[SOLVED] SED - Prefix all jpg files with full URL

Issue

I have an HTML file with local paths to images like so - /image1.jpg or /image2.png

I want to use SED to prefix a desired url to that like so - rel="nofollow noreferrer">https://example.com.

Desired result is https://example.com/image1.jpg

I tried this -

sed "s#.*.jpg#https://example.com/*.jpg#g" index.html > index2.html

The result is index2.html which finds the image names but my replacement does not use those names. How to keep that match name?

Any suggestions?

Sample Input -

<img src="Image1.jpg" alt="boat" /><figcaption>boat</figcaption>

Sample Output -

<img src="https://example.com/image1.jpg" alt="boat" /><figcaption>boat</figcaption>

Solution

Using sed

$ sed 's#="#&https://example.com#' input_file
<p><img src="https://example.com/image1.jpg" /></p>
