he verbose option simply produces verbose output on your screen. it means that the program provides comments on the operation as they occur, so you will see real-time status of what the utility or program is doing to run the tasks or commands you sent

for example you know when you ping, you see the replies as they happen, well, that’s what it means, if you didn’t want to see the verbose, then the system would not show you the replies it got, it would just ping without you knowing. like in unix, in linux, if you dont get an error message, then that means the command work. but with verbose, you see what the command is doing
