BAT file to read and copy bottom 16 lines from a text file to another one?

Question

I need to copy the bottom 16 lines from a text file to another text file. I need to do this procedure for all clients. At the client\'s location the text file will be common

Answer 1

I adapted this useful code to append together 51 files and retain the 12 line header of the first file as follows:

REM Append 51 files and retain 12 line header of first file
REM  ------------------------------------------------------

REM Set number of files to combine    
set Nmbrfls=51   

REM copy the first file with the header 
copy file_1.txt combined.txt

REM Loop through the other 50 files (start at #2) appending to the combined
REM file using a temporary file to capture all but the the 12 header lines
REM than append the temporary file to the combined on each loop

for /l %%i in (2,1,%Nmbrfls%) do (
more /e +13 file_%%i.txt > temp.txt
copy /b combined.txt + temp.txt combined.txt
del temp.txt
)
