shell.exec(mv a/m.js b/) cannot return error stdout

[TulipLi]

Node version (or tell us if you're using electron or some other framework):

16.14.0

ShellJS version (the most recent version/Github branch you see the bug on):

0.8.5

Operating system:

gitlab CI

Description of the bug:

when I run this command shell.exec('mv a/m.js b/)
and a/m.js is not exist, then will console no such file or directory,
but when I use

const res = shell.exec(`mv a/m.js b/`)
console.log('res:' + res)
// this return an empty string
// res:''

what I want is to get the error code or error message to do something.

Example ShellJS command to reproduce the error:

const res = shell.exec(`mv a/m.js b/`)
console.log('res:' + res)
// this return an empty string
// res:''

seems like delete { continue: true } can fix this issue

if (!fs.existsSync(src)) {
      common.error('no such file or directory: ' + src);
      return; // skip file
}

Did you try console.log('res:' + res.stderr)? The .stderr property is where the error message lives.

I'm going to assume the .stderr property solves this for you. Let me know if you're still seeing issues and we can look again.
