Oh, I certainly use tar more than zip. My downloads directory has 67 tar files and 15 zip files. Bear in mind though that the hypothesis is not specific to Unix development. The examples are: cp file1.txt file2.txt file3.txt destination/ mv file1.txt file2.txt file3.txt destination/ The equivalent in MS Windows command shell is: copy file1.txt file2.txt file3.txt destination\ move file1.txt file2.txt file3.txt destination\ The hypothesis makes the prediction that Windows command-line users (which is a subset of all Windows users) will have similar problems with zip/7zip/rar's "inverted" command-line parameters. Similarly, the hypothesis predicts that people who use the command-line to work regularly with .jar, .odf, and other zip-based file formats will also have problem with the ordering. I have not heard of such problems, but I am not knowledgeable about those areas of development.
