How to Edit

How to Format

- _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>

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. python-3.x), 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
${@: -1}for last and${@: -2:1}for second last (and so on...). Example:bash -c 'echo ${@: -1}' prog 0 1 2 3 4 5 6prints6. To stay with this current AgileZebra's approach, use${@:$#-1:1}to get the second last. Example:bash -c 'echo ${@:$#-1:1}' prog 0 1 2 3 4 5 6prints5. (and${@:$#-2:1}to get the third last and so on...)$((...))to subtract the 1, you can simply use${@:1:$# - 1}.
