$ for i in w x y; do sleep 4; touch $i; done
$ find ? -newer x
y
$ find ? ! -newer x
w
x
OK, so how does one find just
x
y
?
No easy way, as you have a unsymmetrical -newer without a matching -older.
One must resort to big hassles to work around your unsymmetrical
offering of commands.
You might say "no big deal, just do
$ find ? -newer w
x
y
Case closed."
Well, that _just assumes_ we know about file w. But if we knew about all
the files, we wouldn't be using the find(1) command in the first place.
I mean we can always say "up to and including" in English, but not
find(1).
So do something please about the situation. Perhaps implement a -older,
or something else.
