Search PDF files for specific word and delete them

6 posts in this topic

I have about 7000 PDF files that I need to go through and purge the ones with a specific word in them (Obsolete). Of course the PDF files are all compressed so a simple grep Obsolete will not work. If i use pdftotext, part of gnuwin32, I can convert the files to text and then perform the grep search. Some brief background this is a backup to the primary document repository so it will be run daily.

I looked on here last week and nothing jumped out and and said I have done that before. Below is what I have started, if someone has already done either what I am talking about, knows of a better way, please point me in the right direction.

This is what I have been working on so far:

$search = FileFindFirstFile("g:\test\*.pdf")

While 1

$file = FileFindNextFile($search)

If @error <> 1 Then

ConsoleWrite("c:\gnuwin32\bin\pdftotext.exe " & $file & " " & $file & ".txt" & @CRLF)

ConsoleWrite($file & @CRLF)

EndIf

WEnd

; Close the search handle

FileClose($search)

Your method is bad !

Try this Posted Image

#include <File.au3>

$search = FileFindFirstFile ( @DesktopDir & "\*.pdf") ;  "g:\test\*.pdf"
$_pdftotextPath = 'c:\gnuwin32\bin\pdftotext.exe'
$_OutPutFilepath = 'C:\file.txt'
_FileCreate ( $_OutPutFilepath )

While 1
    $file = FileFindNextFile ( $search )
    If @error Then ExitLoop
    ConsoleWrite ( '-->-- $file : ' & $file & @CRLF )
    $_RunWait = '"' & $_pdftotextPath & '" "' & @DesktopDir & '\' & $file & '" ' & $_OutPutFilepath
    ConsoleWrite ( '-->-- $_RunWait : ' & $_RunWait & @CRLF )
    RunWait ( $_RunWait, '', @SW_HIDE )
    ShellExecuteWait ( $_OutPutFilepath ) ; see the text content
    FileDelete ( $_OutPutFilepath )
WEnd

FileClose ( $search )

Edit : don't forget double quotes in paths.

... and in filenames! Better enclose the complete filepath in double quotes.

I forget the string to find in pdf text, now it's working like you want ! Posted Image

$search = FileFindFirstFile ( @DesktopDir & "\*.pdf") ;  "g:\test\*.pdf"
$_pdftotextPath = 'c:\gnuwin32\bin\pdftotext.exe'
$_OutPutFilepath = 'C:\file.txt'
_FileCreate ( $_OutPutFilepath )
$_StringToFind = 'DavidFromLafayette'

While 1
    $file = FileFindNextFile ( $search )
    If @error Then ExitLoop
    ConsoleWrite ( '-->-- $file : ' & $file & @CRLF )
    $_RunWait = '"' & $_pdftotextPath & '" "' & @DesktopDir & '\' & $file & '" ' & $_OutPutFilepath
    ConsoleWrite ( '-->-- $_RunWait : ' & $_RunWait & @CRLF )
    RunWait ( $_RunWait, '', @SW_HIDE )
    ShellExecuteWait ( $_OutPutFilepath ) ; see the text content
    $_RetVal = _ReplaceStringInFile ( $_OutPutFilepath, $_StringToFind, $_StringToFind )
    If Not @error And $_RetVal Then FileDelete ( @DesktopDir & '\' & $file )
    FileDelete ( $_OutPutFilepath )
WEnd

FileClose ( $search )

thanks for the help wakillon .

Below is what I ended up using to take care of the recursive directories.

#include <File.au3>

$current = "r:\updatecd\gcr_document"

$ext = "*.pdf"

$_pdftotextPath = 'c:\gnuwin32\bin\pdftotext.exe'

$_OutPutFilepath = 'C:\temp\file.txt'

_FileCreate($_OutPutFilepath)

Search($current, $ext)

Func Search($current, $ext)

Local $search = FileFindFirstFile($current & "\*.*")

While 1

Dim $file = FileFindNextFile($search)

If @error Or StringLen($file) < 1 Then ExitLoop

;ConsoleWrite('-->-- $file : ' & $file & @CRLF)

If Not StringInStr(FileGetAttrib($current & "\" & $file), "D") And ($file <> "." Or $file <> "..") Then

$_RunWait = '"' & $_pdftotextPath & '" "' & $current & '\' & $file & '" ' & $_OutPutFilepath

RunWait($_RunWait, '', @SW_HIDE)

$filecontents = FileRead($_OutPutFilepath)

$ObsoleteinFile = StringInStr($filecontents, "Obsolete")

If $ObsoleteinFile > 0 And $ObsoleteinFile < 100 Then ; check to ensure Obsolete is on title page

ConsoleWrite("Obsolete in File" & $file & $ObsoleteinFile & @CRLF)

FileDelete($current & '\' & $file)

EndIf

FileDelete($_OutPutFilepath)

EndIf

If StringInStr(FileGetAttrib($current & "\" & $file), "D") And ($file <> "." Or $file <> "..") Then

Search($current & "\" & $file, $ext)

EndIf

Sleep(1000)

WEnd

FileClose($search)

EndFunc ;==>Search
