shuffle pack of words in line
hello
i just seeking for a simple way to make a shuffle by block of words in a line. no matter shell (sh/bash) or perl

should be like this:
the message (which is line of some file) splits to packs (packs are random 5-10 words in each) then making a new line inserting those packs in a random order. then goes to next line in file
simple as that Smilie

This requirement does not seem to bear any significance in the real world.

Is this a homework question?

What does the input file look like?

What should the output look like?

example:
input file is full of lines such like this:
the message (which is line of some file) splits to packs (packs are random 5-10 words in each) then making a new line inserting those packs in a random order. then goes to next line in file

output file should be:
making a new line inserting those order. then goes to next line in file splits to packs (packs are random the message (which is line of some file) 5-10 words in each) then packs in a random

then next line in those file is another line of words

it should be pretty easy on perl with hes regexp and arrays
but should be not hard with awk too. maybe 1 line even
atm i'm trying to make this script on shell by making array and then take 5-10 random array elements and make a new message but this will be alot of code

Code:
randomize()
{
  set -f
  set -- $1
  set +f
  while [ $# -ge 5 ]
  do
    pack+=( "$1 $2 $3 $4 $5" )
    shift 5
  done

  if [ $# -gt 0 ]
  then
    pack+=( "$*" )
  fi

  while [ ${#pack[@]} -gt 0 ]
  do
    n=$(( $RANDOM % ${#pack[@]} ))
    printf "%s " "${pack[$n]}"
    unset pack[$n]
    pack=( "${pack[@]}" )
  done
  echo
}

I can think of at least one important site who would have a fit at this thread.

The Spamhaus Project

Hopefully the attempt to crack the spam filters will result in a block.
