Seems like deja vu. Compare the file lists of the two directories, and the file content, using something like this:
Code:
diff -U0 <(
  cd head1
  find * -type f | sort | xargs -r cksum ) <(
  cd head2
  find * -type f | sort | xargs -r cksum ) | while read  diff_ind  cksum  sz  path
do
 case "$diff_ind" in
 (-)
  echo "Deleted file '$path'."
  ;;
 (+)
  echo "New file '$path':"
  cat head2/$path
  ;;
 (*)
  echo "Changed file '$path':"
  sdiff head1/$path head2/$path
  ;;
 esac
done

For stricter delete/new checking, use 'comm' not 'diff -U0' but no '| xargs -r cksum' until later, when you know both are present (no tab prefix is delete, one tab is new, two tabs is both). You can report new/delete on stderr and pipe others to stdout to cksum to another while read to compare cksums before running an sdiff.

systemd-path

SYSTEMD-PATH(1)                                                    systemd-path                                                    SYSTEMD-PATH(1)

NAME

       systemd-path - List and query system and user paths

SYNOPSIS

       systemd-path [OPTIONS...] [NAME...]

DESCRIPTION

       systemd-path may be used to query system and user paths. The tool makes many of the paths described in file-hierarchy(7) available for
       querying.

       When invoked without arguments, a list of known paths and their current values is shown. When at least one argument is passed, the path
       with this name is queried and its value shown. The variables whose name begins with "search-" do not refer to individual paths, but instead
       to a list of colon-separated search paths, in their order of precedence.

OPTIONS

       The following options are understood:

       --suffix=
           The printed paths are suffixed by the specified string.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
