Rm -rf

How do I do the equivalent of a Unix rm -rf directory command?

(This is for a GNU/Linux box.)

Thanks,

I’m curious, rm -rf will just as well work for a GNU/Linux box, so I guess
you don’t simply want to execute this as a shell command from your Ruby
script with rm -rf <dir>?

Right, for some reason I’m against using system or back ticks today.

Hi,

dirs =
Dir.glob(“#{path}/**/{.[^.],…?,}*”) do |f|
if File.directory?(f)
dirs << f
else
File.unlink(f)
end
end
dirs.reverse_each(&Dir.method(:rmdir))

How about FileUtiles.rm_rf in fileutils.rb?

It is kind of weird that there is a Dir.delete method that throws an
exception when the dir isn’t empty, but that there isn’t a Dir method that
allows you to delete one that isn’t. Isn’t that overly cautious?

The code will try to remove all files other than directory
first.
