java how to call external unix command

Question

I would like to call a unix system command in java code, I write code like this:

String cmd = "split -a -d -b 10M test.txt";

Process execProc = Runtime.getRuntime().exec(cmd);

I hope when the external command is finished, I could continue to execute the following program. How to implement it?

Try

execProc.waitFor();

This should block until the command is finished. Also maybe you should consider using ProcessBuilder, it offers much more convenient API for handling processes.

ProcessBuilder builder = new ProcessBuilder(command);
Process process = builder.start();
process.waitFor();
InputStream stream = process.getInputStream();
