Calling an external program from a batch file;

this program may either run successfully or fail;

if it succeeds, it will probably return to the original batch file in about 2 seconds and continue with the next command;

if it fails, it will take more than 10 seconds to return to the original batch file;

since this is executed in a loop, the execution efficiency becomes very low;

I want to know how to forcibly terminate a program that failed to execute, and directly execute the command below;

that is, only allow the program 3 seconds to run;

if it succeeds, then it will definitely succeed within 3 seconds; and the command below will also be executed;

if it fails, then as soon as 3 seconds are up it will forcibly terminate itself and go execute the command below; I don't know whether this can be done;



Can a batch file execute in parallel?


For example

batch file
|
|
program
|
|
program
|
|
program
|
.
.
.

Can it be made to do this

batch file
|

A batch file can only use the "start command" method to open new windows and run multiple commands at the same time; it cannot execute in parallel internally

You can try it like this
start command
check process static
check process static
check process static
Each time you start a program, check its status three times. If it is not responding even once, then kill it. If not, then start the next one

Mm; yes; I found that out myself too.

Isn't check not an internal command? How can you tell that it is not responding? Please advise?

...I was just giving an example, there is no such command

For example, the following
tasklist /fi "imagename eq %1" /fi "status ne running"&&taskkill /f "imagenmae eq %1"

. batch file

| | | | .....
| | | |
a.exe b.exe c.exe

My PS skills are poor, can it be understood as:

start a.exe
tasklist /fi "a.exe eq %1" /fi "status ne running"&&taskkill /f "a.exe eq %1"
start b.exe
tasklist /fi "b.exe eq %1" /fi "status ne running"&&taskkill /f "b.exe eq %1"
......

Something like that

This is what I mean

start a.exe&&set exefile=%exefile%;"a.exe"
call :chkeck
start b.exe&&set exefile=%exefile%;"b.exe"
call :chkeck
...

:chkeck
for /f "delims=;" %%i in ("%exefile%") do (
taskkill /f /im %%i /fi "status ne running"
)
