If you want more help with Bash in the future, this is the best resource I’ve found in 13 years of writing bash professionally: https://mywiki.wooledge.org/EnglishFrontPage

Bash FAQs and pitfalls are the primary sections to look at there.

Thank you for providing the easiest and most portable answer. This will handle files with special characters perfectly unlike most of the responses here which rely on a while loop (to say nothing of a for loop ).

Shell scripts are one of the worst possible applications of an LLM. They’re trained on shit fucking GitHub scripts, and they give you shit in return.

You may have a bit of a hard time finding something that’s completely FLOSS that’s not on the older side (the sar visualizer being a Java desktop application being a consequence of that age). There are various ways to dump resource usage into a time series database like Prometheus (Apache2), InfluxDB (Apache2/MIT), or VictoriaMetrics (Apache2) and then visualize it with a frontend (Grafana, APGL). The database is going to be the tricky part. All of the time series DBs I’m aware of are permissively licensed. Grafana may be a good fit for you, however. It’s written in Go so it’s relatively light, although it obviously requires a browser to interact with.

Arch is a pretty good one if you want to control and tinker. I have personally found it to be very reliable over the years, and the AUR is exceptionally powerful (although you NEED to review your PKGBUILDs, there’s nothing stopping someone from putting malware on the AUR again). The packaging format is so simple and easy that I actually build a few performance-critical packages locally so I can tweak compiler flags (gimmie that -march native).

Nix is cool and kinda crazy, but honestly? I’d hold off until you’re comfortable with Arch. Same with Gentoo.

It does, the repo is tagged as AGPL.
