I've been looking for a CLI system information tool without unnecessary dependencies for a while.
The most known ones are, of course neofetch and screenfetch. The former hasn't been packaged for NetBSD, but the later can be found in the repos, although it will pull bash as a dependency.
A simpler tool can be found in ufetch, but this one has currently no support for NetBSD.
So, I've pulled some files from the gitlab ufetch repo and hacked the code for it to work on NetBSD.
You can fetch it from my github repo, run chmod +x ufetch on the file and move it to /usr/pkg/bin
Now you can issue $ ufetch from the terminal in order to display system information.
Have a good weekend!
