rsync常用选项

rsync常用选项

同步目录并修改名字

[root@wsl-001 grep]# ln -s /root/a.txt /root/grep/a.txt
[root@wsl-001 grep]# ls -l
总用量 12
lrwxrwxrwx  1 root root  11 3月  25 21:51 a.txt -> /root/a.txt
-rw-r--r--. 1 root root 511 1月  24 16:53 inittab
-rw-r--r--. 1 root root 922 1月  24 22:38 passwd
-rw-r--r--. 1 root root 922 1月  24 22:25 passwd1
[root@wsl-001 grep]# rsync -av /root/grep/ /tmp/grep_test/
sending incremental file list
./
a.txt -> /root/a.txt

sent 108 bytes  received 18 bytes  252.00 bytes/sec
total size is 2366  speedup is 18.78
[root@wsl-001 grep]# ls -l /tmp/grep_test/
总用量 12
lrwxrwxrwx 1 root root  11 3月  25 21:51 a.txt -> /root/a.txt

-rw-r--r-- 1 root root 922 1月  24 22:25 passwd1

运用L选项，拷贝软连接的源文件

[root@wsl-001 grep]# ls -l /tmp/grep_test/
总用量 12
lrwxrwxrwx 1 root root  11 3月  25 21:51 a.txt -> /root/a.txt
-rw-r--r-- 1 root root 511 1月  24 16:53 inittab
-rw-r--r-- 1 root root 922 1月  24 22:38 passwd
-rw-r--r-- 1 root root 922 1月  24 22:25 passwd1
[root@wsl-001 grep]# rsync -avL /root/grep/ /tmp/grep_test/
sending incremental file list
a.txt

运用--delete对目标文件进行同步删除

[root@wsl-001 grep]# ls /root/grep/
a.txt  inittab  passwd  passwd1
[root@wsl-001 grep]# ls /tmp/grep_test/
a.txt  inittab  passwd  passwd1
[root@wsl-001 grep]# touch /tmp/grep_test/111
[root@wsl-001 grep]# rsync -avL --delete  /root/grep/ /tmp/grep_test/
sending incremental file list
./
deleting 111

运用P选项显示传输速度

[root@wsl-001 grep]# rsync -avP  /root/grep/ /tmp/grep_test/
sending incremental file list
created directory /tmp/grep_test
./
a.txt -> /root/a.txt
inittab
