셸 스크립트 differ-r

이 쉘 스크립트는 두 디렉토리의 재귀 diff를 수행 할 수 있지만 특정 파일 이름 또는 파일 유형 패턴과 일치하는 파일 만 (해당 위치에서) 비교합니다.

#!/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 {} +

데모

파일 :

$ 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

용법:

$ ./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"

달리기 differ-r:

수행 된 diff명령 행은 녹색 텍스트로 인쇄되고 기본 텍스트와 일치하지 않는 경우 출력됩니다 (다음 스크린 샷에서 검은 색은 흰색).

$ ./differ-r 1 2 "*.doc"
diff "1/two.doc" "2/two.doc"
diff "1/sub/only-one.doc" "2/sub/only-one.doc"

rsync 필터 부착

차이를 설명하는 출력을 얻을 필요가없고, 파일이 다르거 나 누락 된 파일 만 알고 있으므로 ( rsync복사하려는 경우) 다음 명령 행을 사용할 수 있습니다.

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

데모

$ 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)

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

./

주석이없고 디렉토리가없는 깨끗한 출력을 원한다면 다음 grep과 같이 출력 할 수 있습니다 .

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

셸 스크립트 rsync-diff

이 하나의 라이너는 쉘 스크립트의 핵심 명령으로 만들 수 있습니다 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$' \
  -e '^total size is.*speedup.*(DRY RUN)$'
