将文件从父目录复制到许多子目录中的特定文件夹的 DOS 命令

发布于 2024-11-25 06:57:17 字数 533 浏览 2 评论 0原文

我正在尝试自学一些简单的 DOS 命令，并使用相对简单的命令来复制或移动文件，但是这个特定的请求对我来说是一个挑战，并且希望能从这个论坛获得一些专业知识。

C:\Parent\library.eds   (location of my source file)

每当我更新父目录中的library.eds时，我都想将该文件复制到包含名为“LIB”的文件夹的每个子目录中。我已将子目录标准化为以下内容：

C:\Parent\Child1\INPUT
C:\Parent\Child1\OUTPUT
C:\Parent\Child1\LIB      {paste library.eds here}

C:\Parent\Child2\INPUT
C:\Parent\Child2\OUTPUT
C:\Parent\Child2\LIB      {paste library.eds here}

并循环直到所有具有 LIB 目录的子目录都包含更新的文件“library.eds”

谢谢您的帮助！标记

I'm trying to teach myself some simple DOS commands and have used relatively simple commands to copy or move files, however this specific request is presenting a challenge for me and would appreciate some expertise from this forum.

C:\Parent\library.eds   (location of my source file)

Any time I update library.eds in the parent directory, I would like to copy that file into every Child directory that contains a folder named "LIB". I have standardized the Child directories to the following:

C:\Parent\Child1\INPUT
C:\Parent\Child1\OUTPUT
C:\Parent\Child1\LIB      {paste library.eds here}

C:\Parent\Child2\INPUT
C:\Parent\Child2\OUTPUT
C:\Parent\Child2\LIB      {paste library.eds here}

and loop through until all children with LIB directories contain the updated file "library.eds"

Thank you for your help!

下面是一个可以帮助您入门的命令：

FOR /F "delims=" %%D IN ('DIR /b /a:D /s C:\Parent\LIB') DO @ECHO COPY "C:\Parent\library.eds" "%%~D"

一旦您让它按照您想要的方式工作，请删除 @ECHO 部分以实际执行复制：

FOR /F "delims=" %%D IN ('DIR /b /a:D /s C:\Parent\LIB') DO COPY "C:\Parent\library.eds" "%%~D"

这些命令的额外帮助

HELP FOR
HELP DIR

这是如何工作的

FOR /F ... %variable IN ('command') DO otherCommand %variable...

这可以让您执行 < code>command，并循环其输出。每行都将被填充到 %variable 中，并且可以在 otherCommand 中展开任意多次，无论您喜欢在哪里。 %variable在实际使用中只能是单字母名称，例如%V。

"delims="

这使您可以忽略 'command' 输出的任何空格，因此它可以正确处理名称中包含空格的目录。

DIR /b /a:D /s C:\Parent\LIB

这将搜索 C:\Parent 下名为 LIB 的所有文件。由于/s，它将递归地遍历子目录。它只会查找目录（因为 /a:D）。由于 /b，它将以对循环有用的方式输出它们。

%%D instead of %D

这在批处理文件中是必需的。如果您在命令提示符下执行此操作，则可以使用 %P 代替。

Here's a command that can get you started:

FOR /F "delims=" %%D IN ('DIR /b /a:D /s C:\Parent\LIB') DO @ECHO COPY "C:\Parent\library.eds" "%%~D"

Once you get it working the way you want, remove the @ECHO part to actually do the copy:

FOR /F "delims=" %%D IN ('DIR /b /a:D /s C:\Parent\LIB') DO COPY "C:\Parent\library.eds" "%%~D"

Extra help for these commands

HELP FOR
HELP DIR

How this works

FOR /F ... %variable IN ('command') DO otherCommand %variable...

This lets you execute command, and loop over its output. Each line will be stuffed into %variable, and can be expanded out in otherCommand as many times as you like, wherever you like. %variable in actual use can only have a single-letter name, e.g. %V.

"delims="

This lets you ignore any whitespace output by 'command', so it properly handles directories that have spaces in their names.

DIR /b /a:D /s C:\Parent\LIB

This will search for all files under C:\Parent that have the name LIB. It will recursively go through subdirectories because of /s. It will only find directories (because of /a:D). It will output them in a way that is useful for looping, because of /b.
