Execute windows command in Java

Question

Need to run netstat -n | find ":3389" | find "ESTABLISHED" command using Java Runtime.

Tried like: Runtime.getRuntime().exec(cmd); but we can't do this if we have | (pipe) in our command.

I had found for linux command we can costruct like: String[] cmd = {"/bin/sh", "-c", "grep -c 'Report Process started' /path/to/server.log"}; Runtime.getRuntime().exec(cmd); but I need for windows, please let me know how we can do?

same answer as stackoverflow.com/questions/15464111/… despite I would prefer user1121883's answer — user85421

You should run only netstat -n and do the rest in java. You could also write a script, and execute the script instead of separate commands. If you really need to do everything in a single line that has pipes the command must be prefixed with cmd /C

Ya that works, but checking is there any other way similar to linux. Because that way its looking much cleaner and we can find easily what we are doing.

In Windows we can achieve this like:

String[] cmd = { "cmd.exe", "/c",
                    "netstat -n | find \":3389\" | find \"ESTABLISHED\"" };
Process process = new ProcessBuilder(cmd).start();
