AFAICS `diff` doesn't so much show you what the difference is.
Nor does it <get you from FileA to FileB>.
Rather it 'sells you a ticket' to <get you from FileA to FileB>.
You are not supposed to understand the ticket, which `patch`
[or some other bus company] uses to <get you from FileA to FileB>.
man/info says:-------------------------
`RdL'
Delete the lines in range R from the first file; line L is where
they would have appeared in the second file had they not been
deleted. For example, `5,7d3' means delete lines 5-7 of file 1;
or, if changing file 2 into file 1, append lines 5-7 of file 1
after line 3 of file 2.
------------------------------------
AFAIK the English meaning of 'append' in 'add at the END'
and AFAIK the above author [who's crap is being read by a zillion
victims for decades] means 'add/insert'.
You will correct me it I'm wrong.
The above disasterous description is an example of how folksie
english is no substitute for a more formal mathematical notation.
Apparently `diff` has good algorithms for comparing
<* Hunks:: Groups of differing lines>
in various heuriatic, human-like ways; like ignoring different
white-chars and even with regex fcilities.
But can it be used to:
delete all further huncks in File1 which match File2?
== TIA.
PS. I know it's difficult to write a good `man` for a subtle
utility; but how many decades of successive refinement
do you need to correct it?

Use “diff -u” if you want someone to be able to read the output.

Who said it's supposed to? As the manual states it's purpose it to show

you the diff[erence] between two files. It is not intended to edit
anything. Additionally the patch command can read it's output to
get you from filea to fileb but that's only a fraction of usage cases
for diff.

of append doesn't include "end". The manual's description quoted above
is accurate and precise.

to whine about people's writing you better get yours right.
Provide some detail of what you want to accomplish and someone may be
able to help. Leave out the whining, it just hides your actual question.

I was thinking that it's a SERIOUS problem, if I don't know the
difference between INSERT and APPEND; so when I went on-line,
I shot-off a: `gg1 dictionary+append`

-------------------------------------------
Believe me, I think people who correct foreigner's English grammar
are arse-holes, like people who say/write "having said that" instead of
"but".
But for COMPUTING the difference between INSERT and APPEND is critical.
And what does it matter in this context? Well, the utility is decades old,
and each one of the zillion poor vicitims, has to fall in the same hole,
and LEARN that for a central part of the `diff` docos "append" does
not actually mean APPEND.
Please correct me if I'm wrong.

up over time. I love `mc`, which I've been using since the
days of DOS:nc and it's continually improving, because the

majority definitions indicate simply "add" as did all of the ones
I happened to look at before responding before. Maybe append isn't the
*best* choice of words in the manual but the behavior is clear from
the full context.
The point remains. As others have said, you're free to fix it.
Otherwise deal with it and move on with asking your question
instead of writing a full page complaint about trivial terminology
disagreements like every other flamer on the net. See how effective
that was at getting you an answer to your 2 line question buried at
the end of your rant? 7 responses and no answers. Next time just
ask your question and leave the whining out and you'll probably get
a useful answer instead of return flames. Unless of course all you
really want is a flame war. If so, then by all means pick at every
little nit in all the free software and documentation made available
to you.
