Command Line Output Parsing

I am writing a program that runs a load utility via a
class that returns the load utilities output via a
string. There is a certain part of this output which
i need to determine if the program has successfully
completed. I am looking for suggestions on how to
accomplish this. Below is an example of the commands
output.
Rows Read : 30000
Rows Rejected : 0
Rows Loaded : 30000
Rows Committed: 30000What constitutes a successful run?
Might want to take a look at the String.startsWith() and String.indexOf() methods:

Capturing command line output to a file possible?

Hi, i am in need of capturing the command line output to a txt file and need some suggestions on how to do it.
I have two classes, class A is the one with all the methods and outputs text to the command line (using System.out.print). class B is the one that calls the methods and needs to record the command line output to a file.
Now the problem i face is not all the output is going to be written to a file and not all the output is going to be displayed on the command line. eg. class B will have a way to select the output mode which is either both to a file and command line or just to a file and display nothing on the command line.
Is what i am asking even possible? Any suggestions would be great!

Here is a class I found on the forum that does basically what you need. Just change the code that is updating a Document to write to a file:
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;
public class ConsoleOutputStream extends OutputStream
     private Document document = null;
     private ByteArrayOutputStream outputStream = new ByteArrayOutputStream(256);
     private PrintStream ps = null;
     public ConsoleOutputStream(Document document, PrintStream ps)
          this.document = document;
          this.ps = ps;
     public void write(int b)
          outputStream.write (b);
     public void flush() throws IOException
          super.flush();
          try
               if (document != null)
                    document.insertString (document.getLength (),
                         new String (outputStream.toByteArray ()), null);
               if (ps != null)
                    ps.write (outputStream.toByteArray ());
               outputStream.reset ();
          catch(Exception e) {}
     public static void main(String[] args)
          JTextArea textArea = new JTextArea();

               new ConsoleOutputStream (textArea.getDocument (), System.out), true));

               new ConsoleOutputStream (textArea.getDocument (), null), true));

Parsing java command line output to a gui

Dear All,
I am trying to implement a search engine for a project, i have a java file called Searcher.java, which searches for a particular text or sentence and gives the output based on the number of hits on a particular document, the document with the max hits is displayed first and so on,all the documents are are stored in a text file, I am trying to create a GUI for this file, the gui would consist of a text box,submit button,a list and a text area , when a user enters the text to search all the entries are displayed in the list box and upon clicking the individual item in the list the description should open up in the text area.
The problem i am encountering is that i am not able to parse the output of the searcher.java file onto the GUI, i have no clue as to how to implement it , i would really appreciate it if anyone could help me out.
the code for Searcher.java is as follows
import java.util.*;
public class Searcher {
/** Specify the work directory !! */
private static final String rootDir = "C:/HR/GUIAssign/";//on PC
// private static final String rootDir = "/research/gm/Java/IR/"; // on Unix
private static final String stopWordFile = "iStopWords.txt";
private static final String docCollFile = "iDocColl.txt";
private static final String invertedIndexFile = "ioInvertedIndex.txt";
private StopWordSet stopWords = new StopWordSet(rootDir + stopWordFile);
private Stemmer stemmer = new Stemmer();
private TextTokenizer tok;
private TextParser parser;
private InvertedIndex inv;
/** Creates a new instance of Searcher */
public Searcher(TextTokenizer tok, TextParser parser) {
this.tok = tok;
this.parser = parser;
ReaderWriter rw = new TextFileReaderWriter(rootDir);
inv = rw.readInvertedIndex(invertedIndexFile);
List search(String query) {
System.out.println("\nSearching for <" + query + ">.");
List hits = new ArrayList();
int nbOfDocs = parser.getNbOfReadDocs();
System.out.println("\nSearching for <" + query + "> among " + nbOfDocs +
" documents.\n");
double scores[] = new double[nbOfDocs]; // initial values 0.0
String term;
tok.setText(query);
while(tok.hasMore()) {
System.out.println("\nNext term: ");
term = tok.nextToken();
System.out.println(term);
if(stopWords.contains(term))
continue; // this terms can be ignored
term = stemmer.stem(term); // apply the stemmer to get the root
System.out.println("\n\nInfo on the term \"" + term + "\":");
IndexTerm indexTerm = inv.getIndexTerm(term);
if(indexTerm == null)
System.out.print("Not in the vocabulary.");
else {
System.out.print("It appears " + indexTerm.getTermFreq() + " times, in "
+ indexTerm.getDocFreq() + " documents:\t");
Iterator itr = indexTerm.getIterator();
while(itr.hasNext()) {
DocFreq docFreq = (DocFreq) itr.next();
scores[docFreq.getDocId()] += docFreq.getFreq() /* / indexTerm.getDocFreq() */ ;
// create hits from documents that have non-zero scores
for(int i = 0; i < nbOfDocs; i++)
if(scores[i] > 0.0)
hits.add(new Hit(i, scores));
// sort them in descending order of scores
Collections.sort(hits, new Hit.CompareByScore());
return hits;
* @param args the command line arguments
public static void main(String[] args) {
TextTokenizer tok = TextTokenizer.getTokenizer("alpha");
TextParser parser = new DummyParser(rootDir, tok);
Searcher searcher = new Searcher(tok, parser);
List hits = searcher.search("trade and board coffee, stock x is common");
Iterator it = hits.iterator();
while(it.hasNext()) {
Hit hit = (Hit) it.next();
int index = hit.getDocIndex();
Doc doc = parser.getDoc(index);
System.out.println("\n\nDoc " + index + " has a score of: " +
hit.getScore() + "\n*** " + doc.getTitle() + " ***\n" +
doc.getText());
this code runs perfectly and gives the output on the command line
the code for the GUI is as follows

