Hello,
I'd like to ask, if the behavior of indexed array assignment using the
form: 'array[${#arr...@]}]=' is as expected.
I tested bash versions 3.1.17 and 4.0.35.
Using v3.1 an explicitly declared non array variable (global or local)
results in an empty array[0] entry.
Using v4.0 the explicitly declared local non array variable results in
an array containing only the last value assigned to the array at index
array[1].
See test script and output below.
Thank you for time and interest.
Best regards
Mart
