Commands to get CPU information and memory info in Ubuntu Linux. On Ubuntu Linux, check CPU cores or CPU info. Use these commands to check ram and processor details in Linux Ubuntu Systems.
lscpu
lscpu command displays information about the CPU architecture. lscpu gathers CPU architecture information from sysfs and /proc/cpuinfo. The command output can be optimized for parsing or for easy readability by humans.
The information includes, for example, the number of CPUs, threads, cores, sockets, and Non-Uniform Memory Access (NUMA) nodes. There is also information about the CPU caches and cache sharing, family, model, bogoMIPS, byte order, and stepping.
$ lscpu
cpuinfo
proc is the process information pseudo-filesystem. The proc filesystem is a pseudo-filesystem which provides an interface to kernel data structures.
It is commonly mounted at /proc. Most of it is read-only, but some files allow kernel variables to be changed. The cpuinfo shows a detail information about the CPU.
$ cat /proc/cpuinfo
inxi
inxi is a full featured CLI system information tool. It is available in most Linux distribution repositories, and also runs somewhat on BSDs. The primary purpose of inxi is for support, and sys admin use. inxi is a command line system information script built for for console and IRC.
It is also used for forum technical support, as a debugging tool, to quickly ascertain user system configuration and hardware. inxi shows system hardware, CPU, drivers, Xorg, Desktop, Kernel, GCC version(s), Processes, RAM usage, and a wide variety of other useful information.

$ inxi -C
lshw
lshw stands for list hardware. lshw is a small 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).
It currently supports DMI (x86 and IA-64 only), OpenFirmware device tree (PowerPC only), PCI/AGP, CPUID (x86), IDE/ATA/ATAPI, PCMCIA (only tested on x86), SCSI and USB.
$ sudo lshw -C CPU
