This article mainly introduces what the LINUX view hardware configuration commands have, which has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to know about it.

LINUX View hardware configuration command

Linux system under some configuration view commands, very practical, do not remember where to see it, sort it over, hope to be useful!

System

# uname-a # View kernel / operating system / CPU information

# head-n 1 / etc/issue # View operating system version

# cat / proc/cpuinfo # View CPU information

# hostname # View computer name

# lspci-tv # list all PCI devices

# lsusb-tv # list all USB devices

# lsmod # list the loaded kernel modules

# env # View environment variables

Resources

# free-m # View memory usage and swap area usage

# df-h # View the usage of each partition

# du-sh # View the size of the specified directory

# grep MemTotal / proc/meminfo # check the total memory

# grep MemFree / proc/meminfo # check the amount of free memory

# uptime # View system running time, number of users, and load

# cat / proc/loadavg # View system load

Disks and partitions

# mount | column-t # to view the status of attached partitions

# fdisk-l # View all partitions

# swapon-s # View all swap partitions

# hdparm-I / dev/hda # View disk parameters (for IDE devices only)

# dmesg | grep IDE # check the detection status of IDE devices at startup

The network

# ifconfig # View the properties of all network interfaces

# iptables-L # View firewall settings

# route-n # View the routing table

# netstat-lntp # View all listening ports

# netstat-antp # View all established connections

# netstat-s # View network statistics

Process

# ps-ef # View all processes, and filter out a process with grep

# top # Real-time display of process status

User

# w # View active users

# id # View specified user information

# last # View user login log

# cut-d:-F1 / etc/passwd # View all users of the system

# cut-d:-F1 / etc/group # View all groups of the system

# crontab-l # View the current user's scheduled tasks

Service

# chkconfig-- list # list all system services

# chkconfig-- list | grep on # lists all started system services

program

# rpm-qa # View all installed packages

Common commands are organized as follows:

Check the serial number of the motherboard: dmidecode | grep-I 'serial number'

Use the hardware detector kuduz to detect new hardware: service kudzu start (or restart)

View CPU information: cat / proc/cpuinfo [dmesg | grep-I 'cpu'] [dmidecode-t processor]

View memory information: cat / proc/meminfo [free-m] [vmstat]

View board information: cat / proc/pci

View video / sound card information: lspci | grep-I 'VGA' [dmesg | grep-I' VGA']

View Nic information: dmesg | grep-I 'eth' [cat / etc/sysconfig/hwconf | grep-I eth] [lspci | grep-I' eth']

View PCI information: lspci (more intuitive than cat / proc/pci)

View USB devices: cat / proc/bus/usb/devices

View keyboard and mouse: cat / proc/bus/input/devices

Check the hard disk information and usage of the system: fdisk & disk-l & df

View interrupt requests (IRQ) for each device: cat / proc/interrupts

View the system architecture: uname-a

View and boot the 32-bit or 64-bit kernel mode of the system: isalist-v [isainfo-v] [isainfo-b]

Dmidecode views hardware information, including bios, cpu, memory, etc.

Determine the current display refresh rate: / usr/sbin/ffbconfig-rev\?

View system configuration: / usr/platform/sun4u/sbin/prtdiag-v

Check out the patches that have been applied on the current system: showrev-p

Displays the current run level: who-rH

View the current bind version information: nslookup-class=chaos-q=txt version.bind

Dmesg | more to view hardware information

Lspci displays peripheral information, such as usb, network card, etc.

Lsnod to view loaded drivers

Lshw

Psrinfo-v to view the type and speed of the current processor (dominant frequency)

Prtconf-v prints the current OBP version number www.2cto.com

Iostat-E to view hard disk physical information (vendor, RPM, Capacity)

Prtvtoc / dev/rdsk/c0t0d0s view the geometric parameters and partition information of the disk

Df-F ufs-o I shows the number of i-node used and unused

Files in "/ proc" can be browsed using the file view command, which contains system-specific information:

Cpuinfo host CPU information

Dma host DMA tunnel information

Filesystems file system information

Interrupts host interrupt information

Ioprots host IZP O port number information

Meninfo host memory information

Version Linux memory version information

Note: proc-process information pseudo-filesystem process information camouflage file system
