Download, Store and Install Packages in Ubuntu Automaticly

I normaly like to have the packages I install stored, to use later on. This is helpfull you don't have an internet conection or have a slow one, or need to install the same stuff on multiple machine.

So I have made a couple off scripts in bash language, which I had never used before, so these migth no be the best scripts in the world but they get the jobe done.

The first script (download_and_store) to download and store in folders all of my favorite apps, and another that installs every apps (install_all) on those folders.


download_and_store
--------------------------------------------------------------------------------------------------

#!/bin/bash

## List of packages to download ####
L_PACKAGES_TO_DOWNLOAD="

vlc
mplayer
amarok
wireshark
k3b

"
################################

D_APTGET_CACHE="/var/cache/apt/archives"

echo "Where will you want to store the packages"
read D_DOWNLOADED_PACKAGES

# clean apt-get's cache
apt-get clean

# create the root directory for the downloaded package ##
mkdir -p $D_DOWNLOADED_PACKAGES


for i in $L_PACKAGES_TO_DOWNLOAD ; do ## go through all the packages on the list

## download apt-get packages whithout instaling them (apt-get cache) ##
apt-get install -d $i

## create the dir for the downloaded package ##
mkdir $D_DOWNLOADED_PACKAGES/$i

## move de downloaded package on apt-get chache to the created dir ##
mv $D_APTGET_CACHE/*.deb $D_DOWNLOADED_PACKAGES/$i

# clean apt-get's cache
apt-get clean

done


install_all
----------------------------------------------------------------------

#!/bin/bash
for i in $( ls -p | grep "/" ); do ## go through every dir
echo ">>>>>>>>>>>>>>>>>>>>>"
cd $i ## enter a dir (where the packages and dependecies are)
echo Dir Actual: $(pwd)
dpkg -i *.deb ## install all debs (package and its dependencies)
cd ..
echo "<<<<<<<<<<<<<<<<<<<<<" done


Now for the demonstration, lets use download_and_store to download all of you favorite apps.

# create a file for download_and_store #####
$ sudo gedit download_and_store

paste the script above, and change the list L_PACKAGES_TO_DOWNLOAD, to include you favorite packages (these are separeted by a space or newline).

# give the script permitions to execute #####
$ sudo chmod 777 /path_to_it/download_and_store

# execute download_and_store
$ cd /path_to_it
$ ./download_and_store
Where will you want to store the packages
/home/my_user/Desktop/saved_apps --> you chose this dir

Now just wait...

Once its over you will have in /home/my_user/Desktop/saved_apps a folder for each application, for example vlc, you wil have a dir named vlc whith the vlc package and all of it's dependencies.

============================
Now, lets use install_all to install all of your downloaded apps.

# create a file for install_all #####
$ sudo gedit /home/my_user/Desktop/saved_apps/install_all

as you can see install_all must be in the root dir you inputed earlier ( /home/my_user/Desktop/saved_apps), this script will install all he can find in the dirs below.

# give the script permitions to execute #####
$ sudo chmod 777 /home/my_user/Desktop/saved_apps/install_all

# execute download_and_store
$ cd /home/my_user/Desktop/saved_apps/
$ ./install_all

Now wait...

There you apps should all be installed.

These scripts are very basic, these are my first in bash programing, and aren't fully tested, but if you can get an idea from them, or even improve them I'm happy.
