How to Edit

How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
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

f2() ( … )being executed in a subshell and outside the current running environment is one thing and the freedom to localize some and not other vars as well as inherit others is another thing.compound-commandis not limited to{ ...; }and(...), there are many others includingwhile/forloops,case/ifconstructs and even... function definitions. For example,f() g() for i do w; donedefines affunction that defines agfunction as aforloop.f() g() { : ;}like they reject functions with simple command as body.( ){ }differences (which I have exploited and/or misused), how am I just learning about the redirect part?!f() { echo hello ; } >/tmp/foofile. I really should RTFM.
