Mkdir in Shell Script not creating folder in mac OS while executing using java

Question

cmdFile.sh:

cd "E:\\myWorkSpace\\sampleTest"
mkdir "E:\\myWorkSpace\\sampleTest\output"

Java:

runtime.exec("cmdFile.sh");

The above shell script creates the folder if executed through a command prompt. But, if it is executed using Java, then the folder is not created.

Here you have an example how to run external programm with reading error and outputstream, so you can see if you get an error while running ` cmdFile.sh` — Jens

runtime.exec actually executes a process. Did you mark cmdFile.sh as an executable? Otherwise you should run the following in your terminal first:

chmod +x cmdFile.sh

Otherwise you should call a shell with cmdFile.sh as argument, for instance:

runtime.exec("/bin/bash cmdFile.sh");

On a sidenote, you can write te script in Java as well (so you don't need to start an additional process):

File f = new File("E:\\myWorkSpace\\sampleTest\\output");
boolean wasSuccessfull = f.mkdir(); //or mkdirs if there are more possible nonexisting parent-folders.
