- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line

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

functionkeyword when used with()for a function definition serves no purpose except to make your script less portable. thefunctionkeyword automatically automatically ignores the definition anyway and it winds up parsed as if thefunctionkeyword were not used at all. but your script is really good - and i think its awesome you came back to answer your own question. 9 times out of 10, these are the best answers.main(){ ...; }rather thanfunction main(){ ...; }because the latter form doesn't work in as many host shells as the former, and the latter doesn't offer any advantage over the former in those in which it does. the other way to do it isfunction main { ...; }but that is only useful if you want to localizetraps and variables per function. the variables can be fairly portably localized with thelocalbuiltin declaration command, anyway, by the way.
