The “rsync” is a powerful command under the Linux environment. The rsync stands for Remote Sync. Normally rsync is used to transfer file from one server(source) to another server(destination). rsync has a lot of switches or option for managing the command much usefully. Here I am explaining the switches of rsync command with examples. Rsync will actually look and see what in the file has changed and upload only the part of the file that has changed. Unlike ftp and other transfer solutions rsync doesn’t simply re-upload the entire file.
