I have added a package to extras-devel called "freemoe" which is a set of scripts I use which are handy. They all have the freemoe-* prefix, so you can just type "freemoe-" and hit <tab><tab> and you'll see all the scripts it installs.
Thanks.
I've seen -o dir::cache=/home/user/MyDocs/.apt-archive-cache in a lot of apt-get commands.
Normally, you can this in /et/apt.conf.d/42cache (or whatever)
Dir::Cache::archives=/home/user/MyDocs/.apt-archive-cache
And then it should be the default archive cache dir
