Core::ICore::settings()->setValue(“MyPlugin/MySetting”, m_mySetting)

either on IOptionsPage::apply, or at your plugin’s shutdown, or connected to the Core::ICore::saveSettingsRequested() signal (use Core::ICore::instance() as the originating object).

And on your plugin’s startup (e.g. at the time of MyPlugin::initialize()) read the setting again with 

m_mySetting = Core::ICore::settings()->value(“MyPlugin/MySetting”)

The perl script is located in a specific path in my linux machine and there is a parameter passed to it. Currently I am invoking this perl script with the hardcoded path and parameter directly from my plugin. Whenever there is a change in the path or parameter of the perl script, my plugin code also got to be changed.
