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

greptogrep --color=always? SettingGREP_OPTIONSis risky. It's not only completion scripts that are affected.GREP_OPTIONShas since I switched. That forum post says that aliases don't affect scripts, but I've found that to be false.GREP_OPTIONSaffects every instance ofgrep, but aliases only affect your interactive shell. For aliases to affect scripts, the script has to enable them. And if a script does enable them, then it has no way of knowing what it's running.echo $GREP_OPTIONSthat it was indeed unset.
