Shell-Skript differ-r
Dieses Shellscript kann einen rekursiven Unterschied zwischen zwei Verzeichnissen ausführen, jedoch nur Dateien (an ihren jeweiligen Stellen) vergleichen, die einem bestimmten Dateinamen oder Dateitypmuster entsprechen.

Demo
Dateien:
$ 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
Verwendungszweck:
$ ./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"

Die ausgeführten diff
Befehlszeilen werden mit grünem Text gedruckt, und die Ausgabe, wenn keine Übereinstimmung vorliegt, wird mit Standardtext gedruckt (weiß auf schwarz im folgenden Screenshot).
$ ./differ-r 1 2 "*.doc"

rsync
mit Filter
Wenn Sie keine Ausgabe erhalten müssen, die den Unterschied beschreibt, nur wissen, welche Dateien unterschiedlich sind oder fehlen (damit rsync
Sie sie kopieren möchten), können Sie die folgende Befehlszeile verwenden.
rsync --filter="+ <pattern>" --filter="+ */" --filter="- *"--filter="- */" -avcn <source directory>/ <target directory>
Demo
$ rsync --filter="+ *.doc" --filter="+ */" --filter="- *" -avcn 1/ 2
sending incremental file list
./
sub/
sub/hello.doc
sub/only-one.doc
sent 276 bytes received 35 bytes 622.00 bytes/sec
total size is 40 speedup is 0.13 (DRY RUN)
sent 360 bytes received 41 bytes 802.00 bytes/sec
total size is 61 speedup is 0.15 (DRY RUN)
olle@bionic64 /media/multimed-2/test/test0/temp $ rsync --filter="+ *.txt" --filter="+ */" --filter="- *" -avcn 1/ 2
sending incremental file list
./
ett.txt
t r e.txt
sub/
sent 184 bytes received 29 bytes 426.00 bytes/sec
total size is 21 speedup is 0.10 (DRY RUN)
Wenn Sie eine saubere Ausgabe ohne Kommentarzeilen und ohne Verzeichnisse wünschen, können Sie grep
die Ausgabe wie folgt ausführen:
$ pattern="*.doc"; rsync --filter="+ $pattern" --filter="+ */" --filter="- *" -avcn 1/ 2 | grep "${pattern/\*/.\*}"
sub/hello.doc
sub/only-one.doc
Shell-Skript rsync-diff
Dieser Einzeiler kann zum Kernbefehl eines Shellskripts gemacht werden rsync-diff
.
