Description

The sys-admin library is a unified, cross platform replacement for the Etc module.

Installation

gem install sys-admin

Synopsis

require 'sys/admin'
include Sys

# Returns an Array of User objects
a = Admin.users

# Returns an Array of Group objects
g = Admin.groups

# Get information about a particular user
p Admin.get_user("nobody")

# Get information about a particular group
p Admin.get_group("adm")

Admin

Admin.get_login

Returns the user name (only) of the current login.

Admin.get_user(name, options = {}) Admin.get_user(uid, options = {})

Returns a User object based on +name+ or +uid+. The +options+ hash is
for MS Windows only, and allows you to restrict the search based on the
options you provide, e.g. 'domain' or 'localaccount'.

Admin.get_group(name, options = {}) Admin.get_group(gid, options = {})

Returns a Group object based on +name+ or +uid+. The +options+ hash is
for MS Windows only, and allows you to restrict the search based on the
options you provide, e.g. 'domain' or 'localaccount'.

Admin.groups(options = {})

Returns an Array of Group objects.

The +options+ hash is for MS Windows only, and allows you to restrict the
search based on the options you provide, e.g. 'domain' or 'localaccount'.

Admin.users(options = {})

Returns an Array of User objects.

The +options+ hash is for MS Windows only, and allows you to restrict the
search based on the options you provide, e.g. 'domain' or 'localaccount'.

Developer's Notes

MS Windows

The Windows version now uses a win32ole + WMI approach to getting
information.  This means that the WMI service must be running on the
target machine in order to work (which it is, by default).

UNIX

The underlying implementation is similar to core Ruby's Etc implementation.
But, in addition to the different interface, I use the re-entrant version
of the appropriate functions when available.

Future Plans

Make the User and Group objects comparable.
Add ability to add, configure and delete users on Unix platforms.

Known Bugs

None that I'm aware of. If you find any, please log them on the project
