File's depth in the directory tree (depth below a file named on the
command line, not depth below the root directory). Files named on the
command line have a depth of 0. Subdirectories immediately below them
have a depth of 1, and so on.
%D
The device number on which the file exists (the st_dev field of
struct stat), in decimal.
%F
Type of the filesystem the file is on; this value can be used for
-fstype (see Directories).
%l
Object of symbolic link (empty string if file is not a symbolic link).
%i
File's inode number (in decimal).
%n
Number of hard links to file.
%y
Type of the file as used with -type. If the file is a symbolic
link, l will be printed.
%Y
Type of the file as used with -type. If the file is a symbolic
link, it is dereferenced. If the file is a broken symbolic link,
N is printed.
