I tested these changes with following program:

package execenv;

public class ExecEnv {
    public static void main(String[] args) throws Exception {
        System.out.println("Env: " + System.getenv("PATH"));
        var p = new ProcessBuilder("netbeans", "S:\\readme.txt").start();
        var r = p.waitFor();
        System.out.println("Res: " + r);
    }
}

when executed on NetBeans 27 it fails with:

With changes in this PR it properly opens the file in the IDE executing the script. Setting NETBEANS_USERDIR=IGNORE opts-out and falls back to previous behavior.

</api></li>

<p>
When the <code>netbeans</code> launcher starts, it also manipulates
(reads and writes) following properties:
</p>
<ul>
<li><api name="NETBEANS_USERDIR" category="devel" group="property" type="export">
<p>
If this <em>environment variable</em> is set to a valid value,
then its value is used as default user dir
instead of <code>netbeans_default_userdir</code> read from
the config file.
</p>
<p>
When the value of user dir is finally determined by the launcher
(by considering default values, value of this environment variable
and <code>--userdir</code> CLI switch, etc.) the launcher sets
<code>NETBEANS_USERDIR</code> environment variable for itself
and its subprocesses.
</p>
<p>
That way executing <code>netbeans</code> in the NetBeans internal
terminal will know what's the userdir of the surrouding NetBeans
and will open files in the same instance just as
<a href="https://github.com/apache/netbeans/pull/8756">#8756 illustrates</a>.
</p>
<p>
The launcher also modifies the <code>PATH</code> variable
by appending its own diretory - making sure typing <code>netbeans</code>
gets handled in the internal NetBeans terminal at all.
In the unusual and rare cases when <b>opt-out</b> of this
behavior maybe needed, just
set the environment variable to <code>IGNORE</code> to instruct
the launcher to avoid these environment variable modifications.
</p>
</api>
</li>
</ul>
</answer>
