How to install onto external hard drive Mac Already have terminal codes

Am I supposed to replace something with my external hard drive name? Here are codes Sudo mv /Users/Shared/UnrealEngine /Destination/Location/ and ln -s /Destination/Location/Shared /Users/Shared/UnrealEngine

My hard drive name is HARD_DRIVE so if you could type code with my hard drive’s name, that would be great. Thanks!
