Remove any numbers at the front of a file name or remove the first two numbers for Mac I have a thousand files that are named like this...

01 heartbeat a.wav
02 heartbeat b.wav
03 heartbeat c.wav

I'm looking for a terminal command that will remove the numbers at the front of the name.
And when I use the code do I start with

"cd_" 
drop the folder in terminal
enter
"ls"
enter
Copy and paste the command?

Thank you!!
This answer recommends you install rename via brew.
