Obtain CPU information in Linux

1. check the number of physical CPUs catproccupinfo | grep & 039; physicalid & 039; 1. check the number of physical CPUs cat/proc/cupinfo | grep 'physical ID' | sort | uniq | wc-l2, view the number of physical cores of a cpu cat/proc/cupinfo | grep' core ID' | sort | uniq-c | wc-l or cat/proc/cupinfo | grep 'CPU cores' | uniq | awk-F ": "'{print $2}' 3. check the number of logical cores of a cpu. cat/proc/cupinfo | grep 'Siblings '| uniq | awk-F ": "'{print $2}' 4. check the total number of logical cores. the number of physical cores is the product of the result obtained from 1 and 2; cat/proc/cupinfo | grep 'processor '| sort | uniq-c | wc-l5, view cpu model cat/proc/cupinfo | grep name | cut-f2-d: | uniq-c6, # cat/proc/cpuinfo | grep physical | uniq-c4 physical id: 04 physical id: 1 indicates there are two CPUs, each cpu has four logical cores (two physical cores)
