This is a completely different problem—

findstr /beivg:_abandoned.txt _to_learn.txt>temp.txt

The function of the above code is to find lines in _to_learn.txt that are not contained in _abandoned.txt.

Testing with _abandoned.txt:

ee
ff
gg
hh


and _learned.txt:

ff
gg
hh
ee

the result always leaves the last line

ee


But if you add a carriage return to the last line of _learned.txt, that is:

ff
gg
hh
ee


then you can get the completely correct result, namely an empty text file _temp.txt.

It does the same thing as typing a carriage return.
