Question

我正在尝试编写一个批处理文件，该文件将计算当前目录中有多少个文件和多少个目录。

for /r %%i in (dir) do (
    if exist %%i\* (
        set /a directories=directories+1
    ) else (
        set /a files=files+1
    )
)
echo directories
echo files

这是我尝试运行此批处理文件的目录结构：

---directory
   ---file1
---file2

这总是返回“2个文件”和“0个目录”。

Answer 1

for /r将递归搜索目录（默认情况下会搜索当前目录） - *将返回目录树中的所有文件，.将返回树中的所有目录

@echo off

set files=
set directories=

for /r %%a in (*) do set /a files+=1
for /r %%b in (.) do set /a directories+=1

echo files:     %files%
echo directories:   %directories%

查看for命令帮助页面 -

h:\>for /?

FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]

    Walks the directory tree rooted at [drive:]path, executing the FOR
    statement in each directory of the tree.  If no directory
    specification is specified after /R then the current directory is
    assumed.  If set is just a single period (.) character then it
    will just enumerate the directory tree.

Answer 2

试试这个：

@echo off
set total=0
set dir=0
set files=0
for /f %a in ('dir /b') do (set /a total+=1)
for /f %a in ('dir /b /a:d') do (set /a dir+=1)
set /a files=%total%-%dir%

Echo There are %dir% direcotries and %files% files in the current directory alone

这也不会计入子目录，您可以使用for /r和for /r /d。

希望这有帮助，莫娜。
