Yes, and such filenames wouldn't be understood anyway, even if the next program in the pipeline (ls, wc, du) assumed \n-separated lines. All I'm saying is that if you have to choose, choose \0. Otherwise, you'd have completely non-doable commands (besides invoking GCC). Let's say you have a bunch of files, some of which contain \n in their names. So you use find to generate a list. How do you deal with those problem files? You can use -print0, but then if wc wants \n-separated lines, you'd try to use tr and find that it just ambiguates the different kinds of \n - charset for filenames and filename separators. Luckily, none of du, ls or wc use -0, so these tools could just adopt xargs's way of doing it: user chooses with -0 or not- -0. Personally, I don't like the idea of wanting backslash-escaped filenames on bit. - -- [I can't guarantee the integrity of my mail; I suspect my employer of mail tampering (adding disclaimers without my authorization).
