How to pause output in command prompt

I have 10 sentence for instance, i want to display one sentence each time i press enter. Does anyone know how to do it in java?(command prompt)

1. Wrap the default System.err and System.out in your own PrintStreams
2. Replace them with your wrapper classes (see System.setErr(PrintStream) etc)
3. In the wrapper classes, parse output looking for '\n' chars + any time you find one, write to that point, then read a return from System.in

How to Get Input from Command Prompt?

How can i get input from command prompt like
C:\
or linux ?
(Here's what I use now)
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String line;
Whlie((line=in.readLine())!= null)
{ System.out.prinln( line) ; }
IS THERE A BETTER WAY?

The main method within a java class accepts command line input through a String array.
In this example args is the String array. You can access the parameters as args[0] for the first parameter, args[1] for the second parameter, etc....
The usage for the example below would be :
c:\EDIFormat file1 file2
Where args[0] would equal file1 and args[1] would equal file2.
public class EDIFormat {
public static void main(String[] args) {
          if (args.length < 0) {
               System.out.println("No Parameters supplied. Exiting....");
               // open input and output files
               EDIFiles(args[0], args[1]);
Hope that helps!

Output to command prompt

I need to limit output of a string of undefined length and undefined number of lines
eg. "a \n b \n c \n d \n e \n f \n g \n..."
to the size of the command prompt default (25 lines?). So I need to take a string, output the first 25 lines without knowing what makes up those lines, then prompt for the user to hit enter before outputting the next 25 lines. Any ideas? /ways to tell how many lines in the console a buffered string will take to output?

How to compile & run using command prompt

Hi all,
I have a java application consisting of 3 packages & a jar file in the following hierarchy:
-Project
-classes
-src
-package1
-package2
-package3
-file.jar
The main class exists in package2 and uses classes within file.jar
I want the steps to compile and execute the project using command prompt in windows such that the generated classes will be saved in the classes directory
Can anyone help?
Thanx in advance

Hey,
If your source(*.java) files are in src folder and ur currnet directory is project
and you want all your class files to be classes folder then you can try this :
c:\project>javac -cp src\file.jar -d classes\ src\*.javaAssuming that your file.jar file is in src folder.
The above command will set the classpath to src\file.jar (-cp src\file.jar)
-d classes\ - will generate all your class files with package hierarchy if any into classes directory.
src\*.java - specifies the files to be compiled.
Hope this helps.

How can I boot to command prompt in w2003K

I have to access regedit to change the registry before my machine will boot.
Cannot log in to windows at all.
Thanks in advance for the help.

Surely you didn't edit the one and only copy. This one might help.
http://support.microsoft.com/kb/223188
If you ever backed up the reg you could restore the system hive from
%windir%\repair\regback\
Failing that you could use the as-installed system hive from
%windir%\repair\
The system hive contains the driver registrations and the system services configurations. Most likely is at least reinstalling the hardware and applications.

F8 Command Prompt not working

Hi,
We're running SCCM 2012 R2 CU2. Our boot images have Enable command support enabled. I am able to use F8 to get a command window at the Welcome to the Task Sequence Wizard. After the first restart, F8 and Shift-F10 have no effect.
I have a computer that keeps getting hung somewhere in the task sequence but I have no way to get to the logs. If I force power off and power on again, the computer is stuck in the same place again with no command window support. I tried booting to WinPE
and use CMTrace but it cannot access the OS drive from the "in-progress" deployment which I believe could be due to drive encryption.
How do I get the command prompt (F8) to work? I have done some searching and haven't found a solid answer yet.
Thanks,
Rob

You've confirmed that F8 works to open a command prompt in the initial WinPE, but not after the next part, which is an indication that the task sequence switches to using a boot image that doesn't have command prompt enabled. Although you may have already
done this, confirm that the boot image used by the task sequence does indeed have command prompt support enabled.
If all of your boot images do have command prompt support enabled (which, you should be using only one if at all possible), try disabling and re-enabling the support, and confirm that the process finishes correctly.
F8 will work throughout the entire task sequence, if enabled properly.

