[SOLVED] How can I random words from a single line

TheGeniusLOL · 11-02-2018, 12:11 AM

From

The quick brown fox

to

quick fox The brown

I tried

Code:

echo "The quick brown fox" | rev
xof nworb kciuq ehT

echo "The quick brown fox" | sort -R
The quick brown fox

Does not work. I need your expert suggestions or ideas to try.

Thanks

Getting late here. I'm too tired to do the code and shutting down for the night in a minute, but what you could do is split the sentence into an array of words, then print the array in reverse.

'sort' works on lines and you only pass one line to. One line cannot be sorted randomly. Try passing lines to it:

Code:

v="one two three four"
sort -R <(echo -e "${v// /\\n}")

Hi crts

I just tried your code

Code:

v="one two three four"
sort -R <(echo -e "${v// /\\n}") 
four
one
two
three

However, it puts each word on it's own line. To get a single line I added the fmt command at the end.

Code:

sort -R <(echo -e "${v// /\\n}") | fmt
one three two four

Thanks crts, you're awesome

Nice catch. I just noticed that you might also use 'shuf' for this task:

Code:

shuf -e one two three four

You could also have two words treated as one field:

Code:

shuf -e one "two three" four

This, however, will not be obvious if you need all output in one line and thus pipe it two 'fmt' afterwards.

Well done with shuf -e

...or a simple pipe to: tr '\n' ' '

I didn't know shuf worked with words. Thanks crts
