Basics of Batch Scripting

Prerequisites for batch scripting are minimal; CMT is by default available for Windows operating systems. Edit scripts with Visual Studio Code or Notepad, and install the batch extension.

Learn how to display messages on the console using the echo command, including strings and numbers, and how to hide commands with @echo off to show only the output.

Define variables with set in batch scripting, assign strings or numbers, and display with echo using %variable%; avoid treating variables as commands unless explicitly invoked.

Explore environment variables in batch scripting by using set to display variables and values, reference predefined variables like the system root variable, and switch directories to list files.

Declare a sum as 10+10 using /A, then display the computed result in batch scripting. Explore arithmetic, logical, and bitwise operators, and view command details with /?.

Learn to capture user input in batch scripting by displaying prompts, storing responses in variables, and performing simple arithmetic with two numbers to display a result.

Learn how batch scripting uses command arguments as input data, with examples like passing your name and listing C:\Windows directories, and displaying the volume serial number.

Define and call functions in batch scripting using labels, group multiple functions, and manage control flow with goto to avoid looping issues.

Master batch scripting by applying functions with goto and exit to control flow, call and display functions, and exit the current batch without closing the entire session.

Learn to implement local scope in batch scripting by using local declarations to keep variables like name and number confined to a block, preventing them from becoming global.

Master the batch scripting if statement by defining conditions with operators such as equals, not equal, less than, and greater than; use variables and conditional execution.

Learn how the else statement runs when an if condition is not true in batch scripting, handling wrong paths and displaying messages.

Learn to use a for loop in batch scripting to generate a range from zero with one-step increments, ending at a limit, and print each value to the console.

Discover how to use errorlevel in batch scripting to detect command success (zero) or failure (nonzero), handle user input, and branch logic with if statements.

Learn to redirect command output to a log file in batch scripting using > to create or overwrite and >> to append outputs to a single file.
