Note 007 rsync command compares files but does not synchronize them

The rsync command is often used to synchronize files in Linux to ensure the consistency of files in two places. The system will automatically compare to ensure that the files on both sides are the same.

When using this command, another situation is that you want to know which files will be synchronized first, so as to avoid the wrong files from being synchronized when multiple people perform this type of operation.

Hy369 I have struggled with this issue several times, and this time I finally learned from it and decided to record it! !

Only compare the files that need to be synchronized without performing substantial synchronization. You only need to add additional parameters to the rsync command:

rsync -avzn -P 源地址 目标地址
rsync -avz -P --list-only 源地址 目标地址

The additional parameters can be -n or Yes --list-only, the effect is the same, but the latter displays more detailed information.
