@garritfra Totally. One major split is with the GNU tools and the BSD ones, where Apple wouldn't touch the former if their lives depended on it. The tools are of course easy to install yourself on Mac, but portability is still a concern as soon as someone else is going to use it. Almost like there should be a "jQuery for shell scripts", normalizing commands between environments. Perhaps there is and some reply guy will be happy to tell me about it. If so, feel free to do so :)
