Description

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

Installation

gem install sys-admin

Adding the trusted cert

gem cert --add <(curl -Ls https://raw.githubusercontent.com/djberg96/sys-admin/main/certs/djberg96_pub.pem)

Synopsis

require 'sys/admin' # or 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")
p Admin.get_user("nobody", :localaccount => true)

# Get information about a particular group
p Admin.get_group("adm")
p Admin.get_group("adm", :localaccount => true)

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.

OSX

The slowdown for collecting lastlog information on OSX seems to have gotten progressively worse over time. Do not be surprised by significant slowdowns if you opt to collect it.

Future Plans

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