This script is used to download all dependencies of a list of linux (debian) packages so that they can be uploaded to an offline computer. The script will create a new directory named packages/, fetch all dependencies and save the remote URLs to a file in the directory, then download all .deb packages to the directory. Examples of usage below:
./get_depends.sh g++ gcc
./get_depends.sh linux-azure linux-base magic
You can then copy/move the packages/ directory to a storage device, plug in the device to the offline computer, then run sudo dpkg -i *.deb in packages/ in the offline computer to install all libraries.
Beware: in order to ensure all *.deb packages are downloaded, this script will delete all *.deb files in /var/cache/apt/archive. This should be harmless, but save the files somewhere else if you wish to preserve them.
