Batch commands are text-based scripts written in a sequence, typically saved with a .bat or .cmd file extension. When executed, these scripts run a series of commands automatically. They are essentially a set of instructions to the system to perform various tasks without user intervention.

1. Basics of Batch Files: A batch file is a plain text file that contains a sequence of commands for the system to execute. These files can be created using any text editor and are executed through the Command Prompt in Windows.
2. Command Syntax and Structure: Batch commands follow a specific syntax and structure. They can include built-in system commands, loops, conditional statements, and can even call other batch files or executable programs.

Batch File Commands

Command	Description
call	Calls one batch program from another while allowing the calling program to continue running
echo	Toggles command-echoing on or off
endlocal	Restores environment variables set by a setlocal command
for	Used to run a specified command for each file in a set of files
goto	Jumps to a specific line that is labeled in a batch file
if	Used to perform conditional processing of commands
pause	Suspends processing of the batch file and waits for the user to respond
rem	Used to insert remarks (comments) in a batch file for documentation purposes
setlocal	Initiates localization of environment variables in a batch file
shift	Used to change the position of replaceable parameters in a batch file
