The pathname depends on OS: Unix, Windows, etc. Pathname library works with pathnames of local OS. However non-Unix pathnames are supported experimentally." - !ruby/struct:SM::Flow::P body: It does not represent the file itself. A Pathname can be relative or absolute. It's not until you try to reference the file that it even matters whether the file exists or not. - !ruby/struct:SM::Flow::P body: Pathname is immutable. It has no method for destructive update. - !ruby/struct:SM::Flow::P body: The value of this class is to manipulate file path information in a neater way than standard Ruby provides. The examples below demonstrate the difference. <b>All</b> functionality from File, FileTest, and some from Dir and FileUtils is included, in an unsurprising way. It is essentially a facade for all of these, and more. - !ruby/struct:SM::Flow::H level: 2 text: Examples - !ruby/struct:SM::Flow::H level: 3 text: "Example 1: Using Pathname" - !ruby/struct:SM::Flow::VERB body: " require 'pathname'\n p = Pathname.new(&quot;/usr/bin/ruby&quot;)\n size = p.size # 27662\n isdir = p.directory? # false\n dir = p.dirname # Pathname:/usr/bin\n base = p.basename # Pathname:ruby\n dir, base = p.split # [Pathname:/usr/bin, Pathname:ruby]\n data = p.read\n p.open { |f| _ }\n p.each_line { |line| _ }\n" - !ruby/struct:SM::Flow::H level: 3 text: "Example 2: Using standard Ruby" - !ruby/struct:SM::Flow::VERB body: " p = &quot;/usr/bin/ruby&quot;\n size = File.size(p) # 27662\n isdir = File.directory?(p) # false\n dir = File.dirname(p) # &quot;/usr/bin&quot;\n base = File.basename(p) # &quot;ruby&quot;\n dir, base = File.split(p) # [&quot;/usr/bin&quot;, &quot;ruby&quot;]\n data = File.read(p)\n File.open(p) { |f| _ }\n File.foreach(p) { |line| _ }\n" - !ruby/struct:SM::Flow::H level: 3 text: "Example 3: Special features" - !ruby/struct:SM::Flow::VERB body: " p1 = Pathname.new(&quot;/usr/lib&quot;) # Pathname:/usr/lib\n p2 = p1 + &quot;ruby/1.8&quot; # Pathname:/usr/lib/ruby/1.8\n p3 = p1.parent # Pathname:/usr\n p4 = p2.relative_path_from(p3) # Pathname:lib/ruby/1.8\n pwd = Pathname.pwd # Pathname:/home/gavin\n pwd.absolute? # true\n p5 = Pathname.new &quot;.&quot; # Pathname:.\n p5 = p5 + &quot;music/../articles&quot; # Pathname:music/../articles\n p5.cleanpath # Pathname:articles\n p5.realpath # Pathname:/home/gavin/articles\n p5.children # [Pathname:/home/gavin/articles/linux, ...]\n" - !ruby/struct:SM::Flow::H level: 2 text: Breakdown of functionality - !ruby/struct:SM::Flow::H level: 3 text: Core methods - !ruby/struct:SM::Flow::P body: "These methods are effectively manipulating a String, because that's all a path is.
