To use the GRANT ALL permissions for MYSQL 8.0.12

I tried to use GRANT ALL PRIVILEGES without success.

This is the command prompt (with administrator rights):

After I entered the command, I just received the following (Note: I only copy a snippet here)

Enter the code here: Program Files MySQL MySQL Server 8.0 bin> mysql GRANT ALL PRIVILEGES ON , TO & # 39; root & # 39; @ & # 39;% & # 39; WITH GRANT OPTION;
mysql Ver 8.0.12 for Win64 on x86_64 (MySQL Community Server – GPL)

I want to know how to run GRANT All because Windows 10 does not seem to respond to the command.

I can also get most into the bin folder of the MYSQL folder, I can not access the MYSQLAdmin.exe
