node.js - node exec 执行没反应

Question

const exec = require('child_process').exec;
          exec('cat /dev/urandom |od -x|head -n 1', (error, stdout, stderr) => {
            if (error) {
              console.error(`exec error: ${error}`);
              return;
            }
            console.log(`stdout: ${stdout}`);
            console.log(`stderr: ${stderr}`);
          });

为什么执行这段语句，完全没反应？

而在终端执行完全正常。

Answer 1

The default maximum allowed amount of data output to stdout and stderr by exec does not exceed 200K. If it exceeds, the child process will be killed.
