Guide to about-system (packages/about-system-info), the cross-platform system-info CLI and library — install and run it, pick specific info blocks, JSON output, the settings file (colors, emojis, labels, display order), the cache, the shell-greeting installer, and the programmatic API. Use when working with about-system or troubleshooting it — blocks that print empty, a greeting that doesn't run on terminal start, stale or wrong values, `infoFunctions` import errors, or `--set` changes that…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Working With about-system

The CLI and library in `packages/about-system-info`, published to npm as **`about-system`** (the directory name is not the package name). It prints 30+ system metrics as one emoji line, on Linux, macOS, Windows, and Android/Termux. Full block list, settings keys, and cache TTLs live in [API.md](API.md); read it when you need an exact block name, setting path, or default.

## Setup

```bash
npx about-system              # run once, no install
npm install -g about-system   # then: about-system
about-system --install        # add it as a shell greeting
```

The package is **ESM-only** (`"type": "module"`) and ships four entry points: `.` (library), `./api` (raw info functions), `./cli`, `./types`.

## Picking the right call

| You want | Call |
| --- | --- |
| Everything, formatted | `about-system` |
| Only some blocks | `about-system cpu,ram_used,disk_used` — positional, comma-separated, no flag |
| Machine-readable output | `about-system --json` |

How to install

The exact contents, by fingerprint

mdr add opensourceagi/dev-tools-starter-agent/about-system@sha256:d1fa8b2318f8e63f

The line at the top of this page pins the label git:20260929.424c629, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
