If there's one word per line, you can use shuf yourfile to output them in random order, or

shuf yourfile > tmpfile && mv tmpfile yourfile

to write the shuffled contents back into yourfile.

You can use `tr ' ' '\n' < yourfile | shuf | tr '\n' ' '` to shuffle words in a file and put all the shuffled words on one line. – that other guy Feb 11 '13 at 06:33

If there is more than one word per line, you can use this Perl one-liner:

 perl -MList::Util -e '$/=""; print join " ", List::Util::shuffle split /\s/, <>' <in.txt >out.txt

If you don't like that output file will be in single line, you can change it be one word per line: simply replace join " " with join "\n".
