name and clear-text password pairs and
13       uses this information to update a group of existing users or to create
14       new users. Each line is in the same format as the standard password
15       file (see passwd(5)) with the following exceptions:
16
17       pw_passwd
18          This field will be encrypted and used as the new value of the
19          encrypted password.
20
21       pw_age
22          This field will be ignored for shadow passwords if the user already
23          exists.
24
25       pw_gid
26          This field may be the name of an existing group, in which case the
27          named user will be added as a member. If a non-existent numerical
28          group is given, a new group will be created having this number.
29
30       pw_dir
31          This field will be checked for existence as a directory and a new
32          directory with the same name will be created if it does not already
33          exist. The ownership of the directory will be set to be that of the
34          user being created or updated.
35
36       This command is intended to be used in a large system environment where
37       many accounts are updated at a single time.
38
39       Default encryption algorithm is DES, but this setting can be changed in
40       /etc/login.defs. Red Hat uses MD5 to encrypt passwords by default.
41

CAVEATS

43       The input file must be protected since it contains unencrypted
44       passwords.
45

FILES

47       /etc/login.defs
48          Shadow password suite configuration.
