We welcome edits that make the post easier to understand and more valuable for readers. Because community members review edits, please try to make the post substantially better than how you found it, for example, by fixing grammar or adding additional resources and hyperlinks.
How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- 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
sortcommand externally? Does anyone know of at least a link to a page explaining pipe use within awk?sort:sort -n -k 2b,2 -t $'\t'. The problem is nesting'\t'inside'NR...{print...}'. The explanation of how to escape the's is here-boption, as it will makesortignore leading blanks in the sort key. The default field separator is non-blank-to-blank transitions, so fields will start with leading blanks. For example, this command lists installed Python packages first by location, then by package name:pip list -v | awk 'NR <= 2; NR > 2 { print $0 | "sort -b -k 3,3 -k 1,1" };'awkmay need to be followed byclose("sort --exact-args...")to prevent buffering from printing this after later prints.
