These are cool devices: the [WayBack] LBS008AE and LBS005AE-R2, 10-100 Switches USB powered – Black Box.
Both are the size of a Raspberry Pi and USB powered.
The first is 8-port, the second 5-port. Ideal for a stack of Pis.
There are 5V powered 8-port Gigabyte switches from other vendors as well at around `1A (effectively using ~5W), but they are bigger.

A while ago, I needed to conditionally replace in files, so I used sed and a regular expression, though usually I dislike those.
However, since the system had a very basic install, there was not much choice.
Luckily back then, my Google foo returned these:
-i flag.This allowed me to do a double expression (the first matches a pattern, the second performs the actual replacement within the matching lines).
In case my Google foo in the future fails:
## https://robots.thoughtbot.com/sed-102-replace-in-place
## -i causes no backup to be saved, but does in-place replacement
## since we run under git, we can always restore
## combined with a double expression (the first matches, the second executes) this is very powerful
sed -i -e '/#.*AVOID_DAILY_AUTOCOMMITS=.*$/s/^.//' /etc/etckeeper/etckeeper.conf && git diff | more

I’ve used these excellent posts to find out which youtube-dl version started to exhibit troublesome NPO downloads, then later find the actual failing commit:
Why the effort? I needed an as recent as possible youtube-dl working on as many sites as possible because of some work preparation.
The first link is very important because brew versions and alternatives have stopped working some 6 years ago, even though they turn up high on Google searches for brew install specific version. Hence the quote from the first link:
Installing software packages on Mac is very easy with homebrew. You typically get the latest version, however often in production you do not have the latest version of a software package. Another use case is when you upgrade to the latest and you find out there is bug which blocks you doing something. In this case you would like to downgrade to the previous version until the bug is fixed.In both cases you need to install a specific version of a software package with homebrew on your Mac, which tends to be not that trivial. There is a lot of discussion about this on stackoverflow but some of them are outdated based on brew versions which is not available anymore.

Interesting read as there are at least 3 options of which I only knew the first (dd): [WayBack] Create a large file filled with zeros on Linux – twm’s blog.
