Required fields*
- awk uses a pattern { action } syntax. Whatever that for header does, you obviously intended to bracket the whole line in { .. }. Also "it does not work" is inadequate. What does it do, and what did you expect it to do?Paul_Pedant– Paul_Pedant2020-01-04 15:19:21 +00:00Commented Jan 4, 2020 at 15:19

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
