Whatever you are doing, you should take into account one simple
fact: if you write data in one program to later on read it in
the next one, *you* have (some) control over what and where
remains on that disk. If you "pipe" data from one program into
another using the shell, *the system* writes pieces of "pipe"
on the disk, and you have little or no control over what and
where will be left on that disk.
