Feature #4189
closedFileUtils#ln_r
Description
=begin
I wrote a method for FileUtils to do recursive hard linking. It works just like cp_r but links instead of copies.
The code can be found along with the pull request I made to ruby/ruby on Github:
http://github.com/ruby/ruby/pull/4#issuecomment-631067
It's a pretty handy method for "staging" read-only files. For example I've used it to stage test fixture files in a tmp testing location and I've used it collect together a set of files for packaging into a tarball.

Since ln command does not have -r option, I am kind of hesitating to add ln_r. I understand usefulness of the method. But I am not sure yet where to add (is fileutils the best place?), and what to add (is ln_r the best name for the method?).

FYI
X11 distribution has lndir command, it creates real directories and file symlinks though.

GNU cp has the -l option, so I think the proposed method is similiar to "cp -lr" on Linux systems.

This ticket hasn't seen action in a year, but I wanted to chime in and +1 the feature.
Having a convenience function to recursively create hard links based on a source directory is a rare need, but a need, nonetheless. I think FileUtils is a fine place for it when compared to the other choices of where to place it in Ruby core.

Accepted, but I am against the name ln_r
because it behaves differently from ln -r
(relative).

After discussion at the developer meeting, cp_lr may be an consensus.
