I just wrote a small script to find the files in current directory and
its child directories which include the word "ruby".
But it can't work, please help point out my error, thanks.
def myfind(path=".")
Dir.foreach(path) do |f|
if File.file? f
open(f) do |c|
puts "#{path}/#{f}" if c.read.scan(/ruby/)
end
elsif File.directory? f
newpath = File.join path,f
myfind(newpath)
end
end
end

Hi,
Walking the directory recursively can be done with 'glob', or it's equivalent method ''. The following will recursively find all files that have a '.rb' extension, starting from the current directory.
Dir['**/*.rb'].each { |path| puts path }
The scan method returns an array of matches, or takes a block which can act on that array. To check if any matches where found, one can check that the returned array is not empty, for example:

Thanks all.
Under all your helps, I finally get the script to work correctly.
def myfind(path=".")
Dir.foreach(path) do |f|
f = File.join(path,f)
## puts f
if File.file? f
open(f) do |c|
puts "#{f}" unless c.read.scan(/ruby/).empty?
end
elsif File.directory? f and File.basename(f) != "." and
File.basename(f) != ".."
myfind(f)
end
end
end

You just need a single match - not all of them.
end
elsif File\.directory? f and File\.basename\(f\) \!= "\." and
File.basename(f) != ".."
myfind(f)
end
end
end
myfind
It is easier if you use Find:
require 'find'
Find.find path do |f|
puts f if File.file?(f) && /ruby/ =~ File.read(f)
end
