UNISON file synchronizer can be install through yum by the below command

yum install unison -y

Note: Make sure that you have EPEL repository installed/enabled on the server


apt-get install unison

unison -batch /path/to/local/directory ssh://remote.server.com///path/to/remote/directory

Note: Make sure that the both the servers are configured with Key Based SSH Authentication to avoid password prompts during sync..
