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

atq | awk "{print \$1}"- sometimes there are reasons you want the double quote, and in that case, escaping the$is necessary. Contrived example:prefix="foo: "; atq | awk "{print $prefix, \$1}". Granted, that would normally be better accomplished usingawks-v variable=...syntax, but it can still be useful sometimes...awkcode. To use a shell variable in anawkprogram, import it using-v var="$var"orexportit and access it throughENVIRON["var"]. Using single quotes aroundawkcode is always possible and always what you'd want to do.
