# Linux command appendix — index (Appendix 9.2)

> Source: `D-Robotics/rdk_doc` `docs/09_Appendix/linux-command-manual/` (branch `main`, `_category_.json` label = `9.2 Linux命令用法`). These are **generic Linux** command write-ups that D-Robotics bundled for beginners. This skill only **indexes back to the official pages** — it does not copy the bodies. For exact usage, give the official link or explain from standard `man` semantics. **Do not invent RDK-specific behavior** for these commands.

Doc-site URL pattern: `https://developer.d-robotics.cc/rdk_doc/Appendix/linux-command-manual/cmd_<name>`

Notes:
- 19 commands total, all standard Linux; D-Robotics includes them for convenience.
- When a real RDK-board problem appears behind one of these (APT public-key failure, TROS package not found, etc.), it is a **symptom** — route to `rdk-board-knowledge`. This appendix is only a syntax reference.
- The S-series tree (`rdk_s_doc` / `rdk_doc docs_s/`) has the same `09_Appendix/linux-command-manual/` directory with overlapping files; no separate listing needed.
