Try browsing through the methods of File and Dir in the docs:

[http://www.ruby-doc.org/core/](http://www.ruby-doc.org/core/)

Hope that helps.

Here’s the website I use:  
[http://www.rubycentral.com/ref/](http://www.rubycentral.com/ref/)

Check out Dir and File

Here’s some sample code I’ve been tinkering with that should get you  
started.

def findDirs (thisDir)  
Dir.entries(thisDir).each { |x|  
next if [“.” , “…”].include? x  
thisFile = File.join(thisDir,x)  
case File.ftype(thisFile)  
when “directory”  
puts "Found a directory: "+thisFile  
findDirs(thisFile)  
when “file”  
#puts "Found a file! "+File.join(thisDir, x)  
end  
}  
end

DirHelper.new.findDirs(ARGV[0])  
end

Try Dir and File:

my\_dir = Dir[“C:/workspaces/Source/\*\*/\*.rb”] # collect all the  
ruby files recursively  
my\_dir.each do |filename|  
puts filename  
File.open(filename, “r”) do |f|  
puts f  
end  
end

Here’s a good place to start:

[http://ruby-doc.org/docs/ProgrammingRuby/](http://ruby-doc.org/docs/ProgrammingRuby/)

Look for Dir and File.

How can I display the content of a folder after some time of its  
creation, in order to see the newly added files?  
Any script with File.readlines? any help?
