command-line - Batch File Replace Extracted File

Question

I have a .bat file that unzips a kml from a kmz. If I run the batch file again it prompts me if I want to replace the file. Is there away I can have it always replace the file without prompting the user or displaying a cmd window?

    @echo off
    md tempKml
    cd tempKml
    ..\unzip ..\%1 >nul 
    cd ..
    dir tempKml\*.kml /s/b

Answer 1

Use the -o option?

..\unzip -o ..\%1 >nul
