Question

How do I capture text from debug.exe in a command window?

Asked by: jc37

I am using debug.exe for assembly language, and the screen buffer resets to 25 lines when I run debug.exe in a command window. I am therefore unable to view lines that run off the window.

Running

C:\>debug >c:\capture.txt

almost works, as all input and output is sent to the capture.txt file, but not displayed in the command window.

Does anyone know how I can see and capture at the same time?

*Copy and paste, 25 lines at a time, is extremely time consuming.

What happens if you right-click on the title bar of the window?  Do you get an Edit option?  If so try Select All then Copy.

Sure:

C:\>debug >c:\capture.txt 
Type c:\capture.txt

Or I guess that would be:

C:\>debug >c:\capture.txt 
C:\>Type c:\capture.txt

Output to a file works perfectly. The problem is the output only goes to a file, and not to the screen.

For example, by typing the following into cmd.exe

C:\>debug >c:\capture.txt
R
Q

capture.txt contains the following:

-R
AX=0000  BX=0000  CX=0000  DX=0000  SP=FFEE  BP=0000  SI=0000  DI=0000  
DS=0B0B  ES=0B0B  SS=0B0B  CS=0B0B  IP=0100   NV UP EI PL NZ NA PO NC
0B0B:0100 7518          JNZ      011A                              
-Q

This is exactly correct.
What I am trying to accomplish is to see the output in capture.txt in cmd.exe also.

I think I need a program that reads the command window buffer  and writes it to a file.

This batch command:

Type c:\capture.txt

will read the file (c:\capture.txt) and output it to the screen.  It should do just what you're asking

 

by: oBdAPosted on 2009-09-20 at 14:46:45ID: 25379120

Pipe the debug output through tee.exe:
debug | tee "capture.txt"
GNU utilities for Win32
http://unxutils.sourceforge.net/

 

by: jc37Posted on 2009-09-20 at 14:56:53ID: 25379175

The batch command Type is a nice suggestion.

Partial solution: If I have 2 command windows open at the same time, one for debug, another for issuing Type after each debug command.

The problem is I can't see what I am typing into debug.

 

by: jc37Posted on 2009-09-20 at 15:17:35ID: 31631181

I knew about tee, but I never knew about tee.exe!

Thank you so much. I am going to pass this info off to all my friends in my Microprocessor Design class.
