More detailed description of your change,

nit: for the commands that have output, losing the > means that it's not as clear what is the command and what is the output. (The new line might be clear enough)

Seems like an ok enough tradeoff to ensure that folks don't overwrite the files though.

And given this was already the case for copy pasting the whole thing, I'd say this is a net positive, so I think it is ok as proposed in the PR.
