What bugged me more was the snippets designed to show how hard it is to write shell scripts. It looked like the author just didn't know enough about their tools:

>How to touch all files in foo (and its subfolders)?

    find foo -print0 | xargs -0 touch
    find foo -exec touch {} \;

I agree with the other commenters who think it's fine to write whatever you like on your own blog, I just feel that it went from interesting historical warts to bagging on legacy systems because they're complicated.

If we take UNIX to mean the POSIX standard, it doesn't work because -print0 is not in POSIX, and neither is -0 for xargs.
