===== 文件夹结构 =============================================
D:\test
---A Folder 1
|-----A file 1.txt
|-----A file 2.txt
|-----A file 3.txt
---B Folder 2
|-----B file 1.txt
|-----B file 2.txt
|-----B file 3.txt
|---B Folder 3
|-----B sub file 1.txt
|-----B sub file 2.txt
|-----B sub file 3.txt
@echo off
set work_path=D:\test
D:
cd %work_path%
for /R %%s in (.,*) do (
echo %%s)
pause
结果
D:\test\.
D:\test\A Folder 1\.
D:\test\A Folder 1\A file 1.txt
D:\test\A Folder 1\A file 2.txt
D:\test\A Folder 1\A file 3.txt
D:\test\B Folder 2\.
D:\test\B Folder 2\B file 1.txt
D:\test\B Folder 2\B file 2.txt
D:\test\B Folder 2\B file 3.txt
D:\test\B Folder 2\B Folder 3\.
D:\test\B Folder 2\B Folder 3\B sub file 1.txt
D:\test\B Folder 2\B Folder 3\B sub file 2.txt
D:\test\B Folder 2\B Folder 3\B sub file 3.txt
================================================================
@echo off
set work_path=D:\test
D:
cd %work_path%
for /R %%s in (.) do (
echo %%s
)
pause
结果
D:\test\.
D:\test\A Folder 1\.
D:\test\A Folder 1\A file 1.txt
D:\test\A Folder 1\A file 2.txt
D:\test\A Folder 1\A file 3.txt
D:\test\B Folder 2\.
D:\test\B Folder 2\B file 1.txt
D:\test\B Folder 2\B file 2.txt
D:\test\B Folder 2\B file 3.txt
D:\test\B Folder 2\B Folder 3\.
D:\test\B Folder 2\B Folder 3\B sub file 1.txt
D:\test\B Folder 2\B Folder 3\B sub file 2.txt
D:\test\B Folder 2\B Folder 3\B sub file 3.txt
那么
for /R %%s in (.,*) do (
echo %%s)
和for /R %%s in (.) do (
)
的区别是什么呢？
在有cd %work_path% 的时候，这两个命令执行的结果是一样的，就像我们上面举的例子。但是
for /R %%s in (.,*) do (
echo %%s)
的批处理中没有cd %work_path% ，那么显示的将是这个批处理文件所在文件夹下面的遍历结果。
================================================================
@echo off
for /R "D:\test" %%s in (.) do (
echo %%s
)
pause
结果
D:\test\.
D:\test\A Folder 1\.
D:\test\B Folder 2\.
D:\test\B Folder 2\B Folder 3\.
================================================================
@echo off
for /R "D:\test" %%s in (.,*) do (
echo %%s
)
pause
结果
D:\test\.
D:\test\A Folder 1\.
D:\test\A Folder 1\A file 1.txt
D:\test\A Folder 1\A file 2.txt
D:\test\A Folder 1\A file 3.txt
D:\test\B Folder 2\.
D:\test\B Folder 2\B file 1.txt
D:\test\B Folder 2\B file 2.txt
D:\test\B Folder 2\B file 3.txt
D:\test\B Folder 2\B Folder 3\.
D:\test\B Folder 2\B Folder 3\B sub file 1.txt
D:\test\B Folder 2\B Folder 3\B sub file 2.txt
D:\test\B Folder 2\B Folder 3\B sub file 3.txt
这样的话看出来区别了吧。
再看一个=================================
@echo off
for /R "D:\test" %%s in (*) do (
echo %%s
)
pause
结果
D:\test\A Folder 1\A file 1.txt
D:\test\A Folder 1\A file 2.txt
D:\test\A Folder 1\A file 3.txt
D:\test\B Folder 2\B file 1.txt
D:\test\B Folder 2\B file 2.txt
D:\test\B Folder 2\B file 3.txt
D:\test\B Folder 2\B Folder 3\B sub file 1.txt
D:\test\B Folder 2\B Folder 3\B sub file 2.txt
D:\test\B Folder 2\B Folder 3\B sub file 3.txt
就是只显示了文件
