使用Batch到csv输出文件夹名称和文件夹中特定格式的文件[关闭]

Question

我有几个文件夹，它们包含扩展名为 .mdb 和 .mpg（以及更多）的文件。我需要一个输出文件夹名称（第 1 列）、.mdb 文件名（第 2 列）和 .mpg 文件名（第 3 列）的 csv 文件。 .mpg 是多个数

所以输出会是这样的：

输出.csv

    A        B       C
    folder1 abc     xyz
                    hgf
                    pqr

    folder2 lala    didi
                    loc

A、B 和 C 是列。此外，如果可能的话，换行符会很棒。使用 Windows 7。

我在做

    for /f "tokens=*" %%g in ('dir /b /a:d "*"') do (
    forfiles /m *.mdb /c "cmd /c echo @fname>>output.csv"
    )

Answer 1

假设每个文件夹只有一个.mdb，并且您不想处理不存在.mdb 的文件夹：

echo off
setlocal enabledelayedexpansion
(
for /r %%d in (*.mdb) do (
  set first=yes
  set d=%%~pd
  for %%z in ("!d:\=.!") do set d=%%~xz
  <nul set /p =!d:.=!,%%~nd,
  for %%f in ("%%~pd\*.mpg") do (
    if defined first (
      echo %%~nf
      set "first="bre
    ) else (
      echo ,,%%~nf
    )
  )
  echo(
)
)>output.csv

带有解释的相同代码（在每一行下）：

@echo off
setlocal enabledelayedexpansion
(
REM enclose the whole code in parantheses ...<1>
for /r %%d in (*.mdb) do (
REM for every found .mdb file in folder or subfolders
REM /r = recursiv (including subfolders)
  set first=yes
  REM just a flag to identify the first line 
  set d=%%~pd
  REM get path of the file
  for %%z in ("!d:\=.!") do set d=%%~xz
  REM ugly code for getting the last element of the path
  REM by replacing \ with . so it looks like a filename
  REM %%~xz gets the "extension" of that fake-"file"
  <nul set /p =!d:.=!,%%~nd,
  REM using set /p trick to write a line without linefeed
  REM write the last path-element (with the dot removed) <comma> name of the mdb-file <comma>
  for %%f in ("%%~pd\*.mpg") do (
  REM for every .mpg in the found folder
    if defined first (
    REM if it is the first line (where the folder and the .mdb has to be written too)
      echo %%~nf
      REM append the name of the .mpg to the already written <folder>,<mdb-name>,
      set "first="bre
      REM delete the first-line-flag
    ) else (
      echo ,,%%~nf
      REM write a complete line
    )
  )
  echo(
  REM write the awesome linefeed
)
REM  <1>... to write it's complete output to a file
)>output.csv
