If you really want this feature, yet cannot afford the
access-files-twice approach, consider processing du -a0 output
so as to transform file names like these:
a/b/c/file
a/b/c
a/b
a
into this:
a/b/c/file
a/b/c/
a/b/
a/
i.e., in iterating through names, when dirname($prev) == $name,
append a "/" to $name.
However, that would not annotate the name of an empty directory.
$ mkdir -p a/b/c/d a/empty
$ du -a0 a|perl -MFile::Basename -0ne 'chomp; $s=/^\d+\t(.*)/ &&
(defined $prev ? dirname ($prev) eq $1 : 0) ? "/" : "";
print "$_$s\n"; $prev = $1'
0 a/empty
0 a/b/c/d
0 a/b/c/
0 a/b/
0 a/
