- 1Not to detract from Stéphane's excellent answer below, but the fact that you even need multi-dimensional arrays suggests that you are doing something that shell scripts are not suited to doing (such as processing data rather than executing other programs to process that data) and should probably be using a language better suited to your task - awk, perl, or python for example. The fact that you can wrestle bash into doing something it's bad at doesn't mean that you should.cas– cas2023-08-12 12:55:01 +00:00Commented Aug 12, 2023 at 12:55

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
