[batch dos-cmd command - summary and summary] - application startup and call, service and process operation commands (start, call, and)

One 、 Program startup command ——start

start Command is usually used to open a file （ It is usually an executable program ） Or folder .

First use start /? Command for general help information .

（1） Open a folder .start dir, This dir It can be the root directory of the disk , It can also be a subdirectory on the disk . If not min or max Parameters , It will be maximized by default （ Open at the front desk ）.

If you want to open e Packing list , Carry out orders 【start e:】.

  If you want to open e A folder under the root directory （ for example adobe）, Carry out orders 【start e:\adobe】

 

（2） Open a file . start path, This path It can be a document type txt、doc、excel file , It can also be multimedia mp3、mp4 file , It can also be executable exe、bat file .

Try opening it exe file ,【start D:\ Summary of green installation free small software \PdgCntEditor_PDF Directory editor \PdgCntEditor.exe】.

Successfully opened .

（3） Whether it's opening a file , Or open the folder , Pay attention to the problem of spaces .

What do you mean ？ What do you mean by paying attention to blank space ？

cmd Spaces are often used to distinguish between different parameters in the window , If you use a space, it often means that the next parameter is after the space or the value of the parameter before the space is given .

  For example, the path of cool dog music is 【D:\Program Files (x86)\KuGou\KGMusic\KuGou.exe】, Then we execute the order 【start D:\Program Files (x86)\KuGou\KGMusic\KuGou.exe】, You'll find something wrong . Prompt file not found （ clip ）【D:\Program】, It's easy to know cmd The program separates the path string before and after the space , How can we solve this problem ？

The solution is simple , Which level directory has a space in its name , Just put double quotation marks there . Carry out orders 【start D:\"Program Files (x86)"\KuGou\KGMusic\KuGou.exe】.

Note that the command is not executed 【start "D:\Program Files (x86)\KuGou\KGMusic\KuGou.exe"】 , I don't know why , Visually reflect , Will reopen a cmd window , Working directory unchanged .

  If there are multiple spaces on the full path , It is obviously troublesome to add double quotation marks to each level .

In fact, we have another way .

Suppose you want to open a folder 【D:\BaiduNetdiskDownload\test1 2 3\test 3 4 5】, Carry out orders 【start "" "D:\BaiduNetdiskDownload\test1 2 3\test 3 4 5"】（ Fill in the first double quotation mark ）.

（4） If you do not want the window to appear on the screen immediately after executing the command , That is, you want to open it in the background , It can be used /min Parameters .

For example, open a exe Program , Carry out orders 【start /min D:\ Summary of green installation free small software \PdgCntEditor_PDF Directory editor \PdgCntEditor.exe】

Sure enough, it was opened in the backstage . 

But I still found some programs , Even if you add /min Parameters ,

Can't open in the background , Like cool dog music .

Two 、 Program call command ——call

Call The purpose of the command is to call what has been written bat file , Suppose it is called bat File name is 【demo.bat】, Actively invoked bat The file name is 【main.bat】, So in main.bat Call in demo.bat It needs to be used call command .

similar C Function declaration in language , Function defined in demo.bat In the middle of , The function is declared in the main program file main.bat In the middle of .

Print first call Command help information .

Let's see how to use it call This command .

Create a new one demo.bat file , The code inside is .

@echo off
echo  Now start executing the subroutine 
echo  You can count to 10 Do you ？
echo  I can't help it ！ 1,2,3,4,5,6,7,8,9,10
echo  That's great 
echo  I wish you happiness 
echo  See the ghost 
echo  Why didn't you do anything later 
echo  See the ghost 
echo  Go on ？

Let's create another one main.bat file , The code inside is .

chcp 65001
@echo off
echo  Hey, Lao tie has got it ！ The main program starts to run ...
echo  Can you count ？
echo  I'm not going to , But my son will , You ask him .
call D:\D-desktop\demo.bat
echo  The main program is over , Have a good rest .
pause

  Visible direct use 【call path】 You can successfully call .

But I still found some problems during the experiment .

The first question is ： Suppose the last line of the subroutine file has pause, Will bring you closer pause The end of a period in a few lines of 、 Or the line at the end of the question mark should be treated as an order , It turns out to be wrong .

For example demo.bat File modification , and main.bat The document remains the same .

@echo off
echo  Now start executing the subroutine 
echo  You can count to 10 Do you ？
echo  I can't help it ！ 1,2,3,4,5,6,7,8,9,10
echo  That's great 
echo  I wish you happiness .
echo  See the ghost .
echo  Why didn't you do anything later .
echo  See the ghost .
echo  Go on ？
pause

After execution pause Before 4 There are problems in all the lines . 

  The second question is ： Suppose I remove the last line of the subroutine file pause, Then, the last few lines of commands will fail .

Same will demo.bat The document is modified , then main.bat remain unchanged .

@echo off
echo  Now start executing the subroutine 
echo  You can count to 10 Do you ？
echo  I can't help it ！1,2,3,4,5,6,7,8,9,10
echo  That's great 
echo  I wish you happiness 
echo  See the ghost 
echo  Why didn't you do anything later 
echo  See the ghost 
echo  Go on 

The execution result is shown in the figure below , Last 4 OK, and the whole army was destroyed . Don't think it's just the end 4 That's why things go wrong , You can try it yourself , A lot of bug, Therefore, it is recommended to use this function with caution , You can put the code in the main program .

3、 ... and 、 process / Service operation ——tasklist、net

3.1  Process management

• Displays the currently running process ：tasklist
• Run a program or command ：start The program name
• The end of the process , By name ：taskkill /im notepad.exe（ Close Notepad ）
• The end of the process , Press PID：taskkill /pid 1234（ close PID by 1234 The process of ）

3.2 Service management

• Displays the currently running services ：net start
• Start the specified service ：net start service name
• Stop the specified service ：net stop service name
