Excellent tool for partitioning filetrees. Obvioulsy designed with rsync in mind, but can be used for any function or util that requires you to partition a filetree into equal chunks so you can do something with those chunks. By aggregate size of referenced file, by number of files, etc. Similar to the kdirstat-cache-writer that comes with the beautiful kdirstat, but fpart has some added benefits, chiefly the live option which partitions as it goes, as opposed to kdirstat util which has to complete the recursion before you can use the output. surprisingly, even tho kdirstat is in Perl and this is compiled C, they're comparably fast, but fpart is more flexible. Well-documented, well-designed, easily compiled, good help. Beautiful little util.
Thanks for Fpart, it's the best!
