Sometimes it is cheaper and simpler to just hard code setting the group, owner, permissions unconditionally than to fetch and compare.

You might want to look into sticky group and sticky id directories, see man chmod.

Even copying files might be cheaper than comparing the innards, especially moving or hard linking files.

Trimming: should the directories only contail these files. Nicer architectures store the working and temp data files for runtime in a different subtree from the delivered code, so this is a simple question. I often teach that what you buy should be segregated from what you download and use as is should be segregated from what you write should be segregated from the data it manipulates, for each user where applicable. Then you can clean any subtree for an upgrade of that part of the system. Odd files can destabilize the product and invalidate the testing.

strmode

STRMODE(3)						   BSD Library Functions Manual 						STRMODE(3)

NAME

     strmode -- convert inode status information into a symbolic string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     void
     strmode(mode_t mode, char *bp);

DESCRIPTION

     The strmode() function converts a file mode (the type and permission information associated with an inode, see stat(2)) into a symbolic
     string which is stored in the location referenced by bp.  This stored string is eleven characters in length plus a trailing NUL.

     The first character is the inode type, and will be one of the following:

	   -	 regular file
	   b	 block special
	   c	 character special
	   d	 directory
	   l	 symbolic link
	   p	 fifo
	   s	 socket
	   w	 whiteout
	   ?	 unknown inode type

     The next nine characters encode three sets of permissions, in three characters each.  The first three characters are the permissions for the
     owner of the file, the second three for the group the file belongs to, and the third for the ``other'', or default, set of users.

     Permission checking is done as specifically as possible.  If read permission is denied to the owner of a file in the first set of permis-
     sions, the owner of the file will not be able to read the file.  This is true even if the owner is in the file's group and the group permis-
     sions allow reading or the ``other'' permissions allow reading.

     If the first character of the three character set is an ``r'', the file is readable for that set of users; if a dash ``-'', it is not read-
     able.

     If the second character of the three character set is a ``w'', the file is writable for that set of users; if a dash ``-'', it is not
     writable.

     The third character is the first of the following characters that apply:

     S	   If the character is part of the owner permissions and the file is not executable or the directory is not searchable by the owner, and
	   the set-user-id bit is set.

     S	   If the character is part of the group permissions and the file is not executable or the directory is not searchable by the group, and
	   the set-group-id bit is set.

     T	   If the character is part of the other permissions and the file is not executable or the directory is not searchable by others, and the
	   ``sticky'' (S_ISVTX) bit is set.

     s	   If the character is part of the owner permissions and the file is executable or the directory searchable by the owner, and the set-
	   user-id bit is set.

     s	   If the character is part of the group permissions and the file is executable or the directory searchable by the group, and the set-
	   group-id bit is set.

     t	   If the character is part of the other permissions and the file is executable or the directory searchable by others, and the ``sticky''
	   (S_ISVTX) bit is set.

     x	   The file is executable or the directory is searchable.

     -	   None of the above apply.

     The last character will always be a space.
