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
\bhelps keep the\nbecause then the newline isn't a trailing newline, it now has one more character after it.for x in *.mp3is better and shorter, and works with any valid filename. parrsinglsdoesn't, no matter how you set IFS. Also, you don't need theecho -en"\n\b"trick, you can just useIFS=$'\n'- that still won't make parsing ls a good idea, but at least it's not a work-around for a self-made problem.
