我想从 Linux 命令行本身查看 BIOS 设置。我想避免停机。是否可以在不重新启动服务器的情况下查看 BIOS 设置？

您可以使用 biosdecode 和 dmidecode 命令从 CLI 获取 BIOS 设置。biosdecode 命令解析 BIOS 内存并打印有关所有结构的信息。dmidecode 是一个命令行工具，用于以人性化格式转储计算机的 DMI（SMBIOS）表内容。该表包含系统硬件组件的描述。它还包括其他有用信息，例如序列号和 BIOS 修订版。

如何在 Linux 上从命令行查看 BIOS 设置

打开终端应用程序。您必须以 root 身份登录才能运行命令：
$ sudo -i
或
$ su -
键入以下命令：
# dmidecode | more
示例输出：

#  dmidecode 3.0
Getting SMBIOS data from sysfs.
SMBIOS 2.7 present.

# biosdecode
”。另一个选项是运行：您还可以使用 hwinfo 等命令。它用于探测系统中存在的硬件。它可用于生成系统概览日志，稍后可用于支持。示例输出：
# hwinfo # hwinfo --short # hwinfo --disk # hwinfo --short --block # hwinfo --disk --only /dev/sdb
