read it into a variable or array and reverse that. For example in perl:
#!/usr/bin/perl -w
use strict;

# first read text file
open IN,'test.txt';
my @lines = <IN>;
close IN;

# reverse the order of our array and loop through
for (reverse @lines) {
  # reverse the characters in the line
  # reverse expects a LIST so we split $_ first
  print reverse split //,$_ ;
}
