কমান্ডগুলি আমাকে কমান্ডের অবস্থানটি পছন্দ করে না whereisবা whichদেখায় না তার কারণগুলি কি? উদাহরণস্বরূপ আমার এনভিএম রয়েছে এবং এটি কোথায় অবস্থিত তা জানতে চাই, তবে এই আদেশের কোনওটিই বাইনারিটি সন্ধান করতে আমাকে সহায়তা করে না। আমার কি কেবল findএই ক্ষেত্রে ব্যবহার করা উচিত ?

nvm। আমার দরকার নেই আমি এটি কোথায় অবস্থিত তা জানতে চাই
@BroSlow আপডেট দয়া করে দেখুন
