> If you have a problem that involves "run a command with a list of parameters but not if the list is empty" and you don't immediately think of `xargs -r`, then consider that it's because you don't understand the tools, not because the tools are bad.

find has -exec, xargs isn't necessary.

`-exec` would run the command for each file separately, which isn't what the original problem wanted, and I didn't want to assume that it would be equivalent.

It runs them separately if you end the exec with ";", it appends as many as possible to the same command if you end it with "+"
