Shell script to find files with similar names -


मेरे पास एक फाइल है जिसमें कई फाइल हैं: 

  file001_a file002_a file002_b file003_a

एक खोल स्क्रिप्ट का उपयोग करके, मैं सोच रहा था कि इस निर्देशिका में सभी फाइलों को सूचीबद्ध करने के लिए सबसे आसान तरीका होगा जो पहले 7 अक्षरों में डुप्लिकेट है; यानी उपरोक्त उत्पादन होगा: 

  file002_a file002_b

कोई भी मदद बहुत सराहना की जाएगी! 

  एलएस -1 * _ * | (I) में प्रिंट I, a [i]} '' [एफएन = सबस्ट्रैक्ट ($ 0,1,7); एक [एफएन] = एक [एफएन] "सबस्ट्रैक्ट ($ 0,8)}" / कोड>

But I do not think the code is capable of changing the color of each variable declared....
