I want to write down the things that I’m thinking about and doing. I’m looking to do it in a low-friction way, so that I can do it for all little interesting things that I happen to come across or do. It’s mainly for my own reference (a bit of an external brain), but any readers can gain whatever benefit they deem appropriate. :)
I hope that I’ll get to post something most days – as I go about my usual business, it’s a rare day that I don’t encounter something unfamiliar or interesting. I’m on vacation today, so maybe you’d imagine that I’d have nothing to share.
In my efforts to get
jekyll running on my Chromebook, I did need and look up
apt commands. I had found these (or their
apt-query counterparts) some years ago, but I ahd to find them again. Here’s
apt list --installed shows all installed packages. I had done some funny
things with ruby, and wanted a clean start.
apt autoremove removes all packages that are deemed “autoremovable” (meaning
they weren’t installed explicitly, and neither were any of their reverse
dependencies.) For example, say you issued
apt install jekyll and later
apt remove jekyll. There are probably a number of other packages
ruby itself) which were automatically installed and still present.
apt autoremove will get rid of those.
dpkg -S searches for the package that provides a file.
dpkg -L lists the files in a package.
