# apt-offline2bat.sh

This script is used to creat an batch script for downloading all needed files and packages needed by **apt-offline**. The created batch script will need curl and zip to be installed on windows. 

As curl is mandatory for the script, zip is not. It is possible to edit the created batch script and delete the last four lines of the script. You can compress the files with the application of your choice.

    zip ..\bundle.zip *
    cd ..
    del bundle\*.* /Q
    rmdir bundle

# Usage of apt-offline

Apt-Offline is an offline download helper to updateing debian based linux distributions. It should be possible to install apt-offline via `apt install apt-offline`.

## Update packages database

The following two commands will create at first the `apt-offline.sig` file and at second the `apt-offline.bat` file to be run on the windows mashine.

    apt-offline set --update apt-offline.sig
    apt-offline2bat.sh apt-offline.sig apt-offline.bat
    
After the `bundle.zip` file is created and copied to the offline linux system, you can install the files.

    apt-offline install bundle.zip

## Update the system

We create again the `apt-offline.sig` file and `apt-offline.cmd` file to download the needed data. If only an upgrade is needed, change the upgrade-type to upgrade.

    apt-offline set --upgrade --upgrade-type=dist-upgrade apt-offline.sig
    apt-offline2bat.sh apt-offline.sig apt-offline.bat

Run the batch script and copy the `bundle.zip` file to the offline system. After this is done install the `bundle.zip` file and upgrade the system.

    apt-offline install bundle.zip
    apt dist-upgrade

## Install packages

Run the commands.

    apt-offline set --install-packages PACKAGE1 PACKAGE2 ... --update apt-offline.sig
