What's this?

ln(src, dest, force: nil, noop: nil, verbose: nil) public

In the first form, creates a hard link link which points to target. If link already exists, raises Errno::EEXIST. But if the :force option is set, overwrites link.

Bundler::FileUtils.ln 'gcc', 'cc', verbose: true
Bundler::FileUtils.ln '/usr/bin/emacs21', '/usr/bin/emacs'

In the second form, creates a link dir/target pointing to target. In the third form, creates several hard links in the directory dir, pointing to each item in targets. If dir is not a directory, raises Errno::ENOTDIR.

Bundler::FileUtils.cd '/sbin'
Bundler::FileUtils.ln %w(cp mv mkdir), '/bin'   # Now /sbin/cp and /bin/cp are linked.
