Bash: unusual line break

Question

I coded a small script in bash, which read some HTML and should print the href of a link:

#!/bin/bash

link=$(echo $source | sed -ne 's#^.*<a href="\([^"]*\)".*$#\1#p')

  if [ "$(echo "$link" | grep '/fonts/list/style')" ]
    then
      echo "http://www.domain.com$link/10000"
  fi

The var source is in my example:

<li><span>19</span><a href="/fonts/list/style/home words">linktext</a></li>

The Problem: The script print not

http://www.domain.com/fonts/list/style/home words/1000

instead of it prints

http://www.domain.com/fonts/list/style/home
words/1000

How can I remove or avoid this line break?

Answer 1

You have to escape the " appearing in the <li>...:

This worked to me:

#!/bin/bash

source="<li><span>19</span><a href=\"/fonts/list/style/home words\">linktext</a></li>"

link=$(echo $source | sed -ne 's#^.*<a href="\([^"]*\)".*$#\1#p')

  if [ "$(echo "$link" | grep '/fonts/list/style')" ]
    then
      echo "http://www.domain.com$link/10000"
  fi

Output

http://www.domain.com/fonts/list/style/home words/10000
