How to launch a batch file from an After Effects script?

[jobo3553]

Hello everyone,my Os is Windows 7 EntrepriseI have written this A.E. scriptvar myFile= new File("C:/myBatch.bat");
myFile.execute();When I double clic in my file browser on myBatch.bat, it opens cmd.exe and the batch is correctly executedBUT, if I launch it from an After Effects script as written above, the command window opens and closes at once and nothing happens.The script above works for any kind of applications (.doc, .xls,..) but not with .bat.  WHY?Many thanks,

Hi jobo3553,

Maybe you can try to run the batch script like this,

runBatchScript = function(BAT_PATH) {

  cmd = "cmd.exe /c \"\"" + BAT_PATH + "\" \"";

  return system.callSystem(cmd);

  }

runBatchScript("D:/Desktop/test.bat");

Hi Zhiqing_Li,

Many thanks for your contribution. Unfortunately, it does not work on my system. Does it on yours?

Yes, it works on my computer. The idea is running the bat file from cmd

Hi Zhiqing,

GOOD NEWS. It works now. Even with a slightly simpler script as the one below (on Windows).

runBatchScript = function(BAT_PATH) {

  cmd = "cmd.exe /c " + BAT_PATH ;

  return system.callSystem(cmd);

  }

runBatchScript("D:/Desktop/test.bat");

The reason of the issue I had before was that in my batch I was calling configuration text files or commands using relative path names. It only works when double-clicking on the batch file inside the file explorer but using After Effects scripting it is necessary to refer to command or files inside the batch using ABSOLUTE file path (c:\folder1\folder2\textFile.txt etc.)

Many thanks again for your precious help.

Hi jobo5533,

I have tried the same command suggested by you. But I get error saying that "Unable to access jar file filename.jar ".

my batch file content is

java -jar ./filename.jar ./

I have the filename.jar in the exact same path as the batch file. Do you have any idea?
