One Day One GNU/Linux Command
=============================
tac -- Concatenate and Print files in reverse order.
Summary:
`tac' copies each file to standard output, reversing the records
(lines by default) in each separately. It is doing the reverse
function of the CAT command (TAC).
Example:
$ tac myfile -- Print the file (Line by Line) in reverse order.
$ tac -r -s '[^a-zA-z0-9\-]' myfile -- Print the file (Word by Word)
in reverse order, by passing the Regular expression.
$ tac -r -s '.\|' myfile -- Print the file (Char by Char) in reverse
order.
Read: man tac
HTH :)
