[Linux]rsync

1. src ディレクトリ内にある a.txt, b.txt を dst ディレクトリに同期させる

   $ ls src
   a.txt  b.txt
   $ ls
   src
   
   $ rsync -auv --delete src/ dst
   sending incremental file list
   created directory dst
   ./
   a.txt
   b.txt
   
   sent 158 bytes  received 53 bytes  422.00 bytes/sec
   total size is 0  speedup is 0.00
   $ ls
   dst  src

2. 差分確認

   $ diff src/ dst/

3. src ディレクトリに c.txt を追加

   $ touch src/c.txt

4. 同期

   $ rsync -auv --delete src/ dst
   sending incremental file list
   ./
   c.txt
   
   sent 133 bytes  received 34 bytes  334.00 bytes/sec
   total size is 0  speedup is 0.00

5. src/a.txt を削除

   $ rm src/a.txt

6. 同期実行

   $ rsync -auv --delete src/ dst
   sending incremental file list
   ./
   deleting a.txt
   
   sent 80 bytes  received 15 bytes  190.00 bytes/sec
