How to use batch processing to run the latest executable file in a directory? Ignoring subdirectories, without using third-party tools, and the file names have no pattern, ^_^ Let's see how everyone implements it

^_^
dir /o:d is correct or dir /o/d

　　The effect is the same, just try it and you'll know.

^_^What if there are spaces in the file name... What will happen?

D:\Documents and Settings\Administrator>%name%
'd' is not an internal or external command, nor is it a runnable program
or batch file.

D:\Documents and Settings\Administrator>

for /f "delims=" %%a in ('dir /od/b *.exe') do set name="%%a"
"%name%"
Adding quotes, if there are spaces in the file name, it shouldn't go wrong, right

^_^ Think of a problem. If you put this batch file into the directory of the executable program to be run, then this batch file will become the latest file in the directory. This should cause an infinite loop.

for /f "delims=" %%a in ('dir /od/b *.exe') do set name="%%a"
%name%
path %name%
start %name%
This might also work, but I haven't tried it.

　　Re yishanju：
　　
　　It should not cause an infinite loop because this batch file searches only for executable files (*.exe), not batch files (*.bat, *.cmd), so what is executed after running cannot be the batch file;

　　Adding quotes is necessary to prevent errors when running the executable file due to spaces in the executable file name. I overlooked this.

It should not cause an infinite loop because this batch processing only searches for executable files (*.exe), not batch files (*.bat, *.cmd), so what is executed after running cannot be a batch process; ^_^ Well, I removed the .exe when I was thinking about it

for /f "delims=" %%a in ('dir /od/b *.exe') do set name="%%a"
start "f:\tem%name%"
It should be added with start like this. Otherwise, the code below may not execute.

The LZ seems to be going to implement intelligent judgment of the latest executable file in the directory.

It's quite interesting. I'll study it when I have time. The early ideas:

Output file information to log.txt (information collection)
Then import log.txt for judgment (which file is the latest executable file) and then execute

I don't know if the idea is correct.

dir /t:c /o:d Sort by creation time
dir /t:a /o:d Sort by access time
dir /t:w /o:d Sort by modification time
Good method of lxmxn, I didn't notice it before
