Hi, for work im trying to create a batch file that edits 2 files Definfo.dat and Usage.dat in the following manner. The file definfo.dat contains the following lines [Curdefs]=20080718.003 [Lastdefs]=20080717.025 I need the batch file to change the value in [Curdefs]=20080718.003 to 20080717.025 as in [Lastdefs] Also it needs it to check Usage.dat to see if the value 20080718.003 exists and to change it to 20080717.025. The values shown here are just examples and can change from on PC to another

" The values shown here are just examples and can change from on PC to another " So, to generalize, you need to change the [Curdefs]= value to the [Lastdefs]= value, right? ===================================== If at first you don't succeed, you're about average. M2

Correct

here's a vbscript Set objFS = CreateObject("Scripting.FileSystemObject") Const ForReading = 1 Set objFile = objFS.OpenTextFile("c:\test\test.txt", ForReading, True) ReadAllTextFile = objFile.ReadAll arrAll = Split(ReadAllTextFile,vbCrLf) For i = LBound(arrAll) To UBound(arrAll) If InStr(arrAll(i),"Lastdefs") > 0 Then arrLastDef = Split(arrAll(i),"=") arrCurDef = Split(arrAll(i-1),"=") arrCurDef(1)=arrLastDef(1) arrCurDef = Join(arrCurDef,"=") arrAll(i-1) = arrCurDef End If Next For i = LBound(arrAll) To UBound(arrAll) WScript.Echo arrAll(i) Next save the above as script.vbs and on command line c:\test> cscript /nologo script.vbs
