How to get macOS CPU details information in the command line All In One

How to get macOS CPU details information in the command line All In One

如何通过命令行获取 macOS CPU 的详细信息

bug ❌

无法获取具体 CPU 版本型号，如 CPU 是第几代 i7

3.2 GHz 6-Core Intel Core i7 ❓

solutions

0. sysctl 🚀

Intel(R) Core(TM) i7-8700B CPU @ 3.20GHz

$ sysctl
usage: sysctl [-bdehiNnoqx] name[=value] ...
       sysctl [-bdehNnoqx] -a

# CPU 具体型号
$ sysctl machdep.cpu.brand_string
machdep.cpu.brand_string: Intel(R) Core(TM) i7-8700B CPU @ 3.20GHz

$ sysctl -a | grep machdep.cpu.brand_string
machdep.cpu.brand_string: Intel(R) Core(TM) i7-8700B CPU @ 3.20GHz

# CPU
$ sysctl -a | grep machdep.cpu

1. Node.js os module ✅

// .mjs
import os from 'node:os'
// const os = require('node:os');

// console.log(`os =`, os)
// console.log(`os.arch =`, os.arch)
/* os.arch = [Function: arch] {
  [Symbol(Symbol.toPrimitive)]: [Function (anonymous)]
} */
console.log(`os.arch() =`, os.arch())
console.log(`os.cpus() =`, os.cpus())
console.log(`os.cpus().length =`, os.cpus().length)
console.log(`os.cpus()[0] =`, os.cpus()[0])
console.log(`os.hostname() =`, os.hostname())
console.log(`os.platform() =`, os.platform())
console.log(`os.userInfo() =`, os.userInfo())
console.log(`os.version() =`, os.version())
// console.log(`os =`, os)

2. npm package

$ npm i -D systeminformation

const os = require('systeminformation');
// promises style - new since version 3
os.cpu()
  .then(data => console.log(data))
  .catch(error => console.error(error));

# macOS 不好使 ❌
$ cat /proc/cpuinfo
