+Environment variables
+^^^^^^^^^^^^^^^^^^^^^
+
+``sudo`` does not forward environment variables by default. Put the variables before the ``php`` command::
+
+  sudo -u www-data NC_debug=true php occ status
+
+Alternatively, you can ``export`` the variable or use the ``-E`` switch for ``sudo``::
+
+  NC_debug=true sudo -E -u www-data php occ status
