[linux]在使用rsync时需要注意的小细节

Posted 2022-10-20 senwren

很简单：前一个目录末尾是目录的话，最后是否带/是有区别的。

具体看测试：

 1 # usr @ the-pc in ~/cptest02 [2:28:02] 
 2 $ ll 
 3 总用量 0
 4 
 5 # usr @ the-pc in ~/cptest02 [2:28:03] 
 6 $ ll ../cptest01/ 
 7 总用量 4
 8 -rw-rw-r-- 1 usr usr    0 10月 11 02:23 11111file
 9 drwxrwxr-x 2 usr usr 4096 10月 11 02:23 pppp
10 
11 # usr @ the-pc in ~/cptest02 [2:28:14] 
12 $ rsync -av ../cptest01/ ./
