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

sudois completely superfluous.sudo? No. Note that the user is single-quoting the$2and that there is no indication what the difference between "running this on a Linux machine" and "running this in the terminal" is (or even what "this" is). Thesudois a red herring and we don't know what the actual issue is.sudo(not without jumping through several hoops and opening yourself to security issues). I was thinking there may have been an issue withsshconsumingstdinwhich is why the password prompt wasn't appearing, but I think I was just completely wrong. I read the question as the command working when executed directly but failing when used as a function.
