Это одно из простых решений ES5, о которых я мог подумать -
function duplicates(arr) {
var duplicatesArr = [],
uniqueObj = {};
for (var i = 0; i < arr.length; i++) {
if( uniqueObj.hasOwnProperty(arr[i]) && duplicatesArr.indexOf( arr[i] ) === -1) {
duplicatesArr.push( arr[i] );
}
else {
uniqueObj[ arr[i] ] = true;
}
}
return duplicatesArr;
}
/* Input Arr: [1,1,2,2,2,1,3,4,5,3] */
/* OutPut Arr: [1,2,3] */
Я понимаю, что это старая тема, но я боролся с подобной проблемой сегодня. Это мое решение.
public class ChannelConsole {

ChannelExec channel = (ChannelExec) this.session.openChannel("exec");
channel.setCommand(command);
ByteArrayOutputStream responseStream = new ByteArrayOutputStream();
channel.setOutputStream(responseStream);
channel.connect();
try {
awaitChannelClosure(channel);
} catch (InterruptedException e) {
// no one cares
}
String result = responseStream.toString();
closeQuietly(responseStream);
return result;
}
// ================================================

// ================================================
private void awaitChannelClosure(ChannelExec channel) throws InterruptedException {
while (channel.isConnected()) {
Thread.sleep(100);
}
}
private static void closeQuietly(Closeable closeable) {
if (closeable == null) {
return;
}
try {
closeable.close();
} catch (IOException ignored) {
ignored.printStackTrace();
}
}
}
Используя этот класс, вы можете просто сделать что-то вроде: shell = new ChannelConsole(this.session);
String result = shell.execute("quota -v; echo; echo \"Disk storage information:\"; df -hk")
Попробуйте это:
JSch jsch = new JSch();
try
{
Session session = jsch.getSession("root", "192.168.0.1", 22);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
String command = "lsof -i :80";
Channel channel = session.openChannel("exec");
((ChannelExec) channel).setCommand(command);
channel.setInputStream(null);
((ChannelExec) channel).setErrStream(System.err);
InputStream in = channel.getInputStream();
channel.connect();
byte[] tmp = new byte[1024];
while (true)
{
while (in.available() > 0)
{
int i = in.read(tmp, 0, 1024);
if (i < 0)
break;
System.out.print(new String(tmp, 0, i));
}
if (channel.isClosed())
{
System.out.println("exit-status: " + channel.getExitStatus());
break;
}
try
{
Thread.sleep(1000);
}
catch (Exception ee)
{
}
}
channel.disconnect();
session.disconnect();
}
catch (Exception e)
{
System.out.println(e.getMessage());
}
