This will not optimize processing the file. The tail command would have
to run through the entire file and save the last 100_000 lines. It
might save on RAM memory, but with today's multi-gigabyte machines, the
file would have to be gigabyte sized to overflow it. 2_000_000 lines at
80 characters each is 160_000_000 bytes (well under 1GB).
There may be two problems with this:
1. If you are running a memory hog like Vista, you may run out of
memory reading a measly 160 MB file.
2. If you are running on a server, it may be so busy that you run out
of memory.
All I can say is TITS (Try It To See).
