Just look at the output. It's terrible. What you want is a list of
files, and `ls -R` is meant to be human-readable, not piped directly
into another process.

What you're probably looking for is something like "find". Just running
"find" will list absolutely everything it can find from the current
directory onwards. If you don't want things like directories or special
files specifically listed, then do "find -type f" to find only regular
files. If you don't want to use the current directory, use
"find -type f ".

Did you try it without the option flag -R?

Yeah, I know about find. I was wondering why the -R option borked, since
it's recursive (and seem to be the obvious choice).

If didn't; you are using it for something its output is not
designed for.

If you look at the output, you'll see that it is obviously NOT the
correct choice.
