lscpu command

• lscpu in Linux/Unix is used to display CPU Architecture info. lscpu gathers CPU architecture information from sysfs and /proc/cpuinfo files. For example :

          manish@godsmack:~$ lscpu

Option

-a, --all Include lines for online and offline CPUs in the output (default for -e). This option may only specified together with option -e or -p. For example: lsof -a -b, --online Limit the output to online CPUs (default for -p). This option may only be specified together with option -e or -p. For example: lscpu -b -c, --offline Limit the output to offline CPUs. This option may only be specified together with option -e or -p. -e, --extended [=list] Display the CPU information in human readable format. For example: lsof -e
