你可以在nodejs中执行同步shell操作，如下所示:

var execSync = function(cmd) {

    var exec  = require('child_process').exec;
    var fs = require('fs');

    //for linux use ; instead of &&
    //execute your command followed by a simple echo 
    //to file to indicate process is finished
    exec(cmd + " > c:\\stdout.txt && echo done > c:\\sync.txt");

    while (true) {
        //consider a timeout option to prevent infinite loop
        //NOTE: this will max out your cpu too!
        try {
            var status = fs.readFileSync('c:\\sync.txt', 'utf8');

            if (status.trim() == "done") {
                var res = fs.readFileSync("c:\\stdout.txt", 'utf8');
                fs.unlinkSync("c:\\stdout.txt"); //cleanup temp files
                fs.unlinkSync("c:\\sync.txt");
                return res;
            }
        } catch(e) { } //readFileSync will fail until file exists
    }

};

//won't return anything, but will take 10 seconds to run
console.log(execSync("sleep 10")); 

//assuming there are a lot of files and subdirectories, 
//this too may take a while, use your own applicable file path
console.log(execSync("dir /s c:\\usr\\docs\\"));

5年来，我的方法是有两条线;

const { execSync } = require('child_process');
const shell = (cmd) => execSync(cmd, {encoding: 'utf8'});

然后享受: Shell ('git remote -v') 或 Out = shell('ls -l') . .等等

使用ShellJS模块。

不提供回调函数的Exec函数。

例子:

var version = exec('node -v').output;

我习惯于在回调函数的末尾实现“同步”的东西。不是很好，但是很有效。如果您需要实现一系列命令行执行，则需要将exec包装到某个命名函数中并递归调用它。 这个模式对我来说似乎很有用:

SeqOfExec(someParam);

function SeqOfExec(somepParam) {
    // some stuff
    // .....
    // .....

    var execStr = "yourExecString";
    child_proc.exec(execStr, function (error, stdout, stderr) {
        if (error != null) {
            if (stdout) {
                throw Error("Smth goes wrong" + error);
            } else {
                // consider that empty stdout causes
                // creation of error object
            }
        }
        // some stuff
        // .....
        // .....

        // you also need some flag which will signal that you 
        // need to end loop
        if (someFlag ) {
            // your synch stuff after all execs
            // here
            // .....
        } else {
            SeqOfExec(someAnotherParam);
        }
    });
};

参见execSync库。

用node-ffi很容易做到。我不推荐服务器进程，但对于一般的开发实用程序，它可以完成任务。安装库。

npm install node-ffi

示例脚本:

var FFI = require("node-ffi");
var libc = new FFI.Library(null, {
  "system": ["int32", ["string"]]
});

var run = libc.system;
run("echo $USER");

[编辑2012年6月:如何获得STDOUT]

var lib = ffi.Library(null, {
    // FILE* popen(char* cmd, char* mode);
    popen: ['pointer', ['string', 'string']],

    // void pclose(FILE* fp);
    pclose: ['void', [ 'pointer']],

    // char* fgets(char* buff, int buff, in)
    fgets: ['string', ['string', 'int','pointer']]
});

function execSync(cmd) {
  var
    buffer = new Buffer(1024),
    result = "",
    fp = lib.popen(cmd, 'r');

  if (!fp) throw new Error('execSync error: '+cmd);

  while(lib.fgets(buffer, 1024, fp)) {
    result += buffer.readCString();
  };
  lib.pclose(fp);

  return result;
}

console.log(execSync('echo $HOME'));
