And yet, after 40+ years, the (AFAIK) best this evolution has produced is http://en.wikipedia.org/wiki/Xargs, which, if I follow http://stackoverflow.com/questions/896808/find-exec-cmd-vs-x..., still lacks an all-important -- argument. Or maybe we should follow http://stackoverflow.com/questions/7039130/bash-iterate-over...?
I think the Unix world needs something that stands to the combination of find and xargs as ack (http://betterthangrep.com/) stands to grep.
Most of them (if you are referring to command-line utilities) are open-source. I see this variety of implementations as a good thing - evolution relies on diversity and the openness makes it possible for software to "reproduce sexually", making evolution easier.
