pub fn real_home_dir() -> Option<PathBuf>Expand description
Get the real user’s home directory, accounting for sudo scenarios.
When running under sudo, dirs::home_dir() returns root’s home directory
because $HOME is set to /root. This function checks for SUDO_USER and
attempts to use that information.
Note: This crate forbids unsafe code, so we cannot use getpwnam_r. Instead, we use environment variables and construct the path.
