Feels dangerous to run. What happens if the file already exists and has something important in it?

touch -a is probably better

The other command could just be printf '' >> file to not overwrite it. Or even simpler >>file and then interrupt

or :>>file then you don't need to interrupt

that's awesome, did not know about that handy operator!

Yeah!

it's basically a noop, I use it as a placeholder when I'm writing a script, since bash doesn't accept code blocks with no commands
