Unixium

The Unixium library provides the following useful functions for Unix systems:

• Access to a Unix-based system's user, shadow and group databases
• Obtain the Terminal size in rows and columns
• Lots more to come!

Note: This library is still being developed and will likely undergo various major changes over the coming months until we reach a stable release. Please use as a reference only at this point.

Installation

Add this to your application's shard.yml:

dependencies:
  unixium:
    github: fgimian/unixium.cr

Usage

require "unixium"

# Obtain all users on the system
Unixium::Users.all.each do |user|
  puts "Username: #{user.name}"
  puts "Password: #{user.passwd}"
  puts "UID: #{user.uid}"
  puts "GID: #{user.gid}"
  puts "GECOS: #{user.gecos}"
  puts "Home Directory: #{user.dir}"
  puts "Shell: #{user.shell}"
end

# Obtain an individual user by their username or uid
fots = Unixium::Users.get("fots")
fots = Unixium::Users.get(501)

# Obtain all groups on the system
Unixium::Groups.all.each do |group|
  puts "Name: #{group.name}"
  puts "Password: #{group.passwd}"
  puts "GID: #{group.gid}"
  puts "Members: #{group.members}"
end

# Obtain an group user by their name or gid
staff = Unixium::Groups.get("staff")
staff = Unixium::Groups.get(20)

# TODO: Add instructions on shadow usage when it's implemented

# Obtain the Terminal size
termsize = Unixium::Terminal.size
puts "Your terminal has #{termsize.rows} rows and #{termsize.columns} columns"
