命令参考¶

全部命令，顺序与 kl-help 打印的一致。kl- 形式是你在提示符下敲的，也是本表和教程展示的形式；规范的 kernlens- 形式是注册名，脚本可以用它，第二列也列出它，以防将来别名被改名。两者始终都能用。

本页由 tools/gen_commands.py 从 tools/tutorial_meta.json 生成；要改就改命令的 parser 描述，不要改这张表。每个命令在 tutorial/ 里有一页，附捕获的输出与阅读方法（页面本身保留英文）。

分类名、命令名与一句话描述保留英文。 它们就是 kl-help 打印的那些字符串，命令只认这一套拼写；把它们翻译一份，只会得到一套没有任何命令响应的名字。
