So, I start with comparing two directories:
[root@135759 ]# rsync -av test1/ test2/ building file list ... done sent 128 bytes received 20 bytes 296.00 bytes/sec total size is 6 speedup is 0.04
They both are in sync Now, let me create a file in test1 and copy it to test2
[root@135759 ]# touch test1/hello4.php [root@135759 ]# scp test1/hello4.php test2/hello4.php
I verify that those are same:
[root@135759 test2]# md5sum test1/hello4.php d41d8cd98f00b204e9800998ecf8427e hello4.php [root@135759 test1]# md5sum test2/hello4.php d41d8cd98f00b204e9800998ecf8427e hello4.php
Thus, running rsync will show me 0 files. Why is the output not right ?
[root@135759 ]# rsync -avn test1/ test2/ building file list ... done hello4.php sent 116 bytes received 24 bytes 280.00 bytes/sec total size is 6 speedup is 0.04
