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

Using GNU Parallel:

parallel echo {1} and {2} ::: c e :::+ 3 5

Or:

parallel -N2 echo {1} and {2} ::: c 3 e 5

Or:

parallel --colsep , echo {1} and {2} ::: c,3 e,5
