问题 When I run the following command (or any command with a pipe | in it) on my machine: dir | findstr "Directory" I get the following message: The filename, directory name, or volume label syntax is incorrect. Running dir command or findstr command by themselves works just fine. The volume label is: vol Volume in drive C is OSDisk Volume Serial Number is 685C-A5B5 The version is: ver Microsoft Windows [Version 6.1.7601] 回答1: As previously mentioned by @dbenham You need to make sure your COMSPEC

问题 I'd like to read/return a single character from a batch script without having to hit the enter key, like getChar() in C/C++. How would I do this? 回答1: Use the CHOICE command Example borrowed from this site @echo off :menu cls echo. echo A - Text for item A echo B - Text for item B echo C - End echo. choice /c:ABC > nul if errorlevel 3 goto end if errorlevel 2 goto B if errorlevel 1 goto A echo Error... choice not installed goto end :A echo Commands for item A pause goto menu :B echo Commands

问题 I was surprised if there is any way to run Java Swing or AWT under a DOS operating system, like freedos. Is there any other way to run a Java GUI under DOS? 回答1: Not exactly DOS, but you can try Charva which is like 'ncurses' for Java ? 回答2: This claims to have some GUI functionality, but very slow! http://sourceforge.net/projects/jaguid/ 回答3: There was a port of Kaffe for DOS, but it could only run headless (without GUI). So I think the answer is no. 回答4: There was a VM for DOS called JavaPC

问题 I'm using Tasm 1.4. I'm trying to change the color of the background and text without clearing the previous text, but it always ends up on clearing the previous text although the colors are changed. For example: mov ah,09h lea dx,text1 int 21h ;displays text1 mov ah,01h int 21h ;I input a character mov ah,06h mov bh,42h mov cx,0000h mov dx,184fh int 10h ;I use this to change the text and background color mov ah,02h mov bh,00h mov dh,0ch mov dl,20h int 10h ;along with this mov ah,09h lea dx

问题 I need to replace some text in a JNLP file using a DOS batch file to tune it for the local machine. The problem is that the search pattern contains an equals sign which is messing up the string replacement in the batch file. I want to replace the line, <j2se version="1.5" initial-heap-size="100M" max-heap-size="100M"/> with specific settings for the initial and max heap sizes. For example at the moment I have, for /f "tokens=* delims=" %%a in (%filePath%agility.jnlp) do ( set str=%%a set str=

问题 In my assembly language class, our first assignment was to write a program to print out a simple dollar-terminated string in DOS. It looked something like this: BITS 32 global _main section .data msg db "Hello, world!", 13, 10, ’$’ section .text _main: mov ah, 9 mov edx, msg int 21h ret As I understand it, the $ sign serves to terminate the sting like null does in C. But what do I do if I want to put a dollar sign in the string (like I want to print out "it costs $30")? This seems like a

问题 Suppose I have a directory A, and subdirectory B. I cd into A and launch lisp. In that lisp process, I would like to launch a Python subprocess where Python sees B as its current working directory. The lisp process needs to have cwd in A, and the python process should have cwd in B. How do I do this in a cross-platform, simple way? I'm looking for a solution that works with CCL and SBCL (probably using 'run-program function), and works for Windows, Linux, and OS X. I looked at the CCL run
