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
$fooand$barshould already be results fromrealpath, so you could use$fooand$bardirectly instead of$rd1and$rd2/before the*, right? Also, man bash says there is no word splitting inside[[ ]], could I drop the double quotes there?/is needed. The quotes are not needed. I always follow: if in doubt: quote. I'll update.foo="$(...)". The man is not very explicit about word splitting of the result of$(); I understand this result may be split according to the context, hence there is no word splitting here because variable assignments do not induce word splitting. Thanks again!
