Removing files in directtories

Ruby
1

Almost there… I’ve included line 7 as I’d like to be able to remove
files from a directory using code blocks. Commented it out for now
until I can work out how it’s done. Suggestions appreciated.

#!/usr/bin/ruby -w
def back_up
backdir = ENV[“HOME”] + “/foo/”
puts “about to backup some files and tar them into ~/foo”
puts “listing data in ~/foo”
Dir.foreach(backdir) {|file_names|

File.delete("#{backdir}" + file_names)

puts File.directory?
file_names }
end
back_up

def back_up
backdir = ENV[“HOME”] + “/foo/”
puts “about to backup some files and tar them into ~/foo”
puts “listing data in ~/foo”

Dir.foreach(backdir) { |name|
name = File.join( backdir, name )
if File.file?( name )
yield name
end
}
end

back_up { |file_name|
puts file_name
}

I wrote the following empty method as an extension to the builtin Dir
class. It iterates through a directory deleting all files and
directories, leaving the top level directory untouched.

class Dir

def empty()
self.each { |f|
if f !~ /^(.{1,2})$/
file = File.join(self.path, f)

    if File.stat(file).file?
      File.delete(file) rescue nil;
    elsif File.stat(file).directory?
      d = Dir.new(file)
      d.empty()
      Dir.delete(file) rescue nil;
    end
  end
}

end

end

I’m not sure what you want, but you might want to consider this:

printing:
ruby -r find -e ‘Find.find( File.join( ENV[“HOME”], “foo” ) ) {|f| puts
f}’

deletion:
ruby -r fileutils -e ‘FileUtils.rm_rf( File.join( ENV[“HOME”], “foo” )
)’

Kind regards
