Question

I have a while loop which appends data in a while loop and it closes every time before the end of the loop. Is it possible to sync that file to a server after I close the file and before I end the loop?

//--- Pseudocode
while(1){
    writer.append(data1);
    writer.append(,);
    writer.append(data2);
    writer.append(,);
    writer.flush(),
    // --I need to run a command here that lets me sync the file to the server
}

Im trying to Runtime.exe() after the flush. Will that be a good idea? Will it cause any delay?

If I understand your question correctly, you should just use ProcessBuilder.

ProcessBuilder pb = new ProcessBuilder("scp", yourfileName, "[e-mail]:/remote/folder");
Process p = pb.start();

But I have not tested this code.

You may run into problems, such as:

• If you are using a password (and not a public key) to authenticate, I don’t know if scp accepts a password from standard input.
