reversing lines

[Stephen P. Kemp]

On 4.2 bsd systems, the following will work (I think there are no restrictions
regarding the file contents):

     % cat -n filename | sort -nr | sed "s/^.......//" 

cat -n prefixes the input with lines numbers; sort -nr sorts using the numbers
as the sort key, and outputs the lines in reverse order; sed strips the 
line numbers off again and the result ought to be what you want.
