     2. `$2`: The working directory (might differ from `$PWD` in case of symlinked paths; non-canonical).
     3. `$3`: The picker mode output file (`-` for stdout) if `nnn` is executed as a file picker.
 - Sets the environment variable `NNN_PIPE` used to control `nnn` active directory.
+- Exports the [special variables](https://github.com/jarun/nnn/wiki/Concepts#special-variables).
 
 Plugins can also read the `.selection` file in the config directory.
