How to install rsync on TI Sitara Starter Kit?


I see a post on-line running rsync on raspberrypi:

rsync -rl --delete-after --safe-links pi@192.168.1.PI:/{lib,usr} $HOME/raspberrypi/rootfs

I find that my Sitara Starter Kit has not installed such a command yet. Sitara SK is similar 
to BeagleBone Black. Could you tell me how to install it, with what procedure to install it.

I am still new to embedded Linux.
