シェルスクリプトdiffer-r

このシェルスクリプトは両方のディレクトリの再帰比較を実行できますが、特定のファイル名またはファイルタイプパターンと一致するファイル（その場所にある）のみを比較します。

#!/bin/bash

greenvid="\0033[32m"
resetvid="\0033[0m"

if [ $# -ne 3 ]
then
 echo "Usage: compare files in two directories including subdirectories"
 echo "         $0 <source-dir> <target-dir> <pattern>"
 echo "Example: $0  subdir-1     subdir-2     \"*.txt\""
 exit
fi

cmd='for pathname do
        greenvid="\0033[32m"
        resetvid="\0033[0m"
        echo -e "${greenvid}diff \"$pathname\" \"${pathname/'\"$1\"'/'\"$2\"'}\"${resetvid}"
        diff "$pathname" "${pathname/'\"$1\"'/'\"$2\"'}"
    done'
#echo "$cmd"

find "$1" -type f -name "$3" -exec bash -c "$cmd" bash {} +

デモ

文書：

$ 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

使用法:

$ ./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"

ランニングdiffer-r:

実行されたdiffコマンドラインは緑色のテキストで印刷され、一致するものがない場合、出力はデフォルトのテキスト（下のスクリーンショットの黒い背景に白いテキスト）として印刷されます。

$ ./differ-r 1 2 "*.doc"
diff "1/two.doc" "2/two.doc"
diff "1/sub/only-one.doc" "2/sub/only-one.doc"
diff: 2/sub/only-one.doc: No such file or directory
diff "1/sub/hello.doc" "2/sub/hello.doc"

rsyncフィルタを含む

違いを説明する出力を取得する必要がなく、どのファイルが異なるか欠落しているかを知っている場合（コピーrsyncする場合）、次のコマンドラインを使用できます。

rsync --filter="+ <pattern>" --filter="+ */" --filter="- *"--filter="- */"  -avcn <source directory>/ <target directory>

デモ

$ 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)

コメントアウトされた行やディレクトリなしできれいな出力が必要な場合は、grep次のように出力できます。

$ pattern="*.doc"; rsync --filter="+ $pattern" --filter="+ */" --filter="- *"  -avcn 1/ 2 | grep "${pattern/\*/.\*}"
sub/hello.doc
sub/only-one.doc

シェルスクリプトrsync-diff

この行はシェルスクリプトの重要なコマンドですrsync-diff。

#!/bin/bash

LANG=C

if [ $# -ne 3 ]
then
 echo "Usage: compare files in two directories including subdirectories"
 echo "         $0 <source-dir> <target-dir> <pattern>"
 echo "Example: $0  subdir-1     subdir-2     \"*.txt\""
 exit
fi

pattern="$3"; rsync --filter="+ $pattern" --filter="+ */" --filter="- *" \
 -avcn "$1"/ "$2" | grep "${pattern//\*/.\*}" | grep -v \
  -e '/$' \
  -e '^sending incremental file list$' \
  -e '^sent.*received.*sec$' \
  -e '^total size is.*speedup.*(DRY RUN)$'
