For example, to copy a directory named “folder” from /home/user/ to another location, you would run the following command: rsync -av /home/user/folder/ /destination/folder/ The “-av” flag stands for “archive mode”, “verbose output”, respectively. It ensures that rsync copies all contents of the specified folder, while displaying detailed logging information. Once the command is run, rsync will start copying the folder and its contents. When it is done, it will display a summary of the number of files and bytes transferred.