How do i get a output in CSV of a SQL query executed via SQL Command prompt

Hi All,
I have a question with reference to SQL command prompt. I have a sql query which runs properly and gives proper execution in SQL Management console in GUI.
This report is used to pull the free disk space report of our servers
As i want to schedule it as a report so i want to script it to run via SQL command prompt. I made the script and it works fine if i enter it in SQL command prompt. When i try to extract the output to a CSV File it fails. Below is the details of the command
i am using to query to pull the data. Can anyone help me in getting the output of this query in SQL command prompt.
sqlcmd -W -s , -S Servers FQDN
use operationsmanager
Go
Query:"select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < '20' and CounterName='% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled" -s "," -o "C:\DataSqlCmd.csv"
Go
When i enter the command without the quotes when the query is starting and ending and also without the output command (-s "," -o "C:\DataSqlCmd.csv") it is working and shows the output in the command prompt. Below is the screen shot for
your reference.
Due to security reasons i have to erase the server names:
But when i add the line to extract the output ( -s "," -o "C:\DataSqlCmd.csv") It gives me this error:
The exact command would be:
sqlcmd -W -s , -S CINMLVSCOM01.e2klab.ge.com
use operationsmanager
Go
"select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < '20' and CounterName='% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled" -s "," -o "C:\DataSqlCmd.csv" -h-1
Go
saying the syntax is not correct or some thing as per the below screenshot.
Can any one please help. Below is just the query whi i use to get the output in SQL management studio.
Can any one make a command for the below quer so i can directly execute and test for getting the output.
select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < '20' and CounterName='% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled
Gautam.75801

Can you try the below query?
select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < 20 and CounterName like '% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled
-- replace the below query part in the below SQLCMD C:\>SQLCMD -S SERVERNAME -E -d operationsmanager -Q "select * from sys.databases ds with (nolock) where name='master'" -s "," -o "F:\PowerSQL\MyData.csv" -h -1
SQLCMD -S SERVERNAME -E -d OperationsManager -Q "select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId

How to display Runtime.exec() command line output via swing

Hi all, I'm new to java but have a pretty good understanding of it. I'm just not familiar with all the different classes. I'm having trouble capturing the output from a command I'm running from my program. I'm using Runtime.exec(cmdarray) and I'm trying to display the output/results to a JFrame. Once I get the output to display in a JFrame, I'd like it to be almost like a java command prompt where I can type into it incase the command requires user interaction.
The command executes fine, but I just don't know how to get the results of the command when executed. The command is executed when I click a JButton, which I'd like to then open a JFrame, Popup window or something to display the command results while allowing user interaction.
Any examples would be appreciated.
Thank you for your help in advance and I apologize if I'm not clear.

You can get the standard output of the program with Process.getInputStream. (It's output from the process, but input to your program.)
This assumes of course that the program you're running is a console program that reads/writes to standard input/output.
In fact, you really should read from standard output and standard error from the process you start, even if you're not planning to use them. Read this:

How can I pass a value to the command prompt?

I was wondering how can I pass a value to the command prompt with Windows and Linux? I'm more interested in Linux's system than Windows though. Is there a way to return info from the command prompt?

