[linux]在使用rsync时需要注意的小细节

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：

# usr @ the-pc in ~/cptest02 [2:28:02]
$ ll
总用量 0

# usr @ the-pc in ~/cptest02 [2:28:03]
$ ll ../cptest01/
总用量 4
-rw-rw-r-- 1 usr usr    0 10月 11 02:23 11111file
drwxrwxr-x 2 usr usr 4096 10月 11 02:23 pppp

# usr @ the-pc in ~/cptest02 [2:28:14]
$ rsync -av ../cptest01/ ./
sending incremental file list
./
11111file
pppp/
pppp/adadasd.file

sent 187 bytes  received 57 bytes  488.00 bytes/sec

# usr @ the-pc in ~/cptest02 [2:28:33]

# usr @ the-pc in ~/cptest02 [2:28:56]
$

（shell是zsh，主题是ys。）
