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
grep. It implicitly considers only the part of the line before the newline, and doesn't try to match the regex pattern against it. So it never matches, there's no question about it, so no reason to show it. (And, well, grep would print the trailing newline even if it isn't there, e.g.printf 'foo' |grep .printsfoo<newline>in all systems I have.)greptocat -A?sed 's/\$$/\\n/'di differentiate a EOL$from other instances.
