If I generate a "Package Download Script" in Snyaptic can it be rn from a terminal window instead of Synaptic?

I'm asking because basically I find the "Command Line" to be more understandable in terms of installing programs/packages as compared to a "GUI" like "Synaptic" or any other "Graphical" programs. Aside from thermometer showing some indicator of progress (and not all that well) there's nothing on the screen that the command line doesn't tell me. A text representation of the D/L percentage and speed is all I need.

Are any alterations needed to run the script in a terminal. If I run a small "apt-get" script and serialize a group of installs I have to follow each install with &&

example below

sudo apt-get update && 
sudo apt-get upgrade && 
sudo apt-get install linux-generic && 
sudo apt-get install linux-headers-generic && 
sudo apt-get install linux-image-generic &&
sudo apt-get install jockey-kde &&
sudo apt-get install kde-full && 
sudo apt-get install cinnamon && 
sudo apt-get install vlc && 
sudo apt-get install hplip &&  
sudo apt-get install thunderbird && 
sudo apt-get install libreoffice && 
sudo apt-get install sound-juicer && 
sudo apt-get install mypaint && 
sudo apt-get install alien-arena &&
sudo apt-get install openarena && 
sudo apt-get install aptoncd && 
sudo apt-get install prboom && 
sudo apt-get install deja-dup && 
sudo apt-get install banshee &&
sudo apt-get install backintime-kde &&
sudo apt-get install clementine &&



Running a script like my example requires constantly re-entering the password and if enough packages are contained can't be run unattended. Oddly enough I can't hand-hold the whole process as if there's nothing else to do. 

Is the && at the end of each line also required to run a script? 

As always any/all help will appreciated.

Thank You
