-v：显示传输过程中的详细信息，-v 可以用通过增加 v参数的数量来显示更多详尽的信息。最全面，最详尽的传输信息是 5个v（-vvvvv）。
4-10.6 内容：
通过 rsync -a -v 把文件传输到目标目录。标识 -v 不同数量所增加了哪些信息内容。
操作步骤：
1、新建一个 backups_v 目录用作 -v 参数测试的目标目录。

[root@localhost test]# mkdir backups_v
[root@localhost test]# tree
.
├── backups_v
└── SRC
    ├── demo1.txt
    ├── demo2.txt
    └── demo3.txt

2 directories, 3 files
[root@localhost test]#

2、为了清晰一点，先删除 SRC 目录下的文件，重新创建 1 个文件。

[root@localhost test]# 
[root@localhost test]# ll SRC/
total 8
-rw-rw-rw-. 1 root root  6 Aug  8 22:41 demo1.txt
-rw-rw-rw-. 1 root root 10 Aug  8 22:47 demo2.txt
-rw-rw-rw-. 1 root root  0 Jul 22 22:44 demo3.txt
[root@localhost test]# 
[root@localhost test]# rm -rf SRC/*    ## 删除 SRC目录下的所有文件
[root@localhost test]# 
[root@localhost test]# ll SRC/
total 0
[root@localhost test]# touch SRC/demo1.txt    ## SRC目录下只创建一个 demo1.txt
[root@localhost test]# 
[root@localhost test]# ll SRC/
total 0
-rw-r--r--. 1 root root 0 Aug 10 22:13 demo1.txt
[root@localhost test]#

3、用 rsync -a SRC/demo1.txt 到 backups_v 目录。

## 没有 -v 的加持，传输数据时不会显示信息。
[root@localhost test]# rsync -a SRC/demo1.txt backups_v/
[root@localhost test]# 
[root@localhost test]# tree
.
├── backups_v
│   └── demo1.txt
└── SRC
    └── demo1.txt

2 directories, 2 files
[root@localhost test]#

4、用 rsync -a -v SRC/demo1.txt 到 backups_v 目录，并改名为demo2.txt。

[root@localhost test]# rsync -a -v SRC/demo1.txt backups_v/demo2.txt
## {... 花括号内是 -v 所显示的传输信息
sending incremental file list    
demo1.txt

sent 91 bytes  received 35 bytes  252.00 bytes/sec

 ##...}   
[root@localhost test]# 
[root@localhost test]# tree
.
├── backups_v
│   ├── demo1.txt
│   └── demo2.txt    ## 生成 demo2.txt
└── SRC
    └── demo1.txt

2 directories, 3 files
[root@localhost test]#

5、用 rsync -a -vv SRC/demo1.txt 到 backups_v 目录，并改名为demo3.txt。

[root@localhost test]# 
[root@localhost test]# rsync -a -vv SRC/demo1.txt backups_v/demo3.txt
sending incremental file list

##{...花括号内是比 -v 多出的内容
delta-transmission disabled for local transfer or --whole-file
##...}

demo3.txt is uptodate

##{...花括号内是比 -v 多出的内容
total: matches=0  hash_hits=0  false_alarms=0 data=0
##...}

sent 91 bytes  received 102 bytes  386.00 bytes/sec

│   ├── demo2.txt
│   └── demo3.txt    ## 生成 demo3.txt
└── SRC
    └── demo1.txt

2 directories, 4 files
[root@localhost test]#

6、用 rsync -a -vvv SRC/demo1.txt 到 backups_v 目录，并改名为demo4.txt。

[root@localhost test]# 
[root@localhost test]# rsync -a -vvv SRC/demo1.txt backups_v/demo4.txt
sending incremental file list

## {... 花括号内是比 -vv 多出的内容

7、用 rsync -a -vvvv SRC/demo1.txt 到 backups_v 目录，并改名为demo5.txt。

[root@localhost test]# rsync -a -vvvv SRC/demo1.txt backups_v/demo5.txt
