I need a vbscript to compare a text file with a list of serial numbers as follows:

Textfile1
12345
23456
23457

and

Textfile2
12345
23456
etc...

If they are equal then exit
if they are Not equal then i will send and e-mail ( i have the e-mail script)

One list will be the constant, and the other will warn of changes.

Do you need to know what is the difference?
Do you need compare binary or as text ?
If it is as text, case sensitive or not,
Is trailing extra spaces are ok?

What the aprox. size ?
How do you want to see differences? line numbers? or copy of lines?

I am tracking hard drive serial numbers from raid servers.  There are only 5 -14 drives on each server.  Serial numbers are gathered using a utility like amcli.exe.  The txt report contains more that just serial numbers.  I will need to filter "Serial Number = XXXXXXXXXXXXX" and compare the numbers to a known list of serial numbers.  If a hard drive is removed or changed the script will report a difference between txt files and send an e-mail to admins.

Here you go...
=========================

Dim fso, f1,f2, file1, file2
Dim i,j, s, report
Dim found
Dim Diff1 , Diff2, report      
Dim d1,d2

File1="C:\text1.txt"
File2="C:\text2.txt"

set d1 =createObject("Scripting.Dictionary")
set d2 =createObject("Scripting.Dictionary")
Set fso = CreateObject("Scripting.FileSystemObject")
Set f1 = fso.OpenTextFile(file1, 1,0)
Set f2 = fso.OpenTextFile(file2, 1,0)


Do While f1.AtEndOfStream = False
      s = UCase(Trim(f1.ReadLine))

      if s <>"" then
            d1.Add d1.count,s
      end if
loop


Do While f2.AtEndOfStream = False
      s = UCase(Trim(f2.ReadLine))
      if s <>"" then
            d2.Add d2.count,s
      end if
loop

Diff1=""
Diff2=""
found = false
For i = 0 To d1.Count -1
      found = false
      For j = 0 to d2.Count-1
      
            if d1(i)= d2(j) then
                  found=true
                  exit for
            end if
      next
      if not found then
            diff1= diff1 + d1(i) + " "
      end if
next
found = false
For i = 0 To d2.Count -1
      found = false
      For j = 0 to d1.Count-1
      
            if d2(i)= d1(j) then
                  found=true
                  exit for
            end if
      next
      if not found then
            diff2= diff2 + d2(i) + " "
      end if
next

Report=""
if diff1<>"" then
      Report = "Found only in " & file1 & "  " & diff1
end if

if diff2<>"" then
      Report = Report & Chr(13) & chr(10) & "Found only in " & file2 & "  " & diff2
end if



if report="" then
      msgbox "No difference"
else
      msgbox report
end if

===================
I hope it helps.
