Re: -ls0

Hi James,

Thanks for the quick reply.

    Why not just use \0 in the format specification?

Of course.  That was the basic idea of what I was trying.

    Alternatively, emit the symlinks into a separate file with -fprintf.

Yes, a viable and more reliable alternative.  Only downside is that it's
a bit more annoying to have two files hanging around.

    Unprintable/unusual characters are escaped only when the output is
    going to a tty.  See the info node "Unusual Characters in File Names"

I saw that, but ... well, doesn't matter now.  Yes, ok, works.

So, how about giving this as an example in the manual?  Something like
(under -printf):

--- f/ORIG/find.texi    2011-12-29 11:23:41.000000000 -0800
+++ f/find.texi 2011-12-31 11:15:18.000000000 -0800

 you want a newline at the end of the string, add a @samp{\n}.
+
+As an example, an approximate equivalent of @samp{-ls} with
+null-terminated filenames can be achieved with this @code{-printf}
+format:
+
address@hidden
+find -printf "%i %4k %M %3n %-8u %-8g %8s %T+ %p\n->%l\0" | cat
address@hidden example

+A practical reason for doing this would be to get literal filenames in
+the output, instead of @samp{-ls}'s backslash-escaped names.  (This is
+also why we pipe through @code{cat}; @pxref{Unusual Characters in File
+Names}).  This format also outputs a uniform timestamp format.
+
+As for symlinks, the format above outputs the symlink target on a
+second line, following @samp{\n->}.  There is nothing following the
+arrow for non-symlinks.  Another approach, for complete consistency,
+would be to @code{-fprintf} the symlinks into a separate file, so they too
+can be null-terminated.
