本文详细介绍了在Linux系统中使用命令行方式获取硬件配置信息的方法，包括CPU、内存、磁盘、BIOS版本、操作系统版本等。通过运行特定命令，用户可以轻松了解系统硬件的详细情况。
What is the command to find the system configuration on Linux operating system using command line (text) mode?
On Linux based system most of the hardware information can be extracted from /proc file system, for example display CPU and Memory information, enter:
| Tutorial details | |
|---|---|
| Difficulty | Intermediate (rss) |
| Root privileges | Yes |
| Requirements | None |
| Estimated completion time | 10 minutes |
cat /proc/cpuinfo
The following list summarizes commands to get various hardware from the system:
Linux cpu/hardware information
Use any one of the following command:
# less /proc/cpuinfo
OR
# lscpu
Sample outputs:
Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 32 On-line CPU(s) list: 0-31 Thread(s) per core: 2 Core(s) per socket: 8 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 45 Stepping: 7 CPU MHz: 1999.874 BogoMIPS: 4000.99 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 20480K NUMA node0 CPU(s): 0-7,16-23 NUMA node1 CPU(s): 8-15,24-31
Linux show free and used memory in the system
Use any one of the following command:
# cat /proc/meminfo
OR
# free
# free -m
# free -mt
# free -gt
Sample outputs:
total used free shared buffers cached Mem: 32911564 32665848 245716 168592 294192 29324484 -/+ buffers/cache: 3047172 29864392 Swap: 999420 81832 917588
You can also run top/htop/atop commands to see used and free memory and cpu usage and more:
# top
# htop
# atop
Find ram speed and max supported ram by the server
# dmidecode --type 17
# lshw -short -C memory
# perl memconf.v3.06.pl -v
Sample outputs:

OR use the following command:
# uname -mrs
# uname -a
Find out information about the Linux distribution and version
# lsb_release -a
Sample outputs:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 12.04.2 LTS Release: 12.04 Codename: precise
OR use the following command:
$ cat /etc/*release*

Say hello to lshw
The lshw is a small command line tool to extract detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and on some PowerPC machines (PowerMac G4 is known to work):
