Understanding the Problem: Multiple Status Codes from a Batch File

When working with batch files in Windows, many users face the challenge of capturing the status of commands executed within the script. One common scenario involves running a command that divides a number by several inputs and checking whether each operation was successful. However, it often turns out that the status code represents only the last input processed. This limitation leaves users wanting a more comprehensive solution—one that allows them to track the status of each operation.

The Scenario

Imagine you have a batch file that executes a command to divide 100 by a list of numbers: 5, 0, 10, and 45. You need a method to identify which of those calculations were successful and which failed. Your original approach may have looked something like this:

This, unfortunately, will only provide the result of the last division operation. So, how can you get individual statuses for each input? Let’s dive into the solution.

The Solution: Iterating Through Inputs and Checking Each Status

To retrieve the status codes for each input, you can loop through the numbers individually, execute the command, and check the result. By doing this, you ensure that each operation can be evaluated independently. Here’s how to implement this in your batch file:

Step-by-Step Implementation

Set up your numbers: Create a variable that holds the numbers you want to divide.

Loop through each number: Use a for loop to iterate through each input number, executing the required command.

Check the exit status: After each operation, check the ERRORLEVEL to determine if it succeeded or failed.

Print the results: Based on the outcome of each division, print either "Success" or "Failed".

Example Code

Here is a complete example of how this can be set up in your batch file:

Explanation of the Code

@ echo off: This prevents the commands from being displayed in the command prompt.

set "numbers=5,0,10,45": Defines a variable holding the numbers you want to process.

for %%i in (%numbers%) do: Runs a loop for each number in the numbers variable.

Inside the loop:

The division.exe command executes the operation with the current number (%%i).

The if ERRORLEVEL 1 condition checks if the command failed (an error level of 1 or greater).

Depending on the result, it prints either "Failed." or "Success.".

Conclusion

By using a loop, you can effectively retrieve the status of multiple inputs in a batch file operation. This approach not only enhances the usability of batch scripts but also allows for better error handling and reporting. Now you can confidently execute a command against multiple values and easily track the results for each operation.

Implement this method in your batch files to enjoy a seamless experience when dealing with multiple input statuses!
