How to use BAT batch script

With the popularization of computers and the expansion of application fields, BAT batch scripts are increasingly used in actual work. BAT batch script is a script language running under the Windows operating system. It can complete some common operation tasks through a series of commands. In this article, we will introduce the basic syntax of BAT batch scripts and some common usage scenarios.

1. Basic syntax of BAT batch script

BAT batch script is a text file composed of a series of commands, with .bat or .cmd as the suffix. You can use any text editor, such as Notepad, to write BAT scripts.

The following is a simple BAT batch script example:

@echo off
rem 这是一段注释
echo 欢迎使用BAT批处理脚本！
pause

The first line of the script "@echo off" means to turn off the command echo and not display the executed command itself. This is followed by a comment, starting with "rem". In the BAT script, you can use the echo command to output text information. The pause command on the last line will pause the execution of the script until the user presses any key.

In BAT batch scripts, you can also use advanced syntax such as variables, conditional judgments, and loops to implement more complex operations. Next, we will introduce some common usage scenarios.

2. Commonly used BAT batch script usage scenarios

1. Batch rename files

In daily work, we often need to batch rename files . This requirement can be easily achieved using BAT batch scripts.

Suppose we have a series of image files whose names are not standardized, and we want to change them all into a unified format.

@echo off
setlocal enabledelayedexpansion

set i=1
for %%f in (*.jpg) do (
    set filename=000!i!
    set filename=!filename:~-4!
    ren "%%f" "!filename!.jpg"
    set /a i+=1
)

endlocal

In this script, we use a for loop to traverse all jpg files in the current directory. Set a counter variable i through the set command, and use the enabledelayedexpansion parameter to enable delayed variable expansion. Then, use the ren command to rename the file to a format in which the counter value is the file name, and the counter is incremented by 1 each time the loop is completed.

2. Batch copy files

Sometimes, we need to copy all the files in one folder to another folder. This function can be quickly implemented using BAT batch script.

@echo off
xcopy /s /y "源文件夹路径" "目标文件夹路径"

In this script, we use the xcopy command to batch copy files. The /s parameter means to copy all subdirectories and files in the directory, and the /y parameter means not to prompt the user for confirmation when copying.

3. Automate common operations

BAT batch script can also be used to automate some common operations, such as calling other applications, creating files, deleting files, etc.

The following is a sample script to automatically clean up temporary files and the Recycle Bin on your computer.

@echo off
rem 清理临时文件夹
del /s /q %TEMP%*.*

rem 清空回收站
rd /s /q C:$RECYCLE.BIN
mkdir C:$RECYCLE.BIN

echo 清理完成！
pause

In this script, we use the del command to delete all files in the temporary folder, use the rd command to empty the Recycle Bin, and then use the mkdir command to re-create an empty Recycle Bin.

Summary:

BAT batch script is a simple and powerful tool that can help us automate some repetitive tasks. By mastering the basic syntax and common usage of BAT scripts, we can complete our work more efficiently. I hope this article will be helpful to the use of BAT batch script!
