Answer 1

::change the values bellow with a relevant ones.
set "file=C:\some.file"
set "last_lines=2"


for /f %%a in ('findstr /R /N "^" "%file%" ^| find /C ":"') do @set lines=%%a
set /a m=lines-last_line
more +%m% "%file%"

Directly from the command line:

C:\>set "file=C:\some.file"
C:\>set "last_lines=5"
C:\>(for /f %a in ('findstr /R /N "^" "%file%" ^| find /C ":"') do @set lines=%a)&@set /a m=lines-last_lines&call more +%m% "%file%"
