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

(2)-dwill help the second command in another way. Currently, if it is executed in a directory where there are no text (.txtor.tx) files, it will list all the files in the current directory. With-d, it will just say.. … (Cont’d)findcommand can be shortened tofind . -type f -regex '.*\.txt?'(assuming GNU find).
