Trailing Slash in rsync command

Just making a quick reference to the rysnc manual in order to synchronize directories

The command used to copy folders is as follows:

rsync -avz foo:src/bar /data/tmp

This command copies the directory bar in /data/tmp .. 

meaning at the end of this command, you will have /data/tmp/bar folder

If you just want to sync the folders then use the trailing slash like this

rsync -avz foo:src/bar/ /data/tmp 

Now only the contents of bar will be copied into /data/tmp folder;

 you will not find a folder called bar in /data/tmp
