CPU

  • 查看CPU核心数执行命令：
lscpu|grep "CPU(s):"
  • 查看CPU核心数也可以通过：
cat /proc/cpuinfo|grep processor

看到的CPU个数确认，如果是4核CPU，则可以看到processor0到processor3共计4个CPU信息

  • 查看CPU型号：
cat /proc/cpuinfo |grep "name" |cut -f2 -d: |uniq -c
  • 查看CPU运行在多少位
 getconf LONG_BIT
  • 按cpu利用率从大到小排序
ps -e -o “%C:%p:%z:%a”|sort -nr
