#Batch is a scripting language that executes a series of commands in the Windows operating system. It can automate repetitive tasks, including file operations. In this article, we will explore how to use batch scripts to modify file names in batches.

A batch script is a text file that contains a series of commands. They can be created using Notepad or other text editor and saved with a .bat file extension. The following is a simple batch script example:

@echo off
setlocal enabledelayedexpansion
set "search=oldname"
set "replace=newname"
for %%f in (*.txt) do (
set "filename=%%~nf"
set "newfilename=!filename:%search%=%replace%!"
ren "%%f" "!newfilename!.txt"
)
echo File names have been modified successfully.
pause

The batch script in the above example is used to replace "oldname" with "newname" in the file names of all .txt files in the current directory. Let’s explain step by step how this script works:

- `@echo off`: This command is used to turn off command echo in the Command Prompt window so that the command itself is not displayed while executing the script.

- `setlocal enabledelayeexpansion`: This command enables delayed variable expansion. This way, we can use the dynamic value of the variable in the loop.

- `set "search=oldname"` and `set "replace=newname"`: These two commands are used to set the strings to be searched and replaced.

- `for %%f in (*.txt) do`: This command is used to traverse all .txt files in the current directory.

- `set "filename=%%~nf"`: This command is used to get the file name (excluding extension).

- `set "newfilename=!filename:%search%=%replace%!"`: This command is used to replace the search string with the replacement string.

- `ren "%%f" "!newfilename!.txt"`: This command is used to rename files.

- `echo File names have been modified successfully.`: This command is used to display the message that the modification was successful.

- `pause`: This command is used to pause the execution of the script in order to view the output results.

To use a batch script to batch modify file names, just follow these steps:

1. Open Notepad or other text editor.

2. Copy and paste the above example script into a text editor.

3. Replace "oldname" with the string you want to search for.

4. Replace "newname" with the string to be replaced.

5. Save the file as a .bat file (for example, modify_filenames.bat).

6. Double-click the .bat file to execute the script.

Please note that the functionality of the batch script can be modified as needed. For example, you can change file extensions, search and replace strings, or modify file filters in loops.

To sum up, batch scripting is a powerful tool that can help us automate repetitive file operation tasks. By using batch scripts, we can easily modify file names in batches and improve work efficiency. .
