[Question] How to use "copy" in program

I was writing an install program and i want to use "copy" command but how to use it in program?
As i saw that redpulse is and command but rs.setOutput is like redpulse but like command.

you could do shell.run(), but the fs api has a copy() function

fs.copy(sourcePath,newPath)

As usual, the wiki is a great resource. I would suggest looking at the help on the Fs commands. In specific, you can use Fs.copy() to perform this action.

When I write and run that, It says : (my program name) :(line): attempt to perform aritchmetic __div on table and nil
I'm new to Lua so can someone help me?

paths are strings. put ""s around them.
