How to change your implementations if you have to move a lot of small-size text files in the same directory by one go

<t>oh, by the way, be careful about relative vs. absolute paths when using tar. If using absolute paths, then when unpacking the archive you might end up writing them back to the original location. If chaining the pack & unpack together with a pipe, resulting in both being in play concurrently, ...
