Where are we up to on the copyright assignment, now?

BTW: In the meantime, du(1) has learned the --threshold option
which can be used to filter by file size or by the apparent file
size (available in coreutils >= v8.21).
Git commit:
Texinfo page:

This can also be used to find "big" directories.
Yet, a new option in find may be good in combination with
other query options.

I'm 100% busy today, I'll try to act tomorrow, see if I can find the documents.

Alas, no - this web page is not the right place for copyright disclaimers.  But I will send you directions via email to the correct web page (assuming you reside in the US) or directions for starting a snail mail exchange (if you reside elsewhere).

Dear FSF,

I do not understand  your request to assign copyright to you. If I do so, I lose the right to sue any possible violations of the GPL.

If I don't you'll still be able to start the courtcase because you own some of the copyrights.

Anyway, this is not the place to fight over such issues.

I hereby assign the copyrights of the submitted code over to the FSF.

  Roger Wolff.

Is it OK like this?

Er... any chance we could have both, please? I can see good uses for both "-space <size>" and "-sparse" predicates.

I think it is likely to be more useful to be able to select files on their sparseness (rather than the total blocks occupied).  However, I'm inclined to ask the list members what they'd find useful.  If there is a consensus option, we can go with that.  

Any thoughts, folks?

It is useful to search for files that take a lot of disk space. I happen to have a lot of files that are 1Gbyte large, but occupy only their inode: they are completely zero.

I have a cronjob that tries to compress such files. however, compressing those files that only contain zeroes takes a lot of CPU time, and only increases the disk usage.

The attached patch implements the -space predicate that checks (like -size) the size-on-disk instead of the file length.

I'm a technical guy, so I built the patch, but haven't update the docs. Just drop me a note if you are going to incorporate this and want me to write the documentation.

The patch shortens the sourcecode by about 30 lines of code.
