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

In cases where my tuple definitions are more complex, I prefer to have them in a heredoc:

while IFS=", " read -ra arr; do
  echo "${arr[0]} and ${arr[1]}"
done <

This combines looping over lines of a heredoc with splitting the lines at some desired separating character.
