How to read files in all subdirectories?

Ruby experts:

I know how to read each file in a subdirectory using the code below. My question is: How can this code be modified so that the code will, in addition, read each file in all subdirectories below “some_directory”?

(I think what I want is a way to read all subdirectories “recursively”.)

Thanks in advance!

Dir.new("./some_directory").each { |fname|
if (File.file? “./some_directory/”+fname)
File.open("./some_directory/"+fname) { |file|
do_stuff_here
}
end
}

Dir[‘./some_directory/**/*’]

Hi,

Use zsh style recursive wildcard:

for f in Dir.glob(“./some_directory/**/*”)
File.open(f) { |file|
do_stuff_here
} if File.file?(f)
end

Use the Find module, as per the following example.

Recurse into directories given on the command-line, printing the name of

each file, ignoring CVS directories, and adding / to directories.

require “find”
dirs = ARGV || [“.”]
Find.find(*dirs) do |path|
Find.prune if File.basename(path) == “CVS”
print path
print “/” if File.stat(path).directory?
print “\n”
end

Thanks in advance!