I'm not positive I understand your problem... but let me recap what I think it is, then provide a solution:
Your searched program can be run from the command line, and prints out (using system.out) the data you want. But NOW you want to create a GUI class, that intercepts that output, and displays it on the screen, and you can't because its going to the output stream and you're GUI isn't able to get it.
If this is the case, what you can do is add two constructors to your Searcher class:
public Searcher()
this(System.out);
public Searcher(OutputStream out)
this.out = out;
The idea being, that if you don't specify an output stream, the output goes to the console like normal. But if you do specify an output stream, the data gets fed back to you. So then in your GUI, you can do some binding of PipedInputStream and PipedOutputStream so when the Searcher class prints out, it comes right through the pipe into your GUI where you are waiting to read it.
If this wasn't your problem, sorry :(

Mashed/compressed command line output

This is rather hard to describe, but after installing Arch on a new machine not long ago, I noticed that in the output of certain programs, some characters were partially or entirely hidden behind others. That is, it appears that certain letters are mostly missing, but little bits of them are still visible behind characters that come later on in the output. If I select the output with my mouse, and copy and paste somewhere else, the entire output is there...it's just not all visible on the command line. Though, as I select with my mouse, the specific text my mouse is over becomes visible and other, adjacent characters are hidden. So far I've seen this running yaourt, as well as in vim (which is really a pain). I use Konsole.
Here's a screenshot, showing the output of `yaourt -Ss digikam`:
Notice how various text fields seem to run into each other, and the end of each field gets clipped. As I said, I see the same behavior within vim, so it's not limited to the output of any particular program. Any ideas what's causing this? Is it a Konsole thing, or could it be related to X somehow, or maybe something else I haven't thought of?

Getting command line output dynamically

I am executing one command line argument through WPF application but not getting any output of command line execution. But if I will execute same command through command line manually then getting out put. I am using synchronous operation and below code.
System.Diagnostics.ProcessStartInfo procStartInfo =
new System.Diagnostics.ProcessStartInfo("cmd", "/C " + commandlinearg);
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = true;
procStartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
procStartInfo.WorkingDirectory = strToolsPath;
procStartInfo.RedirectStandardOutput = true;
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
result = proc.StandardOutput.ReadToEnd();
proc.Close();

Hi Magnus, I am using synchronous operation like below
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
result = proc.StandardOutput.ReadToEnd();
proc.WaitForExit();
if output is very huge then in that case is it required to collect in a huge buffer or below code can collect the out put
result = proc.StandardOutput.ReadToEnd();
because I am using also WaitForExit but still I am not getting out put whereas using same code i am getting output for some commands(which gives less output).

Command Line Output Directory

I am trying to generate my help files through the commanline utitlity via a bat file.
Here is my bat file...
rem Generates the System output files
:START
"c:\Program Files\Adobe\Adobe RoboHelp 8\RoboHTML\RHCL.exe" "c:\Projects\myProj\1.0.0\Development\HelpFiles\MyHelp.xpj" -o
"c:\userName\Desktop\RoboHelpOutput" -g "c:\userName\Desktop\RoboHelpOutput\log.txt"
:END
When I run this, it successfully generates the output files, but it does not generate it in the "c:\userName\Desktop\RoboHelpOutput" directory. Instead, it uses the directory I pointed it at when I generate the output through the RoboHelp UI. I need to figure out why this is ignoring the -o Destination tag in order to be able to work locally and have the help files generated with our automated builds.
Please Help!!!!
Thanks in advance!

