CPU(8)                                                        System Manager's Manual                                                       CPU(8)

NAME

       cpu - A tool for user and group administration

SYNOPSIS

       cpu [OPTIONS]

DESCRIPTION

       CPU is a tool for user administration, that was initially based on FreeBSD's pw(8). This tool will allow you to administer users and groups
       on several different backends currently including LDAP and flat files. Please see the website http://cpu.sourceforge.net for more  informa-
       tion, or help improve the man page.

OPTIONS

       There are two kinds of options; options for CPU and options for CPU modules.  There are only four options for CPU, they are as follows:

       -C configfile, --config configfile
              The configuration file to be used by CPU. The options in this file are used for CPU modules.

       -h, --help
              Display help for CPU. If specified in conjunction with the -m option the help for that particular module is displayed.

       -M method, --method=method
              This  is  the method of administration. Current options are ldap or passwd (passwd is not yet working). This can be specified in the
              configuration file.

       -V, --version
              Display the version of the software.
