使用rsync 的 --delete参数删除目标目录比源目录多余的文件

root@v01 ~]# mkdir dir01 dir02
[root@v01 ~]# ls
anaconda-ks.cfg  dir02   framework    install.log.syslog  mobile
dir01            ecshop  install.log  localsvn            online

[root@v01 ~]# touch dir02/{file1A.txt,fileA2.txt,fileA3.txt,fileB1.txt,fileB2.txt,fileB3.txt}
[root@v01 ~]# touch dir01/{file1A.txt,fileA2.txt,fileA3.txt}

[root@v01 ~]# ls dir01
file1A.txt  fileA2.txt  fileA3.txt
[root@v01 ~]# ls dir02
file1A.txt  fileA2.txt  fileA3.txt  fileB1.txt  fileB2.txt  fileB3.txt
[root@v01 ~]#

将dir01的所有文件同步到dir02内，并保留文件的属主，属组，文件权限等信息

[root@v01 ~]# rsync -avz dir01/* dir02/
sending incremental file list
file1A.txt
fileA2.txt
fileA3.txt

sent 166 bytes  received 69 bytes  470.00 bytes/sec
total size is 0  speedup is 0.00

将dir01的所有文件同步到dirB内，并删除dir02内多余的文件：

[root@v01 ~]# rsync -avz --delete dir01/* dir02/
sending incremental file list

sent 58 bytes  received 12 bytes  140.00 bytes/sec
total size is 0  speedup is 0.00

失败！！！！

[root@v01 ~]# rsync -avz --delete dir01/ dir02/
sending incremental file list
./
deleting fileB3.txt
deleting fileB2.txt
deleting fileB1.txt

sent 71 bytes  received 15 bytes  172.00 bytes/sec
total size is 0  speedup is 0.00

[root@v01 ~]# ls dir02/
file1A.txt  fileA2.txt  fileA3.txt

成功！！！！

[root@v01 ~]# touch dir02/fileB04.txt
[root@v01 ~]# ls dir02
file1A.txt  fileA2.txt  fileA3.txt  fileB04.txt

[root@v01 ~]# rsync -avz --delete dir01/* dir02/*

将dir01目录内的test目录不同步到dir02目录内

[root@v01 dir01]# ls
file1A.txt  fileA2.txt  fileA3.txt
[root@v01 dir01]# mkdir test
[root@v01 dir01]# ls
file1A.txt  fileA2.txt  fileA3.txt  test

[root@v01 dir01]# cd ..
[root@v01 ~]# ls
anaconda-ks.cfg  dir02   framework    install.log.syslog  mobile
dir01            ecshop  install.log  localsvn            online

[root@v01 ~]# rsync -arvz --exclude="test" --delete dir01/ dir02/
sending incremental file list
./
deleting fileB04.txt

[root@v01 ~]# ls dir02/

同步的同时也包含隐藏文件:

[root@v01 dir02]# ls
file1A.txt  fileA2.txt  fileA3.txt
[root@v01 dir02]# mkdir .test
[root@v01 dir02]# ls

将dir01的所有文件除test之外 同步到 dir02，但是在dir02内除了.kk 这个文件不删之外，其他的都删除

[root@v01 ~]# rsync -arvz --exclude="test" --exclude=.kk --delete dir01/ dir02/
