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

Note that this will remove embedded (internal) quotes as well as the ones at the beginning and end. (And the;at the end of the command line is unnecessary.);at the end of the command was introduced by pasting the snipped into my terminal. It is not in the OP's snippet. I'll remove it from the snippet. There are several other things that could be optimized, but this wasn't the requirement in this question, so I keep it the way it was posted by the OP.
