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

问题描述

我想将所有文件(包括它们的绝对路径)的列表放入一个变量中，用空格分隔.我的 Google-fu 在这方面似乎很弱，因为我一直遇到问题.

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.

我有一个存储在 %baseDir% 中的基本目录，我想解析它的文件(不递归或包含子目录).就像我提到的，这需要进入一个列表.我想我可以使用一个不错的小快捷方式，但是 for 循环和连接也可以做到这一点.

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.

理想情况下，我会有这样的东西:

Ideally, I'd have something like this:

echo fileList

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

推荐答案

很简单:

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

事实上，您也可以在 set 命令的帮助中找到这个非常示例，可通过 help set 访问，并附有解释为什么天真的方法不会工作.

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.

要使用不同的文件集(而不是所有)，您可以轻松更改通配符:

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
