How can I delete the current file in vim?

Question

How can I delete from the disk the current open file from within vim? Would be nice to also close the buffer.

I see you can use NERDTree for that, but I don\'t use this

You can do it with two steps:

1. save as a new file

   :w newfilename

2. delete the old file

   ! rm oldfilename
