批处理文件 - 文件写入变量列表 [英] Batch file - Write list of files to variable

问题描述

我想获得的所有文件（包括绝对路径）到一个变量，用空格分隔的列表。我的谷歌福似乎是弱在这方面，因为我一直运行到的问题。

我保存在％BASEDIR％基本目录，并想解析它的文件（不递归或包括子目录）。就像我提到的，这需要去到一个列表。我想像有一个可爱的小捷径，我可以使用，但一个for循环和串联会做的伎俩也。

在理想情况下，我想有这样的事情：

 回声的fileListC：\\ file1.c中C：\\ file2.c中C：\\ file3.c中
 

解决方案

pretty简单：

  SETLOCAL enabledelayedexpansion ENABLEEXTENSIONS
集列表=
在%% X（％BASEDIR％\\ *）做设置LIST =！LIST！ ％％X
集LIST =％LIST：〜1％
 

事实上，你会发现这个非常例子也帮助了设置命令，获取通过帮助制定 ，配有一个解释，为什么幼稚的做法是行不通的。

要使用一组不同的文件（而不是所有的），你可以很容易地改变通配符：

  %%用于中的x（％BASEDIR％\\ *。c）段设置LIST =！LIST！ ％％X
 

I'd like to get a list of all files (including their absolute path) into a variable, separated by spaces. My Google-fu seems to be weak in this regard, because I keep running into issues.

I have a base directory stored in %baseDir%, and would like to parse it for files (not recursing or including sub-directories). Like I mentioned, this needs to go into a list. I'd imagine there's a nice little shortcut I could use, but a for loop and concatenation would do the trick as well.

Ideally, I'd have something like this:

echo fileList

C:\file1.c C:\file2.c C:\file3.c

解决方案

Pretty simple:

setlocal enabledelayedexpansion enableextensions
set LIST=
for %%x in (%baseDir%\*) do set LIST=!LIST! %%x
set LIST=%LIST:~1%

In fact, you find this very example also in the help for the set command, accessible via help set, complete with an explanation why the naïve approach won't work.

To use a different set of files (rather than all), you can easily change the wildcard:

for %%x in (%baseDir%\*.c) do set LIST=!LIST! %%x
