...there's a neat little thing called xterm (and kin), a brand-new
invention as of only a few decades ago. Gives you nice little bash
prompts, as many of them as you want, in a pretty little graphical
window.

If you can't remember "rsync -avz source destination", you have much
bigger problems. ;->

Well, that depends on what you're copying, doesn't it? I'm usually
copying an entire directory tree, or an entire filesystem.

If you can't figure out * and ?, which is generally all you need (and
should be familiar at least to old fogies from DOS, which borrowed them
and slightly screwed them up), you have _much_ bigger problems.

Then, you put each of them in a series of consecutive lines, store that
as a file, and run it as a script. Right? I mean, pretty much like DOS
batch files. A to-do list for the shell.

Yes, having canned software make decisions for you rather than needing
to think is indeed easier.

That would be the exclude options, which personally I don't bother to
remember and look up when I need them.

Absolutely, please do feel welcome to proceed, if you feel you have
things to get off your chest.
