Batch File programming is really really easy then any other programming language.
Actually, it's nothing but a batch of DOS ( Disk Operating System ) commands, hence the name Batch programming .
If you are into coding and know many languages you might have noticed that Operating System ( OS ) specific languages
( languages that work only on a particular operating system, eg: Visual Basic Scripting works only in Windows ) give you amazing control over the system.
This is why Batch is so powerful, it gives you absolute control over DOS.
Batch isn’t often used because it is OS specific, but it is fun and easy to learn.



Introduction To Batch Files



Part 1



Part 2





How to create a batch file
Spoiler:
  1. Open Notepad
  2. Type Whatever you want ( the code you want to enter)
  3. Click : "Save as"
  4. Change the file type to all files and folder
  5. Name the file as anything you want with the extension .bat





Basic CMD Commands
  • echo - This is a way you can insert text into the cmd window.
  • pause - This pauses CMD (This should be used after echo to keep the text on the screen).
  • exit - This exits the CMD window.
  • start - You Can start programs with this (You can put just the name in here if its in the windows folder otherwise you need a directory).
  • del - Deletes files (You May Need a Directory for this).
  • copy - Copies files (You Need 2 Directory's for this the starting 1 and the directory you want the file to end up ).
  • Move - Moves Files (You Need 2 Directory's for this the starting 1 and the directory you want the file to end up ).
  • %random% - Random Numbers (To See Numbers put %random% after echo)
  • Call - Calls another batch file.
  • CLS - Clears the screen of any previous data.
  • BREAK ON/OFF - When turned on within the batch file, the user has an option of stopping the batch file by bressing Ctrl+Break.
  • GOTO - This command is used to go to another section of the batch file
  • End - Ends the process.


Shutdown Command
  • shutdown : Gives the computer the command to either logoff, shutdown,restart or abort a shutdown
  • shutdown
  • shutdown -s
  • shutdown -r
  • restarts
  • shutdown -l

shutdown -r -t 360

The timer dosen't work for logoff.

Too many people get "commands" and "executables" mixed up when it comes to batch. There's a difference, and the number of actually commands for cmd.exe are few and limited.

shutdown is an executable (shutdown.exe exists).
