 SYNTAX

  sort  [-emubdfinrtx] [+pos1] [-pos2] [-o output] [files]

 FUNCTION

          sort merges and then sorts lines from all

          named files and writes the result on the

          standard output.

 SOME OPTIONS: 

       -b   -  ignores leading blanks (spaces and tabs)

               in field comparisons

       -f   -  folds uppercase letters onto lowercase

       -r   -  reverse sense of comparison

 Let us use the sort command on the file above.

        datafile

    9999999999999999999

    TTTTTTTTTTTTTTTTTTT

    8888888888888888888

    KKKKKKKKkkkkkkkkkkk

    1111111111111111111

    4444444444444444444

    UUUUUUUUUUUUUUUUUUU

    zzzzzzzzzZZZZZZZZZZ

 Please enter the command to sort the above file in reverse order 

 Enter here:       

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please use sort with the -r option.

 Please type sort -r datafile

 I guess I must type this for you:

FORGET1

 sort -r datafile

 Observe the result on the terminal!
