Generate permutations from multiple fields (not using Python) -


i'm trying simply, using regular unix functions (that understand), , not python (i think itertools possibly me there ?) don't understand. so: several small lists of inputs (separated commas), need used generate possible permutations. example:

list 1: (i, you, we)

list 2: (want eat, want buy, want steal)

list 3: (a banana, hamburger, icecream)

so there 3 x 3 x 3 = 27 possible outputs, are:

i want eat banana

i want eat hamburger

... , on

i'm pretty sure there no 1 liner this, there simple way achieve using simple unix building blocks ?

while not technically shell commands, bash script can pretty nested loops.

#!/bin/bash  list1=("i" "you" "we") list2=("want eat" "want buy" "want steal") list3=("a banana" "a hamburger" "an icecream")  in "${list1[@]}";             j in "${list2[@]}";                             k in "${list3[@]}";                                             echo $i" "$j" "$k                     done             done     done
