लंबी हार और लगभग भूल गए।
कोड आदि को री-फैक्टर करने का मतलब है, लेकिन पोस्ट इस प्रकार है। इस कोड का उपयोग 32-बिट सिस्टम पर किया जाता है। यह निश्चित नहीं है कि यह 64-बिट (या अन्य) पर कैसे व्यवहार करेगा।
सी-कोड में कहीं भी हैक किया है, (PID को निकालते हुए)।
इसे हैक और ट्विक करने के लिए किसी भी पोस्ट के रूप में छोड़ दें। एक संपूर्ण के रूप में मेरी वर्तमान स्क्रिप्ट ( pidविकल्प के रूप में इसका उपयोग किसी भी GUI पर काम करना चाहिए, यह "GUI-PID / कार्यक्रम" और इसके उपयोग के रूप में है wmctrl -l -p):
