A BAT file for switching the AAA.exe file on or off.

Make a BAT file to open or close the AAA.exe file.

First use tlist to judge whether there is the AAA.exe file in the process.

If there is no this process, then it is necessary to open this process.

If there is this process, then it is necessary to kill this process. How to implement?

I used if, but I don't know how to judge whether there is this process in memory.

Can everyone give me some ideas?

tasklist|find "QQ.exe" > 1.txt
type 1.txt|find "QQ.exe" && taskkill /f /im qq.exe || start D:\Tencent\QQ\qq.exe
del 1.txt

Replace "qq.exe" with your program.

关于 fan927 的回复：

可以考虑合并为一句：

tasklist|find "QQ.exe">nul && taskkill /f /im qq.exe || start D:\Tencent\QQ\qq.exe

About fan927:

It can be considered to combine into one sentence:

tasklist|find "QQ.exe">nul && taskkill /f /im qq.exe || start D:\Tencent\QQ\qq.exe

Yes, it's indeed adding unnecessary details.

```

If I use it like this:
:A
tasklist|find "QQ.exe" || shutdown -l -f -t 10 (Log off if this program doesn't exist)
???? (If this program exists, delay for 5 minutes and then return to :A. How to write this)
```

A:
tasklist|find "QQ.exe" &&ping 1.1.1.1 -n 1 -l 1 -w 300000&&goto A|| shutdown -l -f -t 10

\\ If tasklist|find "QQ.exe" is successful, then ping the unreachable IP 1.1.1.1 to delay. After the delay is completed, return to A:
ping 1.1.1.1 -n 1 -l 1 -w 300000, I have tested with a packet capture tool, and within 300 seconds, only one 64-byte ICMP packet will be generated, and the impact on the network can be ignored.

How to implement it with the 2000 system?

How to make a loop command to determine whether a program exists in memory and then make a choice to delete it?

tasklist|find "QQ.exe“ && ping 1.1.1. What are the functions of the "&&" and "||" here: In batch scripting, "&&" is a logical operator. The command before "&&" will be executed first. If that command executes successfully (returns a exit code of 0), then the command after "&&" will be executed. "||" is also a logical operator. The command before "||" will be executed first. If that command fails (returns a non-zero exit code), then the command after "||" will be executed.

For the issue of not hiding the content: To completely hide the output, you can redirect the output. Modify the line with the ping command to something like ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul. The ">nul" redirects the standard output to null and "2>nul" redirects the standard error output to null. So the modified line would be ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul&&goto A|| shutdown -l -f -t 10受教了……谢谢楼上的大虾，有两个问题：
1、延时300000后面的"&&"和"||"这2个符号各是什么作用？
2、如果想这个带有PING命令的批处理文件在命令行窗口不显示内容，加上@echo off 后怎么还是不行啊？显示ping 1.1.1.1…… 怎么解决？谢谢……
The functions of "&&" and "||" in batch scripting: "&&" means that if the preceding command executes successfully (exit code 0), then the following command will be executed. "||" means that if the preceding command fails (non-zero exit code), then the following command will be executed.

For the issue of not hiding the output: To make the ping command's output not display, you can redirect the standard output and standard error. Modify the ping command line to ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul, so the line becomes ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul&&goto A|| shutdown -l -f -t 10
### Translation
tasklist|find "QQ.exe“ &&ping 1.1.1.1 -n 1 -l 1 -w 300000&&goto A|| shutdown -l -f -t 10
Got it... Thank you, senior. There are two questions:
1. What are the functions of the two symbols "&&" and "||" after the delay of 300000?
2. If you want this batch file with the PING command to not display content in the command line window, why does it still not work after adding @echo off? It shows ping 1.1.1.1…… How to solve it? Thank you……

In batch scripting, the role of "&&": If the previous command executes successfully (exit code 0), then the subsequent command will be executed. The role of "||": If the previous command fails (non-zero exit code), then the subsequent command will be executed.

For the issue of not hiding the content: To completely hide the output, you can redirect the output. Modify the line with the ping command to something like ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul. The ">nul" redirects the standard output to null, and "2>nul" redirects the standard error output to null. So the modified line would be ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul&&goto A|| shutdown -l -f -t 10
tasklist|find "QQ.exe“ && ping 1.1.1.1 -n 1 -l 1 -w 300000&& goto A|| shutdown -l -f -t 10

In batch scripting, for "&&": If the preceding command executes successfully (exit code 0), the following command is executed. For "||": If the preceding command fails (non-zero exit code), the following command is executed.

For the issue of not hiding the output: To make the ping command's output not display, you can redirect the standard output and standard error. Modify the ping command line to ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul, so the line becomes ping 1.1.1.1 -n 1 -l 1 -w 300000 >nul 2>nul&& goto A|| shutdown -l -f -t 10
