Add . html extension at the end of all links in multiple files (with Shell Script)

Hello.

I have a lot of HTML files that have links in the following format: http://localhost:8080/tag:alguma_coisa and I need to add the extension .html to these links so that they stay like this: http://localhost:8080/tag:alguma_coisa.html.

I’ve tried several combinations with findand sed but with none of them I got the expected result.

Does anyone have any idea how to do this with Shell Script?

    Are the contents of these files just links? Or are there other things (comments, blank lines, etc...)?

  • It’s HTML source code. What I need is to get all attributes of html tags in the format nome_atributo="tag:algumacoisa" and trade for nome_atributo="tag:algumacoisa.html". For example, I have <a href="tag:city"> and I need to exchange for <a href="tag>city.html">

Considering files in the current directory in . html format and that within these files there are only links, would look like this:

find . -type f -name *.html -exec sed 's/$/.html/g' {} \;

  • I used the command find . -type f -name "*.htm" -exec sed '/tag:.*"/ s/tag:.*"/&.html/g' {} \; and it was as close as I could get, because the result was this: The original pattern was <a href="tag:city">city</a> and I managed to put the .htmlin the end, like this: <a href="tag:city".html>city</a>. The problem is that he was out of quotation marks.
