Windows Command Prompt (CMD. EXE) is a shell program under Windows NT to run Windows control panel programs or some DOS programs, or under Windows CE only to run control panel programs. CMD instructions have a lot of use is also very wide!
Here are some more advanced instructions for those of you who have some basic knowledge of computers or have studied them in greater depth.
Such as disk, directory, File Operation Code. Disk, fdisk implied, parameter/MBR rebuilds master boot record fdisk/MBR rebuilds master boot record
After DOS7.0, fdisk added the/CMBR parameter to rebuild the master boot record of the underlying hard disk when mounting multiple physical hard disks, such as fdisk/CMBR 2, which overrides the master boot record of the second hard disk. Be very careful when using it to avoid damaging the good hard disk boot record
Format parameter:/Q Quick Format/U unrecoverable/autotest not prompted/S create MS-DOS boot disk format C:/Q/u/autotest
Table of contents,
[/s ][/w ][/p ][/a ] lists directories, parameters:/s looks for subdirectories/W only shows file name/P page/a shows hidden file formatdir. EXE/s finds the format of the disk. EXE file and report the location

CD (Chdir)[ directory name ] PS: you can use a relative or absolute directory to go to the Directory CD AA to go to the AA directory under the current folder, CD:. Go to the previous folder CD returns to the root directory; CD C: Windows goes to the C: Windows Folder
RD (RMDIR)[ Directory name ] delete directory RD Helloworld Delete Helloworld Directory

delete directory and its files: RMDIR [ directory name or file name ][/s ][/w ][/p ][/a ]. Example RMDIR C: qqdownloads delete the QQDOWNLOAD Directory of the C disk.

Attribub [ parameter ][ source or directory ] file properties Operation Command, attribub command can list or modify the properties of a file on disk, including document (a) , read-only (R) , hidden (h) , system (S) , such as: b-h-r-s io. When SYS executes this command, it will send the DOS system file IO. SYS file read-only, hidden, system properties removed, this will be directly through the DIR command to see Io. SYS file. This is an application that can be applied to an application like this. Bat adds the above attributes to an automatic batch file.

Wait for the command.
We can take a CMD command shutdown to demonstrate it. Open CMD, type shutdown. If you want shutdown to type shutdown-s, restart shutdown-r to shut down, you can type shutdown-s-t XXX. XXX means how many seconds to shut down for a minute and 60 seconds, and then you can type shutdown-s-t 60, depending on the situation. If you do not bother to open the CMD input instructions can be made a XXX. BAT file. Method: Open Notepad input shutdown or restart the timing shutdown (depending on the user) code, SAVE, file name can edit itself but the suffix name must be changed to bat file.
CMD instructions for certain people have a lot of use, must not be used for illegal purposes.
