This is a couple of useful scripts to test downloaded files.

This approach is recommended when downloading huge amounts of data like when downloading Oracle R12 installations files.

In addition to testing the downloaded files also be sure to use a download manager.

The basic zip test command is:

$ unzip –t –qq {zipfile}

I made a Linux script for it named ziptest.sh:

#!/bin/bash
# ziptest.sh
SOURCE=/util/install/R12.1.1-32
if [ -z "$1" ]
then
    name="*.zip"
else
    name="$1.zip"
fi
for zipfile in $SOURCE/$name
do
    unzip -t -qq $zipfile
    if [ $? -eq 0 ]
    then
        echo -n "."
    else
        echo " "
    fi
done
echo " "

A similar script can be made for Windows names ziptest.cmd:

@echo off
rem ziptest.cmd {zipfilename}
set zipdir=..\R12.1.1-32
rem do all zip files unless arg received
set zipfile=*.zip
if [%1]==[] goto doit
   set zipfile=%1.zip
:doit
   set target=%zipdir%\%zipfile%
   for %%a in ( %target% ) do call ziptest_call %%a

As command line programming in windows isn’t great we need to call a subprogram names ziptest_call:

@echo off
rem ziptest_call.cmd {zipfile}
if [%1]==[] goto noarg
if not exist %1 goto nofile
:main
    unzip –t –qq %1
    if errorlevel 1 goto badfile
goto xit
:noarg
    echo ARG missing – use only with ziptest.cmd
goto xit
:nofile
    echo FILE %1 does not exist
goto xit
:badfile
    echo %1 BAD
goto xit
:xit

That should be it.

Be sure to update directory references for your own purpose.
