[Linux] when using rsync need to pay attention to small details

It is simple: before the end of the directory is a directory, and finally with whether /there is a difference.

Specific test to see:

. 1 # @ usr The PC- in ~ / cptest02 [ 2 : 28 : 02 ] 
 2  $ LL 
 . 3 the total amount of 0 
. 4  
. 5 # @ usr The PC- in ~ / cptest02 [ 2 : 28 : 03 ] 
 . 6 $ LL ../ cptest01 /
