อะไรคือสาเหตุที่ทำให้คำสั่งเหมือนwhereisหรือwhichไม่แสดงตำแหน่งของคำสั่งให้ฉันดู? เช่นฉันมี NVM และต้องการที่จะรู้ว่ามันอยู่ที่ไหน แต่ไม่มีคำสั่งเหล่านี้ช่วยให้ฉันหาไบนารี ฉันควรใช้เฉพาะfindในกรณีนี้หรือไม่?

nvmมันประเภทแหล่งที่มาของ ฉันไม่ต้องการมัน ฉันต้องการทราบว่ามันอยู่ที่ไหน

หากคำสั่งเป็นนามแฝงคุณสามารถใช้ 'type' <your command> เพื่อตรวจสอบนามแฝง
