linux 获取cpu频率

lscpu | grep "CPU MHz"

cat /proc/cpuinfo | grep "cpu MHz"

sudo apt-get install cpufrequtils  # 安装工具
cpufreq-info

# 使用 lscpu 命令获取CPU频率

# 使用 /proc/cpuinfo 文件获取CPU频率
cpu_freq_proc=$(cat /proc/cpuinfo | grep "cpu MHz" | awk -F: '{print $2}' | head -n 1)

# 使用 cpufreq-info 工具获取CPU频率
cpu_freq_cpufreq=$(cpufreq-info | grep "current CPU frequency" | awk '{print $5}')
