計算某個目錄內的文件和文件夾

Question

我試圖編寫一個批處理文件來計算當前目錄中有多少個文件和多少個目錄。

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

這是一個目錄的，我嘗試運行這個批處理文件結構：

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

而且這始終返回「2個文件」和「0目錄」。

Answer 1

試試這個：

@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 

這將不計算子目錄，以及，你會用for /r和for /r /d。

希望這對蒙娜有所幫助。

Answer 2

for /r將遞歸搜索目錄（默認情況下它將搜索當前目錄） - *將返回目錄樹中的所有文件，.將返回樹中的所有目錄。

@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% 

看看for命令幫助頁面 -

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.
