I prefer to do such a
step with "grep ." to return all lines that contain non-whitespace
characters.
Well, . matches spaces and tabs, so to be pedantic, that's not entirely
true. :)
But there's nothing between ^ and $ to catch the . so it works just
fine. Better would be to use a g/re/d with an re of "^$". . .
I totally followed all of that *until* "g/re/d". What is that?
Remember where "grep" comes from?
"g/re/p" -> _g_lobally search for _r_egular _e_xpression and _p_rint
Well, "d" instead of "p" means "delete"; thus, g/re/d
I think I understand, kinda like saying:
grep -v ^$
Right?
(Sorry, sometimes I need it to be perfectly obtuse to be certain I have it.)
