Is there an easy way to randomize all the words in a given text? Maybe in BASH?

I want to randomize all the words in a given text, so that I can input a file with English like 

"The quick brown fox jumped over the lazy dogs."

and have it output: 

"fox jumped lazy brown The over the dogs. quick"

The easiest way I can think to do it would be to import the text into python, put it into a dictionary with a seqence of numbers as keys, then randomize those numbers and get the output. Is there an easier way to do this, maybe from the command-line, so that I don't have to do too much programming?

Quick Solution:

You can randomize lines with sort -R in bash. tr will do string replacement.

example:

echo ".." | tr -s " " "\n" | sort -R | tr "\n" " "; echo

will randomize a string separated by spaces.

Another variation would be converterting all non alphanumerical characters to newlines 

| tr -cs 'a-zA-Z0-9' '\n'

explanation:

# tr -c       all NOT matching 
# tr -s       remove all dublicates )

-> randomimizing the lines

| sort -R

-> replacing all newlines with spaces

| tr "\n" " "

-> removing the last space with sed

| sed "s/ *$//"

and finally adding a dot ( and a newline )

; echo "."

Finally : A function to make a real new sentence from another sentence

Features ignoring dublicate space and removing all non-alphanumeric

reading the output makes you sound like master yoda ...

sentence="This sentence shall be randomized...really!"

echo $sentence | tr -cs 'a-zA-Z0-9' '\n' | sort -R | tr "\n" " " | sed "s/ *$//"; echo "."

Output examples:

randomized This shall be sentence really.
really be shall randomized This sentence.

...

Addition: sed explaination ( i know you want it ... )

sed "s/bla/blub/"           # replace bla with blub
sed "s/bla*$/blub/"         # replace the last occurence of bla with blub
sed "s/ *$//"               # -> delete last space aka replace with nothing

would only shuffle the words.

Using Python, from a bash prompt:

echo "The quick brown fox jumped over the lazy dogs." | \
python -c "import random, sys; x = sys.stdin.read().strip().split(' '); \
random.shuffle(x); sys.stdout.write('\"{}\"\n'.format(' '.join(x)))"

In Python:

>>> import random
>>> s = "I want to randomize all the words in a given text, so that I can input a file with English like "
>>> words = s.split()
>>> random.shuffle(words)
>>> ' '.join(words) 
'words I so like a can the text, I want a randomize input given with to in all that English file'

quick and dirty:

echo ".."|xargs -n1 |shuf|paste -d' ' -s

your example:

kent$  echo "The quick brown fox jumped over the lazy dogs."|xargs -n1 |shuf|paste -d' ' -s
the jumped quick dogs. brown over lazy fox The

if you don't have shuf, sort -R would work too. same idea.
