The ri documentation for FileUtils.rm gives several examples, among which you 
can find this:

FileUtils.rm Dir.glob('*.so')

This removes all files with extension .so from the current directory. To 
remove *all* files from the current directory, you need to replace '*.so' with 
'*' (which matches all file names):

require 'fileutils'
FileUtils.rm Dir.glob('*')

If you want to remove all files from another directory, you do:

require 'fileutils'
FileUtils.rm Dir.glob('/path/to/dir/*')

Note that this will give you errors in case the directory also contains 
subdirectories. In this case, the correct approach depends on what you want to 
obtain
* if you also want to remove the subdirectories, replace FileUtils.rm with 
FileUtils.rm_r, which also remove directories
* if you don't want to touch subdirectories and their content, you can do 
something like this:

Dir.glob('*').each do |f|
  FileUtils.rm f unless File.directory? f
end

* if you want to delete the files in the subdirectories but keep the empty 
subdirectories, you can do this:

require 'find'
Find.find('.') do |f|
  next if File.directory? f
  FileUtils.rm f
end

I hope this helps
