Answer 1

Following @karl-li 's suggestion in @theIV solution, I found this to work well:

Dir.entries('path/to/files/folder').reject { |f| File.directory?(f) }

Answer 2

Dir.glob('*').select { |fn| File.file?(fn) }

Answer 3

In addition to Mark's answer, Dir.entries will give back directories. If you just want the files, you can test each entry to see if it's a file or a directory, by using file?.

Dir.entries('/home/theiv').select { |f| File.file?(f) }

Replace /home/theiv with whatever directory you want to look for files in.

Also, have a look at File. It provides a bunch of tests and properties you can retrieve about files.

Answer 4

Entries don't do rescursion i think. If you want the files in the subdirs also use

puts Dir['**/*'].select { |f| File.file?(f) }

Answer 5

It sounds like you're looking for Dir.entries:

Returns an array containing all of the filenames in the given directory. Will raise a SystemCallError if the named directory doesn’t exist.

If searching Google for how to solve this problem isn't turning up any results, you can look through the Ruby documentation.

Answer 6

If you want to do it in one go instead of first creating an array and then iterating over it with select, you can do something like:

my_list = []
Dir.foreach(dir) { |f| my_list << f if File.file?(f) }
