如何批量合并PDF文档

发布于 2024-11-30 01:51:05 字数 489 浏览 1 评论 0原文

我正在寻找一个批处理文件或一个 vbscript，它将像 pdf 文件名一样合并。应该合并的文件将具有相同的文件名，直到第一个“.”。我的整个文件夹包含大约 4000 个文件。文件扩展名符合以下格式

1111111111111111.22222222.pdf ==> 1是0-9的任意16个数字，2是0-9的任意8个数字

我想以批处理方式合并文件夹中的类似文件。直到第一个文件名相同的所有文件都应合并为“.”。

示例： 1111111111111111.25484686.pdf 应与 1111111111111111.54874568 合并，而 5555555555555555.78468767 应与 5555555555555555.48687654 合并5555555555555555.68974582

文件可以输出到另一个文件夹，但这不是必需的。输出后的新文件名也没关系，只要能用就行。

我知道有软件可以处理这个问题，但是拖放所有类似的文件来合并它们会花费很长时间。

Google 搜索发现 http://www.pdfsam.org/ - 一个提供免费 PDF 合并实用程序的网站具有命令行界面（以及 GUI）。我不知道这有多好用。确保您获得的是该网站提供的免费实用程序，而不是同一网站上宣传的竞争对手的解决方案。

还有许多其他实用程序，其中大多数都是收费的。

一旦您弄清楚如何使用所选实用程序的命令行界面，您就可以使用如下所示的批处理文件来动态构建要合并的文件列表。（此批处理代码未经测试。这个概念肯定会起作用，但可能需要一些调试）

@echo off
setlocal enableDelayedExpansion

:: This initial loop determines which files need to be merged
:: and then calls :merge for each unique set of files. This top
:: loop should work no matter what utility you choose.
set "current="
set cnt=0
:: for current directory, LOC should be empty (or .\)
:: for any other path, LOC should include \ at end
set "LOC="
for %%F in ("%LOC%*.*.pdf") do (
  for /f "tokens=1,* delims=." %%A in ("%%~nF") do (
    if "%%A" neq "!current!" (
      if defined current call :merge
      set cnt=0
      set current=%%A
    )
    set /a cnt+=1
    set pdf.!cnt!=%%~fF
  )
exit /b

A Google search found http://www.pdfsam.org/ - a site that offers a free PDF merge utility that has a command line interface (as well as a GUI). I have no idea how well this works. Make sure you get the free utility offered by this site and not the competitor's solution that is advertised on the same site.

There are many other utilities out there, most of them for a fee.

Once you figure out how to use the command line interface of your utility of choice, you can use a batch file like the one below to dynamically build your list of files to merge. (This batch code is untested. The concept will definitely work, but it may need some debugging)

@echo off
setlocal enableDelayedExpansion

:: This initial loop determines which files need to be merged
:: and then calls :merge for each unique set of files. This top
:: loop should work no matter what utility you choose.
set "current="
set cnt=0
:: for current directory, LOC should be empty (or .\)
:: for any other path, LOC should include \ at end
set "LOC="
for %%F in ("%LOC%*.*.pdf") do (
  for /f "tokens=1,* delims=." %%A in ("%%~nF") do (
    if "%%A" neq "!current!" (
      if defined current call :merge
      set cnt=0
      set current=%%A
    )
    set /a cnt+=1
    set pdf.!cnt!=%%~fF
  )
exit /b


:merge
:: This routine should build the command line to merge the current
:: file list contained in pdf.1 through pdf.!cnt!
::

::
  set "list="
  for /l %%N in (1 1 !cnt!) do set list=!list! -f "!pdf.%%N!"
::
::
:: The rest is up to you!
::
exit /b
