Loop over tuples in bash?

Question

Is it possible to loop over tuples in bash?

As an example, it would be great if the following worked:

for (i,j) in ((c,3), (e,5)); do echo \"$i and $         


        

Answer 1

But what if the tuple is greater than the k/v that an associative array can hold? What if it's 3 or 4 elements? One could expand on this concept:

###---------------------------------------------------
### VARIABLES
###---------------------------------------------------
myVars=(
    'ya1,ya2,ya3,ya4'
    'ye1,ye2,ye3,ye4'
    'yo1,yo2,yo3,yo4'
    )


###---------------------------------------------------
### MAIN PROGRAM
###---------------------------------------------------
### Echo all elements in the array
###---
printf '\n\n%s\n' "Print all elements in the array..."
for dataRow in "${myVars[@]}"; do
    while IFS=',' read -r var1 var2 var3 var4; do
        printf '%s\n' "$var1 - $var2 - $var3 - $var4"
    done <<< "$dataRow"
done

Then the output would look something like:

$ ./assoc-array-tinkering.sh 

Print all elements in the array...
ya1 - ya2 - ya3 - ya4
ye1 - ye2 - ye3 - ye4
yo1 - yo2 - yo3 - yo4

And the number of elements are now without limit. Not looking for votes; just thinking out loud. REF1, REF2
