command

问题 I have the batch file which has the command to call second.bat file. It will produce single line of output when it called. I want to store that line into variable. CALL second.bat I have tried using the following lines of commands but no use FOR /F "tokens=* USEBACKQ" %%F IN ('COMMAND') do SET result=%%F FOR /F "tokens=1 delims= " %%A IN ('COMMAND') DO SET NumDocs=%%A I don't know what to replace with COMMAND 回答1: As the help will tell you, COMMAND should be the command you want to run and

问题 I am making a batch file that needs to copy another batch file into the Start Menu Start Up folder (the one used when a program launches on login/start up) . Since the path uses the user's computer name eg. C:\Documents and Settings\User Name I need the batch file to get the user's correct name instead of the "User Name" or * (wildcard). Wildcards doesn't work as the batch file comes up with " the filename directory name or volume label syntax is incorrect ". I hope this is clear enough. 回答1:

问题 EDIT: The code now works! Here's how I did it: package me.nrubin29.jterminal; import javax.swing.*; import javax.swing.filechooser.FileSystemView; import javax.swing.text.SimpleAttributeSet; import javax.swing.text.StyleConstants; import java.awt.*; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import java.io.*; import java.util.ArrayList; public class JTerminal extends JFrame { private JTextPane area = new JTextPane(); private JTextField input = new JTextField("Input");

问题 I am absolutely brand new to any kind of development but need a batch job to copy a file from one folder to another. The problem is that the source folder is dynamically named. The folder name will contain the current date and a suffix number (eg. "TestRun_20141106_13") - so I will never be able to determine the 'latest' version of the folder before running the batch / copy job. Can anyone help please? I know this will be easy for someone but as I said, I am a complete noob!! Thanks in

问题 I wish to capture tcpdump traffic on two different ports simultaneouly . I tried this .. $ tcpdump port 21 ; tcpdump port 22 Althoug it worked but problem is first it will wait for traffic on port 21 and when interrupted then it will wait for port 22. Also another problem is it will not capture the traffic on port 22 untill traffic on port 21 will be captured. I want an order free solution means in whatever order packet arrives if they are for port 21 or 22 they should be captured . Please

问题 I know there are many threads about this, but none of them worked for me. Here is what I am trying to do: Javac and run a file from my java code. It works for Windows but I would like to make it also work on UNIX. Here the code: if(os.equals("win")){ //For Windows try { Runtime.getRuntime().exec( "cmd /c start cmd.exe /K " + "\"cd " + path + "&& " + "javac " + name + ".java && " + "echo ^>^>" + name + ".java " + "outputs: &&" + "echo. &&" + "java " + name + " && " + "echo. &&" + "pause && " +

问题 OK, I tend to avoid using commands because they always manage to confuse the hell out of me, but I'm on a new project and am trying to architect it correctly with no code behind on my view. Basically All I am trying to do right now is wire up a button that fires a command that does some things on my view model, and somehow something so simple is still giving me trouble. I think I'm close but can't quite get there. Here is what I have right now. <Window.Resources> <RoutedUICommand x:Key=

问题 I have a static class which contains a RoutedUICommand that I would like to use in binding. public static class CommandLibrary { public static ProjectViewModel Project { get; set; } public static RoutedUICommand AddPage { get; private set; } static CommandLibrary() { AddPage = new RoutedUICommand("AddPage", "AddPage", typeof(CommandLibrary)); } public static void AddPage_Executed(object sender, ExecutedRoutedEventArgs args) { Project.AddPage(); } public static void AddPage_CanExecute(object
