Commands to check System & Hardware Information
|
||||
======
|
||||
Hello linux-fanatics, in this post i will be discussing some important that will make your life as System Administrator. As we all know being a good System Administrator means knowing everything about your IT Infrastructure & having all the information about your servers, whether its hardware or OS. So following commands will help you out in extracting out all the hardware & system information.
|
||||
|
||||
#### 1- Viewing system information
|
||||
|
||||
$ uname -a
|
||||
|
||||
![uname command][2]
|
||||
|
||||
It will provide you all the information about your system. It will provide you with Kernel name of system, Hostname, Kernel version, Kernel Release, Hardware name.
|
||||
|
||||
#### 2- Viewing Hardware information
|
||||
|
||||
$ lshw
|
||||
|
||||
![lshw command][4]
|
||||
|
||||
Using lshw will show you all the Hardware information on your screen.
|
||||
|
||||
#### 3- Viewing Block Devices(Hard disks, Flash drives) information
|
||||
|
||||
$ lsblk
|
||||
|
||||
![lsblk command][6]
|
||||
|
||||
lsblk command prints all the information regarding block devices on screen. Use lsblk -a to show all the block devices.
|
||||
|
||||
#### 4- Viewing CPU information
|
||||
|
||||
$ lscpu
|
||||
|
||||
![lscpu command][8]
|
||||
|
||||
lscpu shows all the CPU information on screen.
|
||||
|
||||
#### 5- Viewing PCI information
|
||||
|
||||
$ lspci
|
||||
|
||||
![lspci command][10]
|
||||
|
||||
All the network adapter cards, USB cards, Graphics cards are termed as PCIs. To view their information use lspci .
|
||||
|
||||
lspci -v will give detailed information regarding PCI cards.
|
||||
|
||||
lspci -t will show them in tree format.
|
||||
|
||||
#### 6- Viewing USB information
|
||||
|
||||
$ lsusb
|
||||
|
||||
![lsusb command][12]
|
||||
|
||||
To view information regarding all USB controllers & devices connected to them, we use lsusb
|
||||
|
||||
#### 7- Viewing SCSI information
|
||||
|
||||
$ lssci
|
||||
|
||||
![lssci][14]
|
||||
|
||||
To view SCSI information type lsscsi. lsscsi -s will also show the size of partition.
|
||||
|
||||
#### 8- Viewing file system information
|
||||
|
||||
$ fdisk -l
|
||||
|
||||
![fdisk command][16]
|
||||
|
||||
Using fdisk -l will show information regarding the file system. Although main function of fdisk utility is to modify a file system, you can create new partitions, delete old ones ( more on that in my future tutorial).

||||

||||

检查系统和硬件信息的命令
|
||||
======
|
||||
你们好，linux 爱好者们，在这篇文章中，我将讨论一些作为系统管理员重要的事。众所周知，作为一名优秀的系统管理员意味着要了解有关 IT 基础架构的所有信息，并掌握有关服务器的所有信息，无论是硬件还是操作系统。所以下面的命令将帮助你了解所有的硬件和系统信息。
|
||||
|
||||
#### 1- 查看系统信息
|
||||
|
||||
$ uname -a
|
||||
|
||||
![uname command][2]
|
||||
|
||||
它会为你提供有关系统的所有信息。它会为你提供系统的内核名、主机名、内核版本、内核发布号、硬件名称。
|
||||
|
||||
#### 2- 查看硬件信息
|
||||
|
||||
$ lshw
|
||||
|
||||
![lshw command][4]
|
||||
|
||||
使用 lshw 将在屏幕上显示所有硬件信息。
|
||||
|
||||
#### 3- 查看块设备（硬盘、闪存驱动器）信息
|
||||
|
||||
$ lsblk
|
||||
|
||||
![lsblk command][6]
|
||||
|
||||
lsblk 命令在屏幕上打印关于块设备的所有信息。使用 lsblk -a 显示所有块设备。
|
||||
|
||||
#### 4- 查看 CPU 信息
|
||||
|
||||
$ lscpu
|
||||
|
||||
![lscpu command][8]
|
||||
|
||||
lscpu 在屏幕上显示所有 CPU 信息。
|
||||
|
||||
#### 5- 查看 PCI 信息
|
||||
|
||||
$ lspci
|
||||
|
||||
![lspci command][10]
|
||||
|
||||
所有的网络适配器卡、USB 卡、图形卡都被称为 PCI。要查看他们的信息使用 lspci。
|
||||
|
||||
lspci -v 将提供有关 PCI 卡的详细信息。
|
||||
|
||||
lspci -t 会以树形格式显示它们。
|
||||
|
||||
#### 6- 查看 USB 信息
|
||||
|
||||
$ lsusb
|
||||
|
||||
![lsusb command][12]
|
||||
|
||||
要查看有关连接到机器的所有 USB 控制器和设备的信息，我们使用 lsusb。
|
||||
|
||||
#### 7- 查看 SCSI 信息
|
||||
|
||||
$ lssci
|
||||
|
||||
![lssci][14]
|
||||
|
||||
要查看 SCSI 信息输入 lsscsi。lsscsi -s 会显示分区的大小。
|
||||
|
||||
#### 8- 查看文件系统信息
|
||||
|
||||
$ fdisk -l
|
||||
|
||||
![fdisk command][16]
|
||||
|
||||
使用 fdisk -l 将显示有关文件系统的信息。虽然 fdisk 的主要功能是修改文件系统，但是也可以创建新分区，删除旧分区（详情在我以后的教程中）。
|
||||
|
||||
就是这些了，我的 Linux 爱好者们。建议你在**[这里][17]**和**[这里][18]**查看我文章中关于另外的 Linux 命令。
