Cannot execute shell script from Java program

Question

I have a java program which runs on Linux and attempts to call one shell script. This shell script tries to copy a local directory to another server. The way to call the script is :

bash copy_logs.sh "TestResults/07232015042652"

When i call this from linux terminal, the directory gets copied to remote server successfully. Now i want to execute this from Java program. My code snippet is as follows :

Sting direc = "07232015042652"
p = Runtime.getRuntime().exec("bash copy_logs.sh \"TestResults/"+direc+"\"");

When i run this, though i do not get any error or exception but the file never gets copied.

Contents of copy_logs.sh is as follows :

scp -r $TS test@192.168.199.57:/home/apacheweb/html/Weekly_Status/prov_check/
if [ $? -eq 0 ]
then
        echo "File copied successfully"
else
echo "Failed to copy"

I tried to print the result of execution by

InputStream is = p.getInputStream();
    StringBuilder sb = new StringBuilder();

    int i=0;
    try {
        while ((i=is.read())!=-1){
            sb.append((char)i);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    System.out.println(sb);

And i get the output : Failed to copy . Just wondering what can be root cause of this???

Answer 1

Got it working by :

 ProcessBuilder pb = new ProcessBuilder("bash", "-c", "/bin/bash copy_logs.sh \"TestResults/"+directoryName+"\"");
 Process shell = pb.start();
