ऐसे कौन से कारण हैं जिनकी वजह से मुझे कमांड का स्थान पसंद है whereisया whichनहीं दिखता है? जैसे मेरे पास एनवीएम है और यह जानना चाहता है कि यह कहां स्थित है, लेकिन इनमें से कोई भी कमांड मुझे बाइनरी खोजने में मदद नहीं करता है। क्या मुझे केवल findइस मामले में उपयोग करना चाहिए ?

यदि कमांड एक उपनाम है तो आप उपनाम की जांच करने के लिए 'टाइप' <अपनी कमांड> का उपयोग कर सकते हैं।
