Linux中如何获取CPU缓存的大小

bash
#!/bin/bash
cpu_cores=$(grep -P '^processor\t' /proc/cpuinfo | wc -l)
for ((i=0; ido
    cache_size=$(cat /sys/devices/system/cpu/cpu$i/cache/index2/size)
    echo "CPU Core $i Cache Size: $cache_size"
done

bash
#!/bin/bash
cpu_cores=$(lscpu | grep -P '^CPU\(s\):' | awk '{print $2}')
for ((i=0; ido
    cache_size=$(lscpu | grep -P "^L$i Cache" | awk '{print $3, $4}')
    echo "CPU Core $i Cache Size: $cache_size"
done
