Due to my own reasons, I have been at home with my children for the past six months, and I haven’t written a blog for a long time. Recently, I need to copy and copy the part-time work at home. I suddenly became interested and wanted to study batch processing. I feel that it is really convenient to use sometimes.
Create a new text directly, change the suffix to .bat to build a batch program, and then open it with text to write. After searching, I found that iBat is a very good software for editing, very foolish and convenient, and can write batches without command deal with.
Learning objectives: be able to understand Bat files and modify files.
DOS batch command is a scripting language, which is executed line by line according to the top-down process, that is to say, only after the command of the first line is executed, can the second line be executed, and after the second line is executed, Then execute the third line.
[Basic]
echo off //Close the echo, generally written at the beginning of the batch, indicating that only the command result is displayed, and the executed command is not displayed. If @, @echo off is added in front, then this command itself does not display echo on
/ /Contrary to the above
echo. //Followed by a decimal point, display a blank line
echo //Space followed by text, display text
rem //Comment, if the echo is turned on, the content of the comment will be displayed
:: //Comment, complete comment is not Display and echo
cd c:\ //Jump to C drive
/? //After the command, /? will prompt the usage and parameters such as choice/?
>nul //The command is connected at the end, without displaying the result and prompt
pause //Pause, Display please press any key to continue, pause>nul does not display text
ping //followed by IP, display delay
title //window title bar name
color 0A //text green background black
exit //exit batch program, and exit CMD console
cls //clean screen
errorlevel //built-in error level variable 0 No error Other value error
%0 //Script itself
start /max "" "D:\cloudmusic.exe" //Run the program with the largest window
echo text>c:\test.txt (text>>c:\test.exe txt) // Create txt text > If the file exists, it will be overwritten >> If it exists, it will be accumulated and written to
[folder]
md (mkdir) c:\folder//Create folder (..\folder//Create to batch In the upper-level directory where the processing file is located)
ren (rename) c:\folder new name //rename the folder
rd (redir) /s /qc:\folder//delete the folder ( /s delete subdirectories and files /q do not ask)
xcopy /e /yc:\folder D:\folder\ //copy folder (/e copies all subdirectories, including empty directories. /y overwrites files)
copy //copy folder
del //delete file (del 0% delete itself)
【set】
%variable name% //%% is equivalent to a variable reference, such as echo %time% to output the current time
set /p aaa=Please enter a number: //Prompt the user to input and assign the value to aaa
set /a bbb=%aaa% *2 //Execute mathematical operations, bbb is equal to aaa*2
[goto]
goto a //goto jump command a label name specified to jump to the label position and continue to execute the script
: a //Define the label
echo You came with the goto command Label a
goto :eof (the built-in End Of File comes to the last line of the program, which is equivalent to exiting the current Bat script, but it will wait for the next command if it does not exit the CMD console) [if] Note: there is no
else
if
if exists c:\learning.txt (echo exists) ELSE (echo does not exist) //whether exists
if not exists c:\learning.txt (echo does not exist) ELSE (echo exists) //does not exist
[& && || | 】
& Compound statement connector, separating multiple commands in a command line
&& Compound statement connector, the command after && will be executed only when the command before && succeeds.
|| Compound statement connector, when the command before || fails, the command after || will be executed.
The | pipe symbol, the output of the process before | is used as the input of the process after |.
【Delay execution】
1. Because the ping command is executed once a second - n represents the number of times 127.1 is the abbreviation of the loopback address of the local network system 127.0.0.1 > nul does not display the result of ping, so the execution is delayed for 5 seconds
ping 127.1>nul -n 5
2.choice /t Pause for seconds/d The option selected after the time is up/n Hide the option list >nul does not display the result
choice /t 5 /dy /n >nul
