VBScript to remove (delete) string from a text file.

I have the "replace.vbs" file saved to C:\Windows.
I use it to find and replace strings in text files.

Command line Syntax:

replace.vbs OLDSTRING NEWSTRING C:\file.txt


How can I modify the replace.vbs script to delete
the string rather than replace it with another string?

I have very little scripting knowledge so I would really
appreciate help with this.

replace.vbs

Dim FileName, Find, ReplaceWith, FileContents, dFileContents  
 Find         = WScript.Arguments(0)  
 ReplaceWith  = WScript.Arguments(1)  
 FileName     = WScript.Arguments(2)  
 
 FileContents = GetFile(FileName)  
 
 dFileContents = replace(FileContents, Find, ReplaceWith, 1, -1, 1)  
 
 if dFileContents <> FileContents Then  
 WriteFile FileName, dFileContents  
 End If  
 
 function GetFile(FileName)  
 If FileName<>"" Then  
 Dim FS, FileStream  
 Set FS = CreateObject("Scripting.FileSystemObject")  
 on error resume Next  
 Set FileStream = FS.OpenTextFile(FileName)  
 GetFile = FileStream.ReadAll  
 End If  
 End Function  
 
 function WriteFile(FileName, Contents)  
 Dim OutStream, FS  
 
 on error resume Next  
 Set FS = CreateObject("Scripting.FileSystemObject")  
 Set OutStream = FS.OpenTextFile(FileName, 2, True)  
 OutStream.Write Contents  
 End Function  
 

Deleting a particular string is the same as replacing it with the empty string (""), so there's no need to change the script.

If you want to change the script anyway, change these two lines

ReplaceWith  = WScript.Arguments(1)
FileName     = WScript.Arguments(2)

into this:

ReplaceWith  = ""
FileName     = WScript.Arguments(1)

Thanks the "" in the command line works great!
 

 replace.vbs OLDSTRING "" C:\file.txt 

You're welcome.
