What steps will reproduce the bug?

Just call statSync() on node_modules/.bin/mocha:

import fs from "node:fs"

const mocha = "<abs path>/node_modules/.bin/mocha";
const stat = fs.statSync(mocha);
console.log(`File: ${stat.isFile()}, Link: ${stat.isSymbolicLink()}`);

Result:

File: true, Link: false

But if I run in bash:

ls -l <abs path>/node_modules/.bin/mocha
stat <abs path>/node_modules/.bin/mocha

Result:

lrwxrwxrwx 1 user group 21 20 apr 08.33 <abs path>/node_modules/.bin/mocha -> ../mocha/bin/mocha.js

File: <abs path>/node_modules/.bin/mocha -> ../mocha/bin/mocha.js

So it is truly a symbolic link.

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

it should say that it is a link and not a regular file

What do you see instead?

It says it is a regular file

fs.stat follows symlinks. You need to call lstat if you don't want this behavior

Hi,

yes you are right I missed it in the doc.
Maybe it is possible to explicitly write this in the documentation of all stat() function variants (stat, promises.stat(), etc.), so it will be clearer? (I suppose the "doc" tag of this issue means exactly this :) )

Regards

I think it would be helpful to mention it directly in the documentation, yes.

@targos

@targos

@targos I tried to make an edit

doc,fs: update description of fs.stat() method
