I'm new to use Spring-batch and I'm trying to get an handle of the SystemCommandTasklet function. Files are not getting splitted from the code. split is working fine if executed as unix command

<!-- spring batch core settings -->
<import resource="../config/context.xml" />


<job id="accountingJob" xmlns="http://www.springframework.org/schema/batch">

  <step id="step1" xmlns="http://www.springframework.org/schema/batch">

     <tasklet ref="fileSplittingTasklet" />              

</step>  
</job>

<!-- Jobs to run -->

<bean id="fileSplittingTasklet" class="org.springframework.batch.core.step.tasklet.SystemCommandTasklet" scope="step">
<property name="command" value="split -a 5 -l 4 #{jobParameters['inputFile']} #{jobParameters['stagingDirectory']}"/>
<property name="timeout" value="60000"/>
<property name="workingDirectory" value="/test/temp"/>

invoking code public class App {

public static void main(String[] args) {

    App obj = new App();
    obj.run();

}

private void run() {

    String[] springConfig = { "spring/batch/jobs/job-partitioner.xml" };

    ApplicationContext context = new ClassPathXmlApplicationContext(springConfig);

    JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
    Job job = (Job) context.getBean("accountingJob");

    try {

        //JobParameters param = new JobParametersBuilder().addString("age", "20").toJobParameters();

        JobExecution execution = jobLauncher.run(job, new JobParameters());

        System.out.println("Exit Status : " + execution.getStatus());

        System.out.println("Exit Status : " + execution.getAllFailureExceptions());

    } catch (Exception e) {
        e.printStackTrace();
    }

    System.out.println("Done");

}

}`

getting time out error and no split is happening. Please find below error from console
