You can for sure force an array scanning and compare the value and then if value match you're looking for, then display the corresponding index you were scanning.
But for sure it woud quickly become something heavy.
What are you trying to achieve that make you have such a need of "index-from-value" search?
What is you final goal ?
Please provide more clue about the input you have and the output you want, maybe there are some more efficient solution to achieve the final goal that is behind your question.

Hi all,
In bash, is there any way of searching an array and returning the index?
