Thanks for helping. Code below is working now.
public class InteractiveExecCmd {
public static void main(String[] args) throws Exception {
SshClient client = SshClient.setUpDefaultClient();
client.start();
String hostname = "<hostIP>";
String password = "<pwd>";
ConnectFuture cf = client.connect("root", hostname, 22);
ClientSession clientSession = cf.verify().getSession();
clientSession.addPasswordIdentity(password);
clientSession.auth().verify(TimeUnit.SECONDS.toMillis(10));
ChannelExec ce;
try {
ce = clientSession.createExecChannel("bc");
OpenFuture openFuture = ce.open().verify(30, TimeUnit.SECONDS);
Stack<String> cmds = new Stack<>();
cmds.add("`");
cmds.add("723+323");
cmds.add("734334*23343434");
// Create a new thread to handle input
OutputStream stdin = ce.getInvertedIn();
Thread t1 = new Thread(() -> {
// Code to be executed in the new thread
try {
while (!cmds.empty()) {
String cmd = cmds.pop();
stdin.write((cmd + "\n").getBytes());
stdin.flush(); // Flush the input to ensure it's sent
System.out.println("Sent: " + cmd);
}
stdin.write("quit\n".getBytes()); // Exit the bc session
when done
stdin.flush();
} catch (IOException e) {
throw new RuntimeException(e);
}
});
t1.start();
// Capture and print the output from bc
InputStream outputStream = ce.getInvertedOut();
InputStream errorStream = ce.getInvertedErr();
BufferedReader reader = new BufferedReader(new
InputStreamReader(outputStream));
String line;
if (outputStream != null) {
// Read output from bc
while ((line = reader.readLine()) != null) {
System.out.println("bc output: " + line);
}
}
if (errorStream != null) {
BufferedReader errorReader = new BufferedReader(new
InputStreamReader(errorStream));
// Read error from bc
while ((line = errorReader.readLine()) != null) {
System.out.println("bc error: " + line);
}
}
Set<ClientChannelEvent> events =
ce.waitFor(EnumSet.of(ClientChannelEvent.CLOSED),
TimeUnit.SECONDS.toMillis(2));
t1.join();
} catch (IOException e) {
throw new SshClientException("Failed to execute command", e);
} finally {
try {
clientSession.close();
} catch (IOException e) {
System.out.println("Got exception while closing session");
e.printStackTrace();
}
}
}
}
