输出特定的系统信息。如果不带 <选项>，则视为使用了 -s 选项。
-a, --all 按如下次序输出所有信息，其中若 -p 和 -i 的
探测结果为未知，则省略：
-s, --kernel-name 输出内核名称
-n, --nodename 输出网络节点的主机名
-r, --kernel-release 输出内核发行号
-v, --kernel-version 输出内核版本号
-m, --machine 输出主机的硬件架构名称
-p, --processor 输出处理器类型（不可移植）
-i, --hardware-platform 输出硬件平台（不可移植）
-o, --operating-system 输出操作系统名称
