Find#find automatically follows symbolic links to real files but
not to directories. How can I perform a recursive traversal of
a directory tree including sym.links to directories?
Thanks,

The Unix command-line find has a ‘-follow’ option.
Under Ruby you could try something nefarious like:
require ‘find’
dirs = [“.”]
dirs.each do |dir|
Find.find(dir) do |f|
dirs.push File.readlink(f) if FileTest.symlink?(f) and FileTest.directory?(f)
puts f
end
end
I’m never particularly happy about modifying an array whilst iterating
through it 
The above code almost certanily won’t work for relative symbolic links, e.g.
e.g. foo/bar/src → …/baz/src
It would be nice if Find had a ‘follow’ method, like ‘prune’, which did the
Right Thing[TM]
