ubuntu 下 cpu 信息存储在 /proc/cpuinfo 文件中（一切皆文件嘛），直接通过 cat /proc/cpuinfo 就能看到所有的信息。不过，通常情况下 CPU 的核心数都比较多，直接查看这个文件会得到很长的输出结果，找到想要的信息比较困难。
下面是我的笔记本 CPU 信息： AMD Ryzen 7 4800H 。
所有命令均在
WSL下运行，得到结果可能与纯ubuntu机器略有差异。

所以这里总结一些常用的查看命令
查看 CPU 型号
$ cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c 16 AMD Ryzen 7 4800H with Radeon Graphics点击复制复制失败已复制
查看物理 CPU 颗数
$ cat /proc/cpuinfo | grep "physical id" | uniq -c 16 physical id : 0点击复制复制失败已复制
查看 CPU 运行模式
$ getconf LONG_BIT 64点击复制复制失败已复制
提示
这里我的机器运行结果显示 64 ，有些可能显示 32 ，显示 32 的不代表CPU 不支持 64 位，只是表示当前是运行在 32 位模式下。
