NEWUSERS(8) System Management Commands

NEWUSERS(8)

NAME

newusers - update and create new users in batch

SYNOPSIS

newusers [options] [file]

DESCRIPTION

The newusers command reads a file (or the standard input by default)

and uses this information to update a set 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 exceptions explained below:

pw_name:pw_passwd:pw_uid:pw_gid:pw_gecos:pw_dir:pw_shell

pw_name

This is the name of the user.

It can be the name of a new user or the name of an existing user

(or an user created before by newusers). In case of an existing

user, the user's information will be changed, otherwise a new

user

will be created.
