Hi, No offense, but what's the benefit of your tool compared to `find . -type f -maxdepth 1 | sort -R | head -n1` command line ? The reservoir-sampling algorithm provide some benefits here ? Regards, -- rodrigo

No offense taken. The reservoir-sampling algorithm will provide benefit for big directories, as it doesn't require sorting input data. For most cases find+sort will do just fine though. I've created this port mainly for myself, so I can easily install this tool on my system. If you don't find this tool useful, I don't mind not including it is ports. I can always fallback to portshaker.
Comment 3 Rodrigo Osorio 2019-08-08 13:37:45 UTC
At this points just two remarks: The algorithm used (reservoir-sampling) should be notified in the package description. And you should add a few words about the benefits of this solution in the long description aka pkg-descr.

A commit references this bug: Author: rodrigo Date: Sun Aug 18 10:34:08 UTC 2019 New revision: 509198 URL: https://svnweb.freebsd.org/changeset/ports/509198 Log: Add new port sysutils/frand frand is a command line tool who returns a random file from a given directory using the reservoir sampling algorithm. With reservoir sampling algorithm, directory contents doesn't need to be read in memory then sorted and so will perform much better than find+sort for directories with a large amount of files.
