Suggestion to use `date +%s` instead of '.bak'

[joelfranusic-okta]

In your bak function, you rename a file to ".bak", I humbly propose that you use the current time_t instead, since this gives you a "stack" instead.

It's pretty easy to get time_t on a modern unix system:

echo `date +%s`

I don't disagree but not a problem I run into often enough to warrant it. :) I aim for solving the 80-90% case, the rest I'm happy to do manually.
