rsync is a wonderfully useful utility for copying files both locally and between machines. It makes a reasonable effort to copy only files that have changed, which can save a tremendous amount of time in many scenarios. However, I’ve always been a bit daunted by its plethora of command-line options, and would always resort to its man page for every invocation. Thus, it would never stick in my set of tools I would commonly use. After doing some work where rsync really was the only tool for the job, I decided to finally make a little cheatsheet on how to use rsync.
