rsync

drush aliases allow you to run a drush commands on your local server but actually execute the command on a remote server.

One can create aliases in a folder that drush recognizes, mostly inside the .drush folder for Linux Based Systems. For a mysite example, we can create a file called as mysite.aliases.drushrc.php inside the .drush folder (Or any folder which Drush goes through before executing). All aliases in a site can also be combined in a single file called as aliases.drushrc.php

Example data that can be added to mysite.aliases.drushrc.php

To transfer file to a different port using RSync:
<i> rsync -avz --progress --rsh='ssh -p1516' source user@host:destDir/ </i>

rsync -avz -e "ssh -p $portNumber" user@remoteip:/path/to/files/ /local/path/

The source can be a file or a directory to be copied to the destination directory
