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
sedon data that is not text, usingsedwith unsanitized shell variables, needless testing for directory beforemkdir -p, and reading the output fromfindwith newline as the delimiter even though pathnames may contain newlines. There is also an issue if the source path is a substring of the destination path. You also do not consider the actual questions posed by the asker.
