jat

James' Admin Tool

Making administering my machines slightly easier.

Features

Update APT repositories and debs that are listed by HTTP URL in a single command. No more manually downloading and install the latest versions of some software that doesn't have an APT repository. I currently use this for Slack, Zoom, Mullvad and Bluejeans. I am happy to look at other pages if you can't get them working.

Future

Read only HTTP server of ZFS snapshots

Usage

$ jat update    # apt update, upgrade, autoremove
$ jat reboot    # update + reboot
$ jat shutdown  # update + fstrim + shutdown

Configuration

Create ~/.jat.yaml

For a manual package download you need to specify:

1. url: A page to look for the latest release
2. regexp: How to extract the version number from the page downloaded from url. By default this will just look through all hrefs.
3. selector: Optional: A CSS selector to specify where to look that isn't all hrefs. For example Zoom doesn't have the version in the package name, but does have a fixed URL to download the package from, so all we need to do is find the version. We used a CSS selector to find <span class="linux-ver-text" style="display: none;">Version 5.1.412382.0614</span> and check the inner HTML against the dpkg reported version.
