I have observed that there are often subtle and often annoying differences between the default versions of certain command line tools like paste and sed on modern distributions of Linux versus OSX. This leads to answersanswers that do not work on OS X even though they will work on almost any Linux distribution.
So I wonder, is there a standard way to get the full set of OS X versions of the standard Unix tools on modern Linux distributions so we can test solutions for correct functionaity on OSX, without having a copy?
