Find.find and files in cwd

Brad Tilley

3/21/2006 7:14:00 PM

I can use Find.find(Pathname.getwd) to get an array of all file paths
recursively, but how do I get only the files in the cwd (do not recurse
into sub-directories)?

Thank you,
Brad

Try:

Dir["#{Dir.getwd}/*"]

Hope that helps.

Check out Dir (http://ruby-doc.org/core/classe...)

Dir.pwd #=> current directory
Dir['*'] #=> contents of current directory (files and directories)

Try:

Dir["#{Dir.getwd}/*"]

Hope that helps.

Yes, that helps... thank you. Perhaps I'm using it wrong though. When
trying to extract files with File.file? or links with File.link? like this:

Dir["#{Dir.getwd}/*"].each do |path|
if File.file?(path)
puts path
end
end

I get the whole directory listing (files, links, folders, etc.)

To get only normal files try:
Dir["*"].delete_if{ |e| not File.file?( e ) }

To get only directories try:
Dir["*"].delete_if{ |e| not File.directory?( e ) }

To get only links try:
Dir["*"].delete_if{ |e| not File.link?( e ) }

The whole thing seems a bit hackish to me and it still leaves links to
files and links to folders on my Windows test machine.

I like this:
contents = Dir.entries(Pathname.getwd)

Better than this:
contents = Dir["#{Dir.getwd}/*"]

It makes more sense to me and seems more readable.

I wish that with either approach File.file? would work like this:

Dir.entries(Pathname.getwd).each do |entry|
if File.file?(entry)
puts entry
end
end

Why not:
Dir.entries(Dir.pwd).each do |entry|
unless File.directory?(entry)
puts entry
end
end

Or Dir.entries(Dir.pwd).reject { |entry| File.directory?(entry) }

Working with file globs is *not* hackish in my opinion. File globs are a powerful and wonderful thing. See Dir#glob for more
information.

Granted reject is better use then delete_if in this scenario. I like Logan's last solution, although to tidy it up:
Dir.entries( Dir.pwd ).reject{ |f| File.directory?( f ) }
