How to Edit
- Correct minor typos or mistakes

- Don’t use edits to reply to the author
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
lang-bash
filecommand is not overly reliable. For example, create a script that starts with twenty comment lines other than#!/bin/bash.filewill categorize it as ASCII text (at least my version offiledoes).file, you can generate the list of shell scripts withfile * | grep shell | cut -f1 -d:(assuming filenames don't contain colons). You step through this list with aforloop and rename the files.#!/bin/bashline must always be the first line; anything not on the first line is ignored (and the kernel will run the script with/bin/sh)
