中国DOS联盟

I have downloaded the pure DOS version of sed from your Google forum and copied it to the C drive. I also modified test1.bat and test2.bat according to your code, but the following error still occurs:

c:\>type a.txt
19

c:\>test1

General error reading drive F
A: Abort, R: Retry, F: Fail? a
c:\>

I don't know what's wrong. Please ask the experts for advice.

Re - test found that when entering sed /? at the command line, the following appears:

General error reading drive F
A: Abort, R: Retry, F: Fail? a

Test environment: DOS 7.1

Oh, you're too... Is the C drive Fat32? Is the C drive in the Path? Is the C drive indeed drive C under DOS? Under DOS, first find sed, or put sed test1 test2 together

They are together, and it's a DOS virtual machine made with Microsoft Virtual PC. The file format is Fat32, and the installed system is DOS 7.1. All the files are in the same directory. test1.bat, test2.bat, sed.exe, and the previously mentioned find.exe, etc., are all together. Thanks!

I'm sorry, they are all placed in the root directory of drive C:, including A.TXT. They were copied from drive E:. The same problem occurs under drive E:.

You need to change your path variable, otherwise there will be endless troubles.
Or try this:

@echo off
call test2.bat 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

:start1
if "%1"=="" goto end
.\sed -n "/%1/p" A.TXT>nul
if not errorlevel 1 if errorlevel 0 goto xxx
shift
goto start1
goto end

:xxx
shift
echo %1>A.TXT

:end

c:\>type a.txt
2

General error reading drive F
A: Abort, R: Retry, F: Fail? f
Load error: no DPMI - Get csdpm*b.zip

When the "General error reading drive F" prompt appears, entering "f" results in "Load error: no DPMI - Get csdpmi*b.zip"

Ask: What is "DPMI"? What does the above mean? How to solve it?

Oh, I also overlooked that DPMI is DOS Protected Mode Interface, which provides protection mode support under DOS
http://www.cn-dos.net/forum/viewthread.php?tid=17093&fpage=1&highlight=DPMI

Tested this one and it's not very stable. Download the one recommended by the webmaster:
http://www.cn-dos.net/forum/viewthread.php?tid=18577&fpage=1

Thanks for the instruction. Run again:

C:\>DPMI.EXE
C:\>TYPE A.TXT
2

C:\>TEST1
C:\>TYPE A.TXT
2

After running DPMI.EXE, there are no errors, but the content in A.TXT is not added and remains the original value. Also, does DPMI need to be run once before each time sed.exe is run?

Thanks!

I also tried, it's still unstable.
You can download the latest version of DPMI here http://japheth.de/Download/HXRT.ZIP
sed.exe can also consider using the latest version. vkill has 3 versions of sed http://www.vkill.net

The expert upstairs, the problem still hasn't been solved! Help me, thank you!

The sed.exe in Http://www.vkill.net was not found

The problem is not solved, and I won't add it! :(:(:(

Asking boss fastslz, is there a way to solve it?

Thank you!

Try using fc

test1.bat
--------------------------------------------------------------------------------------------
@echo off
call test2.bat 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
type A.TXT
--------------------------------------------------------------------------------------------
test2.bat
--------------------------------------------------------------------------------------------
:start1
echo %1 > A2.TXT
fc A.TXT A2.TXT > nul
shift
if "%1"=="" goto end
if errorlevel 1 goto start1

echo %1 > A.TXT

:end
