Not sure about "tac" --- could you provide more details on this

"reading" of a data file ?
tac is available as a command under linux ....
$ whatis tac
tac (1) - concatenate and print files in reverse
$ whereis tac
tac: /usr/bin/tac /usr/bin/X11/tac /usr/share/man/man1/tac.1.gz
$ man tac
SYNOPSIS
tac [OPTION]... [FILE]...
DESCRIPTION
Write each FILE to standard output, last line first.
With no FILE, or when FILE is -, read standard input.
I only know that the tac command exists
but have never used it myself ....
Unfortunately, I may be forced to process the data on a Windows platform; but,
thanks Cousin for the Linux tip.
