Link to part in long HTML file

Question

I want to create a hyperlink to a part in a long html page.

The page: https://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html

I want to create a link to the part where this gets explained: ${parameter/pattern/string}.

Answer 1

While it is possible to link to a specific part of a page, you need to have an identifier to link to.

There is no way to design a link that points to an arbitrary position on a third-party page.

Answer 2

Unfortunately, it's not possible to create links to arbitrary parts of a web page.

Fragments ("anchors") that are intended to be linked to can be designated by assigning id attribute to their tags. That elements can be referenced using fragment part of URI, i.e. the part after #.

<p id="first">First paragraph</p>
<p id="second">Second paragraph</p>
<p>Third paragraph</p>

First two paragraphs can be linked to using http://somewhere/.../#first and http://somewhere/.../#second URIs, whereas it's not possible to target third paragraph, as it does not have id attribute.
