```
like so
``` -

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
-lif you don't want the information it prints. Or remove the first line with e.g.sed 1d. Or use the shell's arithmetic expansion to subtract one,$(( $(wc -l) - 1 )). But also note that if someone gives you a filename with a newline in it (something unix-like OSes sadly don't stop you from doing), some versions oflswill happily print it with a raw newline, messing up the count. Anyway, you should probably turn that into a shell function too, in particular because"$@"doesn't even work in an alias the way you'd hope it does.