Here is a snippet from http://mindprod.com/jglossexec.html that explains how in detail.
Runtime.getRuntime().exec("myprog.exe") will spawn an external process that runs in parallel with the Java execution. In Windows 95/98/ME/NT/2000/XP, you must use an explicit *.exe or *.com extension on the parameter. It is also best to fully qualify those names so that the system executable search path is irrelevant, and so you don't pick up some stray program off the path with the same name.
To run a *.BAT, *.CMD, *.html *.BTM or URL you must invoke the command processor with these as a parameter. These extensions are not first class executables in Windows. They are input data for the command processor. You must also invoke the command processor when you want to use the < > | piping options, Here's how, presuming you are not interested in looking at the output:
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat" );
Runtime.getRuntime( ).exec ("cmd.exe /E:1900 /C MyCmd.cmd" );
Runtime.getRuntime( ).exec ("C:\\4DOS601\\4DOS.COM /E:1900 /C MyBtm.btm" );
Runtime.getRuntime( ).exec ("D:\\4NT301\\4NT.EXE /E:1900 /C MyBtm.btm" );
There are also overloaded forms of exec(),
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null);
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null, "C:\\SomeDirectory");
The second argument can be a String [], and can be used to set environment variables. In the second case, "C:\\SomeDirectory" specifies a directory for the process to start in. If, for instance, your process saves files to disk, then this form allows you to specify which directory they will be saved in.
Windows and NT will let you feed a URL string to the command processor and it will find a browser, launch the browser, and render the page, e.g.
Runtime.getRuntime( ).exec ("command.com http://mindprod.com/projects.html" );
Another lower level approach that does not require extension associations to be quite as well set up is:
Runtime.getRuntime( ).exec ("rundll32 url.dll,FileProtocolHandler http://mindprod.com/projects.html" );
Note that a URL is not the same thing as a file name. You can point your browser at a local file with something like this: file://localhost/E:/mindprod/jgloss.html or file:///E|/mindprod/jgloss.html.
Composing just the right platform-specific command to launch browser and feed it a URL to display can be frustrating. You can use the BrowserLauncher package to do that for you.
Note that
rundll32.exe url.dll,FileProtocolHandler file:///E|/mindprod/jgloss.html
won't work on the command line because | is reserved as the piping operator, though it will work as an exec parameter passed directly to the rundll32.exe executable.
With explicit extensions and appropriately set up associations in Windows 95/98/ME/NT/2000/XP you can often bypass the command processor and invoke the file directly, even *.bat.
Similarly, for Unix/Linux you must spawn the program that can process the script, e.g. bash. However, you can run scripts directly with exec if you do two things:
Start the script with #!bash or whatever the interpreter's name is.
Mark the script file itself with the executable attribute.
Alternatively start the script interpreter, e.g.
Runtime.getRuntime( ).exec (new String[]{"/bin/sh", "-c", "echo $SHELL"}";

Reading newly opened command prompt output

I need to use SSH to connect to a server. Rather than downloading a third party SSH API, I would like to use Putty which is already on my computer. The problem is that when using Putty from the command line to connect to a server it opens the connection in a completely different command prompt window instead of the original window. How would I read the output from the new window? I believe this code would have worked if it opened the connection in the same command prompt window...
try{
File test = new File("c:\\program files\\putty");
Runtime rt = Runtime.getRuntime();
Process output = rt.exec("cmd /c putty.exe -ssh username@host", null, test);
BufferedReader br = new BufferedReader (new InputStreamReader(output.getInputStream()));
String line = null;
while((line = br.readLine()) != null )
{ System.out.println(line); } // display process output
int exitVal = output.waitFor(); // get process exit value
System.out.println("Process Exit Value : "+ exitVal);
catch(IOException ioe){
System.err.println(ioe);
catch (Throwable t) {
t.printStackTrace();
}

How to clear the screen in the command prompt?

Hello Everyone,
I was wondering how we can clear the screen in the command prompt in Java. I remember we can do this in C by writing system("cls");
What is the best IDE for writing Java programs. Is the NetBeans IDE good? Thank you very much.

I was wondering how we can clear the screen in the
command prompt in Java. I remember we can do this in
C by writing system("cls");I guess there's no Java way of doing that because it's a function of the shell you're calling. If you try to use Runtime.exec on cls, it starts yet another shell, clears that, and closes it again, so it has no effect on your output.
You could try using the '\b' backspace character, if that helps.
What is the best IDE for writing Java programs. Is
the NetBeans IDE good? Thank you very much.By the way you're asking this question, the answer will be almost certainly "none". If you want to, you can search this board for the few million times this question was asked before, pick all IDEs suggested there and use the one you're most comfortable with.
