String replace in all files

[david1337]

Hi guys

With this script I can replace the word "oldtext" with "newtext" for the file test.txt.

$szFile = "test.txt"

$szText = FileRead($szFile,FileGetSize($szFile))


$szText = StringReplace($szText, "oldtext", "newtext")

FileDelete($szFile)
FileWrite($szFile,$szText)

 

But how can I do this for ALL *.txt files in the folder?
I tried with *.txt instead of test.txt, but this just deletes all the txt files.

All *.txt files in the same directory?

hi water

Yeah, how can I change oldtext to newtext for all txt files in the same directory?

_FileListToArray returns an array with all *.txt files. Put your current code into a function and call it for each element of the array.

BTW:
To enhance performance use

$szText = FileRead($szFile)

because as default the function reads the whole file.

How do I call it for each element in my array?

 

#include <Array.au3>
#include <File.au3>



; List all the files and folders in the desktop directory using the default parameters.
Local $szFile = _FileListToArray(@ScriptDir, "*.txt")


Call("Replace")


Func Replace()
$szText = FileRead($szFile)


$szText = StringReplace($szText, "old text", "new text")

FileDelete($szFile)
FileWrite($szFile,$szText)
EndFunc

Something like this.
But you definitely need to learn how Autoit works. Especially arrays. There are very good tutorials in the wiki

#include <File.au3>
; List all the files in the directory
Local $aFileList = _FileListToArray(@ScriptDir, "*.txt")
For $i = 1 To $aFileList[0]
    Replace($aFileList[$i])
Next

Func Replace($sFile)
    $sText = FileRead($sFile)
    $sText = StringReplace($sText, "old text", "new text")
    FileDelete($sFile)
    FileWrite($sFile, $sText)
EndFunc   ;==>Replace

Thanks water!

That worked perfectly.
Yes you are absolutely right. I really am a newb when it comes to arrays

I'll start with understanding the one you just wrote for me here.

Once again, thanks for the help. It's much appreciated.
