PREDICATE is a Lisp expression that can refer to the following variables:

and 2 to attribute of file in second dired buffer.
|
||
|
||
Examples of PREDICATE:
|
||
|
||
(> mtime1 mtime2) - mark newer files
|
||
(not (= size1 size2)) - mark files with different sizes
|
||
(not (string= (nth 8 fa1) (nth 8 fa2))) - mark files with different modes

If COMMAND produces output, it goes to a separate buffer.
|
||
|
||
This feature does not try to redisplay Dired buffers afterward, as
|
||
there's no telling what files COMMAND may have changed.
|
||
Type \\[dired-do-redisplay] to redisplay the marked files.
|
||
|
||
When COMMAND runs, its working directory is the top-level directory of
|

the Dired buffer, so output files usually are created there instead of
|
||
in a subdir.

the list of file names explicitly with the FILE-LIST argument."
