Skrypt powłoki differ-r
Ten skrypt powłoki może wykonywać rekurencyjną różnicę dwóch katalogów, ale tylko porównywać (w odpowiednich miejscach) pliki, które pasują do określonego wzorca nazwy pliku lub typu pliku.

Akta:
$ find -type f
./1/ett.txt
./1/two.doc
./1/t r e.txt
./1/sub/only-one.doc
./1/sub/hello.doc
./1/sub/hejsan.doc
./differ-r2
./differ-r1
./differ-r
./2/ett.txt
./2/two.doc
./2/t r e.txt
./2/sub/hello.doc
./2/sub/hejsan.doc
Stosowanie:
$ ./differ-r
Usage: compare files in two directories including subdirectories
./differ-r <source-dir> <target-dir> <pattern>
Example: ./differ-r subdir-1 subdir-2 "*.txt"
Bieganie differ-r
:
Przeprowadzone diff
linii poleceń są drukowane z zielonym tekstem i wyjścia, gdy nie ma mecz zostanie wydrukowany tekst domyślny (biały na czarnym na poniższym zrzucie ekranu).

rsync
z filtrem
Jeśli nie potrzebujesz żadnych danych wyjściowych opisujących różnicę, wiedz tylko, które pliki są inne lub ich brakuje (aby rsync
je skopiować), możesz użyć następującego wiersza polecenia.
rsync --filter="+ <pattern>" --filter="+ */" --filter="- *"--filter="- */" -avcn <source directory>/ <target directory>
Próbny
$ rsync --filter="+ *.doc" --filter="+ */" --filter="- *" -avcn 1/ 2

Jeśli chcesz uzyskać czysty wynik bez komentowania wierszy i katalogów, możesz uzyskać grep
wynik w ten sposób,
$ pattern="*.doc"; rsync --filter="+ $pattern" --filter="+ */" --filter="- *" -avcn 1/ 2 | grep "${pattern/\*/.\*}"
sub/hello.doc
sub/only-one.doc
Skrypt powłoki rsync-diff
Ten jednowierszowy można przekształcić w podstawowe polecenie powłoki rsync-diff
.
