Common commands are organized as follows: 
View the serial number of the motherboard: Dmidecode | Grep-i ' Serial number ' 
Detecting new hardware with hardware detection program Kuduz: 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 card information: CAT/PROC/PCI 
View video card/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 '] 
<!--more--> 
View PCI information: LSPCI (more intuitive than CAT/PROC/PCI) 

View USB devices: Cat/proc/bus/usb/devices 
Viewing the keyboard and mouse: Cat/proc/bus/input/devices 
View system hard disk information and usage: Fdisk & disk–l & DF 
To view interrupt requests (IRQ) for each device: cat/proc/interrupts 
View System Architecture: UNAME-A 
View and start the system's 32-bit or 64-bit kernel mode: isalist–v [isainfo–v][isainfo–b] 
Dmidecode viewing 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 
To view patches already applied in the current system: showrev–p

For files in "/proc", you can use the File View command to browse its contents, and the file contains system-specific information: 
Cpuinfo Host CPU Information 
DMA Host DMA Channel information 
Filesystems File System Information 
Interrupts host interrupt Information 
Ioprots host I/O port number information 
Meninfo Host Memory Information 
Version Linux memory release information 
Note: proc–process information Pseudo-filesystem process information masquerading file system
