shred rename behavior

[Nuzhna Pomoshch]

Hi,

I have a number of very long file names (~200 characters). When I use shred on 
them, first of all, it slows shred down a bit doing 200 renames, and second, 
for files on SSDs, I worry that so many write operations will cause the SSDs to 
wear out before they otherwise would.

I wonder if you know any way to perhaps rename a file to all zeros, then rename 
it to a single zero, and then unlink it. I guess I just don't see the gain from 
the extra security in the present method as worth the cost.

Any thoughts? Thank you in advance.
