Get actual path symlink is pointing to

Question

Given a symlink, I want to know to which directory this symlink is pointing. Does the Rust standard library offer something to find this out? I have only found unstable API functions so far.

Answer 1

It seems to me that you want fs::read_link:

Reads a symbolic link, returning the file that the link points to.

Answer 2

You can use std::fs::canonicalize:

Returns the canonical, absolute form of a path with all intermediate components normalized and symbolic links resolved.
