You can apply "split" to the output of "tail"j to generate files of with the
same number of lines, that you would process with the program that extracts
the intereresting data from them:

NAME
split - split a file into pieces

SYNOPSIS
split [OPTION]... [INPUT [PREFIX]]

DESCRIPTION
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default
size is 1000 lines, and default PREFIX is `x'. With no INPUT, or when INPUT
is -, read standard input.

Mandatory arguments to long options are mandatory for short options
too.

-a, --suffix-length=N
use suffixes of length N (default 2)

-b, --bytes=SIZE
put SIZE bytes per output file

-C, --line-bytes=SIZE
put at most SIZE bytes of lines per output file

-d, --numeric-suffixes
use numeric suffixes instead of alphabetic

-l, --lines=NUMBER
put NUMBER lines per output file

--verbose
print a diagnostic just before each output file is opened

--help display this help and exit

--version
output version information and exit

SIZE may have a multiplier suffix: b 512, kB 1000, K 1024, MB
1000*1000, M 1024*1024, GB 1000*1000*1000, G 1024*1024*1024, and so on for
T, P, E, Z, Y.
