What Links (Should Be) For
Links (other than duplicate/related links) are primarily for:
- supporting documentation
Links should not stand in lieu of other content in an answer.
Here, the link might point to some canonical source (perhaps the GNU Bash Manual) that provides an official definition of "shell glob." The page still provides a local answer to the question.
You could use a [shell glob] for this.
Here, the "answer" contains no real content. It doesn't stand alone, isn't really searchable, and provides no intrinsic value. To be of any utility whatsoever, the user would have to follow the link rather than just reading the current page.
Read [Shell Globs for Fun and Profit].
How can I link to an external resource in a community-friendly way?
