  action :delete
  only_if ???
end

Answer 1

The selected answer will not work on Windows or systems where Bash is the default interpreter. You should use a cross-platform Ruby solution (and faster, since there is no process there):

directory '/var/www/html' do
  action :delete
  not_if { File.symlink?('/var/www/html') }
end

Answer 2

What about:

directory "/var/www/html/" do
    action :delete
    not_if "test -L /var/www/html/"
end

test -L $filereturns 0 (true) if it $fileis a symbolic link.