Hi - we are having the same issue. Regardless of what we specify as the output folder, the help file always generates the output on the drive we previously specified in the SSL file.
SSL:
<element name="DestinationProjectName" value="X:\doc_4x\html\apps\output\pr\flexi\fpr32.chm" />
We tried to eleminate the X: to see where the file will generate to. This is the path that showed up on the first wizard screen when I went to generate in RH a few minutes later:
X:\doc_4x\html\apps\projects\pr\doc_4x\html\apps\projects\pr\doc_4x\html\apps\output\pr\fl exi\fpr32.chm
Any help in resolving our command line build issue is greatly appreciated!

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:

Display command line output

In my program LabVIEW calls an executable using a batch file and this executable returns a string. Is there a way for LabVIEW to be able to view this output string?

hi
I do not know how your batch files run, but you should get it run properly (with "wait until completion = False) before setting it to TRUE.
If your batch files do not even run correctly (with "wait until completion = False), it will hangs when your run the system exec.vi (with "wait until completion = TRUE).
Hope this is not too confusing....

Class to parse command line arguments.

Hi,
Is there a Class to parse the Command line arguments of a program?
Perhaps something like Getopt in perl.
Thanks,
Anupam.

I'm not sure if this is what you're asking, but it does it for you already. The args[] array in the main method holds the command line arguments parsed with space delimiters. So if on the command line you put:
java MyClass these are arguments
The args array would contain:
args[0] = "these"
args[1] = "are"
args[2] = "arguments"

Is your problem solved yet? If not take a look at this page http://www.labnol.org/software/tutorials/copy-dos-command-line-output-clipboard-clip-exe/2506/

Command line style regular expression string parser

Hi people,
I am currently working on a program where I need to parse a file (or any input stream) line by line. I then need to parse every line for arguments. Each line is formatted similar to how arguments are passed to the command line. The regular expression needs to split every line by any encountered whitespace, but needs to be able to retain any whitespace within double quotes (i.e. "some spaced text here"). Arguments can be numbers, booleans and (quoted) strings. Quoted strings must also be able to have escaped quotes in it (as below). The quotes for the quoted string (the outer ones, obviously not the escaped ones) do not necessarily have to be retained.
An example input line:
arg1 arg2 "arg 3" "arg 4" 987 arg6 "arg \"arg \"arg 7"
Desired example output:
arg1
arg2
arg 3
arg 4
987
arg6
arg "arg "arg 7
After the input line has been split up the program will handle any parsing (i.e. numbers, booleans, etc.). The program currently uses a simple for loop to iterate over all characters in the line and splits it up appropriately by checking every character. However, if this can be done automatically by using a regular expression passed to String.split() (or with some use of the regex package), it would remove quite a bit of redunant code and make the program that much more maintainable.
I do not have much experience with regular expressions since I have never really had the need to use them, but if they can work in this case it would be great.
Thanks in advance for any help.

Almost any parsing problem can be solved if you throw a big enough and ugly enough regex at it, or so I'm told.
I think what you are doing is also amenable to java.io.StreamTokenizer:
import java.io.*;
import static java.io.StreamTokenizer.*;
public class StreamTokenizerExample {
    public static void main(String[] args) throws IOException {
        StringReader input = new StringReader("arg1 arg2 \"arg 3\" \"arg 4\" 987 arg6 \"arg \\\"arg\\\" arg 7\"\nnextline");
        StreamTokenizer in = new StreamTokenizer(input);
        in.eolIsSignificant(true);
        for(int ttype; (ttype = in.nextToken()) != TT_EOF; ) {
            switch (ttype) {
                case TT_WORD:
                    System.out.println("String[" + in.sval + "]");
                    break;
                case TT_NUMBER:
                    System.out.println("number[" + in.nval + "]");
                    break;
                case TT_EOL:
                    System.out.println("[EOL]");
                    break;
                case '"':
                    System.out.println("quoted[" + in.sval + "]");
                    break;
                default:
                    System.out.println("unexpected " + ttype);
{code}

