ln(old, new, options = {})

Creates a hard link new which points to old. If new already exists and it is a directory, creates a link new/old. If new already exists and it is not a directory, raises Errno::EEXIST. But if :force option is set, overwrite new.

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

ln(list, destdir, options = {})

Creates several hard links in a directory, with each one pointing to the item in list. If destdir is not a directory, raises Errno::ENOTDIR.

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