The path environment variable saves one path, which can be multiple paths. When we enter a command or access a file on the command line, the system will first look for it in the current directory, and if it finds it, execute it or open it directly. , If not, then go to the path of the path environment variable to find the location until the location is found. If the path is not found, the error is not an internal or external command, nor an executable program or batch file,
so we can add some frequently needed The path of the accessed file or program is added to the path environment variable so that we can access it anywhere,
7. Precautions for PATH environment variable