Parsing in Weblogic/jsp doesn't work; application-mode (command-line) works

Hello-
Parsing my XML file in Weblogic/jsp doesn't work, whereas it works
in application-mode... (albeit on two different machines)
Here are the parameters:
server1:
weblogic 6.0
win2k server
jre1.3
my personal machine:
***no weblogic***
win2k server
jre1.3
When I run my code as an application (command-line style) on my machine,
parsing in my xml file works fine, and I can do a root.toString() and it
dumps out the entire xml file, as desired.
However, running my code inside weblogic (on server1) in JSP, parsing in
my file and doing a root.toString() results in the following: [dmui: null]
(where dmui is my root)
(even though i'm running it on two different machines, i'm positive its the
same code (the servers share a mapped drive)...
So, I think its probably because I'm using a different parser, as
specified by weblogic? There are no exceptions being thrown. Here's my
(abbreviated) code, which is called either command line style or in a JSP:
// Imports
import org.w3c.dom.*;
import org.w3c.dom.Document;
import javax.xml.parsers.*;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
DocumentBuilderFactory docBuilderFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
mDocument = docBuilder.parse (inFile);
myRoot.toString()
-END
Doing a System.getProperty("javax.xml.parsers.DocumentBuilderFactory")
results in:
server1 (weblogic/jsp):
"weblogic.apache.xerces.jaxp.DocumentBuilderFactoryImpl"
my machine (application-mode):
null
Does anyone have any ideas about how to get this work? Do I try to set it
up so that they both use the same parser? Do I change the Weblogic parser?
If so, to what? And how?
Am I even close?
Any help would be appreciated..
Thanks, Clint

Hi, Rob
Does it work in WL9.2?
It seems I do it exactly as the explained at http://edocs.bea.com/wls/docs81/programming/classloading.html - and it fails :o(.
I try to run my app.ear with WL9.2 There are 2 components in it: webapp and mdb. The webapp/WEB-INF contains weblogic.xml:
<weblogic-web-app>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>
Mdb is expected to run in the same mode, i.e. to prefer the webapp/WEB-INF/*.jar over the parent Weblogic classloader. To do so I add the weblogic-application.xml to the app.ear!/META-INF:
<weblogic-application>
<classloader-structure>
<module-ref>

<module-uri>webapp</module-uri>
</module-ref>
<classloader-structure>
<module-ref>
<module-uri>mdb.jar</module-uri>
</module-ref>
</classloader-structure>
</classloader-structure>
</weblogic-application>
Now, when classloader-structure specified, both webabb and mdb prefer the weblogic root loader as if prefer-web-inf-classes not defined at all.

Capturing the output of a os command line

I need to capture the output of a os command line executed from one java program and I don't know how can do it.
For example:
Runtime.getRuntime().exec("hostid");

Your suggestion worked very well, just in case that this could interest somebody, this is the complete solution
Thanks for your help
import java.io.*;
public class HostID
public static void main(String args[]){
try{
InputStream in = (Runtime.getRuntime().exec("hostid")).getInputStream();
byte[] arreglo= new byte[200];
int cantidad = in.read(arreglo);
System.out.println(new String(arreglo,0,cantidad));
} catch (IOException ioe){System.out.println(ioe.getMessage());}
}

Unix command Line input and output

Has anybody used Forte for now window application. Passing values through
command line and get put as a return value. I am able to call Forte and
pass input values but I do not know who to get the return value. Here is
the shell script that I am running:
#!/bin/csh
# Ensure that the correct number of parameters were supplied #
if (${#argv} < 2) then
then
echo "USAGE: ecapp Method Number Parm1 Parm2"
exit 1
endif
ftexec -fi bt:$FORTE_ROOT/userapp/mwapp/cl0/mwapp_0 -fnw -fterm $1 $2
The start class will return a string value after processing the request. I
can use task.lgr.putline to output to the screen but that is not what I
would like to do. I want to get the return value assigned to a variable in
the shell script. One thing I do not know is that if Forte return a string
that the script can use. Any help would be appreciated.
thanks in advance

Hi,
Did you try to set Task.Part.OperatingSystem.ExitStatus ? But, the ExitStatus is an integer.
If you really need a string, I would use ExitStatus to know how it finished and an environment variable (Task.Part.OperatingSystem.SetEnv() to position it in your Tool code) to read the string back in the script.
Hope this helps,

Problem Using Sax parser with Eclipse 3.0 and command line

Hi,
I am parsing a xml file with sax. When I am running my programm in the command line everthing is ok and I get the right results from parsing.
But if I am running the programm in Eclipse 3.0 (the same java code) I get an other result (the wrong results).
Does anybody know what this can be the reason for. Is Eclipse using an other xml parser and if where I can change the parser?
It would be very kind if somebody can give me a reason for this strange behaviour.
Thanks in advance

I have solved my problem.
In the command line I used jre 1.4 and in Eclipse I used jre 1.5.
I think jre 1.5 uses an other xml parser so I got an other result.
If i use in Eclipse jre1.4 I get the same result as in the command line.
