There is no search and replace function or stream editing at the command line in XP or 2k3 (dont know about vista or beyond). So, you'll need to use a script like the one Ghostdog posted, or a search and replace capable tool like sed.

There is more than one way to do it, as this script shows:

@echo off
    SETLOCAL=ENABLEDELAYEDEXPANSION

    rename text.file text.tmp
    for /f %%a in (text.tmp) do (
        set foo=%%a
        if !foo!==ex3 set foo=ex5
        echo !foo! >> text.file) 
del text.tmp

On a native Windows install  you can either use batch cmd exe  or vbscript without the need to get external tools  Here s an example in vbscript   Set objFS   CreateObject  Scripting FileSystemObject   strFile    c  test file txt  Set objFile   objFS OpenTextFile strFile  Do Until objFile AtEndOfStream     strLine   objFile ReadLine     If InStr strLine  ex3   gt  0 Then         strLine   Replace strLine  ex3   ex5       End If      WScript Echo strLine Loop       Save as myreplace vbs and on the command line   c  test gt  cscript  nologo myreplace vbs   gt  newfile c  test gt  ren newfile file txt

This is the kind of stuff sed was made for  of course  you need sed on your system for that      sed  s ex3 ex5 g  input txt   output txt  You will either need a Unix system or a Windows Cygwin kind of platform for this  There is also GnuWin32 for sed   GnuWin32 installation and usage
