我发现每次使用
将所有文件连接到一个文件中copy *.txt all.txt
，文件末尾有一个Ctrl-Z字符。我不想要这个角色。有没有办法编写批处理脚本来删除此字符或避免这种情况发生？
我想做的是
cat *.txt > all.txt
在linux中。

在CP / M天中，文件大小不是以字节记录，而是以128字节的BLOCKS记录。因此，有必要分配一个END-OF-FILE字节（^ Z = 1AH）来表示部分填充的文本文件块（并且no-EOF意味着“完全填充最后128字节的块”）
该公约受到MSDOS及其衍生产品的尊重 - 这就是COPY CON: filename被^ Z终止的原因。
COPY命令允许对^Z进行不同的解释 - 因此/a和/b模式，如下面的代码所示：
@ECHO OFF
SETLOCAL
:: set COPYCMD=Y to auto-allow overwriting of destination
SET copycmd=Y
:: copy using FRED1.txt (no ^Z-terminal)
>NUL COPY /a fred1.txt freda1.txt
>NUL COPY fred1.txt fred1a.txt /a
>NUL COPY /b fred1.txt fredb1.txt
>NUL COPY fred1.txt fred1b.txt /b
>NUL COPY /a fred1.txt freda1a.txt /a
>NUL COPY /a fred1.txt freda1b.txt /b
>NUL COPY /b fred1.txt fredb1a.txt /a
>NUL COPY /b fred1.txt fredb1b.txt /b
DIR fred*1*|FIND /i "fred"
ECHO.
:: copy using FRED2.txt (has ^Z-terminal) to fred*2*
>NUL COPY /a fred1.txt fred2.txt
>NUL COPY /a fred2.txt freda2.txt
>NUL COPY fred2.txt fred2a.txt /a
>NUL COPY /b fred2.txt fredb2.txt
>NUL COPY fred2.txt fred2b.txt /b
>NUL COPY /a fred2.txt freda2a.txt /a
>NUL COPY /a fred2.txt freda2b.txt /b
>NUL COPY /b fred2.txt fredb2a.txt /a
>NUL COPY /b fred2.txt fredb2b.txt /b
DIR fred*2*|FIND /i "fred"
ECHO.
:: append-copy using FRED1.txt+FRED2.txt to fred*3*
>NUL COPY /a fred1.txt+fred2.txt freda3.txt
>NUL COPY fred1.txt+fred2.txt fred3a.txt /a

>NUL COPY /b fred1.txt+fred2.txt fredb3a.txt /a
>NUL COPY /b fred1.txt+fred2.txt fredb3b.txt /b
DIR fred*3*|FIND /i "fred"

:: append-copy using FRED2.txt+FRED2.txt to fred*4*
>NUL COPY /a fred2.txt+fred2.txt freda4.txt

DIR fred*4*|FIND /i "fred"
ECHO.
GOTO :EOF

请注意juxataposing /a和/b如何产生不同的结果，所有结果都包含^Z - 包含甚至附加。
另请注意，如果源是BINARY文件并且省略COPY开关，则简单/b可能会失败。我从来没有调查过它，但我发现它偶尔会复制.MPG。我怀疑如果^Z在任何字节＆gt; = 80H之前出现在文件中，那么该文件被假定为ASCII并因此在那里毫不客气地终止 - 但正如我所说，我没有调查它。

试试这个：
copy /b *.txt all.txt
如需帮助，请输入help copy。
