At the page https://developer.android.com/studio/index.html, there is a link to the Android SDK tools for Linux, which I'd like to download by a script. Unfortunately, there is no "easy" link to use to download the latest version, so I'd like to extract the link from the HTML itself.
The link is identified by the id linux-tools and is contained on multiple lines:
<a onclick="return onDownload(this)" id="linux-tools" data-modal-toggle="studio_tos"
href="https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip">sdk-tools-linux-38593
I'd like to extract that href into a variable in a Bash script. The closest I've gotten so far is the following:
grep -o -z '<a.[^<]*id="linux-tools"[^<]*</a>' index.html
which outputs the above two lines.
How do I get at the actual link using typically-available shell commands?
