东芝307打印机怎么启动看这里!10 个用于收集硬件信息的 Linux 命令

1.如何查看Linux系统信息

如果只想知道系统名称，可以使用不带参数选项的uname命令输出系统信息，或使用uname -s命令输出系统的内核名称。

tecmint@tecmint ~ $ uname Linux

要查看网络主机名，用“-n”参数选项的uname命令，如下所示。

tecmint@tecmint ~ $ uname -n

要获取有关内核版本的信息，使用“-v”参数选项。

tecmint@tecmint ~ $ uname -v #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014

要得到有关你的内核的发行版信息，请使用“-r”参数选项。

tecmint@tecmint ~ $ uname -r 3.13.0-37-generic

要输出你的机器的硬件名，使用“-m”参数选项：

tecmint@tecmint ~ $ uname -m x86_64

所有这些信息可以通过运行“uname -a”命令，如下图所示一次性输出。

tecmint@tecmint ~ $ uname -a Linux 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

2.如何查看Linux的系统硬件信息

你可以使用lshw工具来收集有关硬件部件，如CPU，硬盘，内存，USB控制器等的大量信息。

lshw是一个相对比较小巧的工具，当你提取信息的时候，只有为数不多的几个选项可供你使用。由lshw提供的信息收集形成了不同的/ proc文件。

注：请记住，lshw命令是由superuser （root）或sudo用户执行的。

参见：《Difference Between su and sudo User in Linux》

要输出你的Linux系统的硬件信息，运行此命令。

tecmint@tecmint ~ $ sudo lshw description: Notebook product: 20354 (LENOVO_MT_20354_BU_idea_FM_Lenovo Z50-70) vendor: LENOVO version: Lenovo Z50-70 serial: 1037407803441 width: 64 bits capabilities: dmi-2.7 vsyscall32 configuration: administrator_password=disabled boot=normal chassis=notebook family=IDEAPAD frontpanel_password=disabled keyboard_password=disabled power-on_password=disabled sku=LENOVO_MT_20354_BU_idea_FM_Lenovo Z50-70 uuid=E4B1D229-D237-E411-9F6E-28D244EBBD98 *-core description: Motherboard product: Lancer 5A5 vendor: LENOVO physical id: 0 version: 31900059WIN serial: YB06377069 slot: Type2 - Board Chassis Location *-firmware description: BIOS vendor: LENOVO physical id: 0 version: 9BCN26WW date: 07/31/2014 size: 128KiB capacity: 4032KiB capabilities: pci upgrade shadowing cdboot bootselect edd int13floppynec int13floppytoshiba int13floppy360 int13floppy1200 int13floppy720 int13floppy2880 int9keyboard int10video acpi usb biosbootspecification uefi ......

你可以通过使用-short选项来输出汇总的硬件信息。
