How do I handle "if errorlevel" in a Windows 10 batch file?

"How can I manage if errorlevel in a Windows 10 batch file?"

To manage if errorlevel in a Windows 10 batch file, you use it to check the exit code of a previously executed command and take action based on that code. Here's an overview of the steps to handle if errorlevel:

Steps to Manage if errorlevel in a Batch File: Understand Error Levels: Error levels are numerical values that indicate the outcome of a command. An error level of 0 typically means success, while any other value indicates an error or different status.

Check for Error Level:

Use the if errorlevel command followed by a number to check for a specific error level. Note that if errorlevel checks for "greater than or equal to" the specified number. For example, if errorlevel 1 means "if the error level is 1 or higher."

Conditional Actions:

Based on the error level, you can perform different actions. This might include displaying messages, executing other commands, or setting variables.

Order Matters:

Since if errorlevel checks for "greater than or equal to," the order in which you write your checks matters. Start with the highest value you want to check and work down to the lowest.

Summary: Understand Error Levels: Error levels indicate the outcome of commands.

Use if errorlevel: Check for specific error levels using if errorlevel.

Perform Actions: Execute actions based on the error level.

Order of Checks: Write checks from highest to lowest value.

By following these steps, you can effectively manage if errorlevel in your batch file and handle different command outcomes.
