I see you have a different search string than has been mentioned before.
Is yours really what you use, or something typed from memory? The ones
I have tried didn't seem to give correct results.
It was from memory, and I was even right ;)
Let me explain, it's very simple:
~i - select all installed packages
~M - select all automatically installed packages
! - 'not' logical operator
You are obviously not interested in 'not-installed' packages so the only
possible combinations are
!~M~i
or
~i!~M
which will have the same effect (yes, I tested). Because you run this
into a shell the pattern has to be between quotes as some of those
characters ("!" I think) have special meanings.
In my original thinking, I was mentioning /etc/apt/, because I presumed
it was a safe place to leave such information. I'm sure there is such a
safe place, somewhere. You use ~/bak, which I might imitate, now that I
am aware of it, even if /etc/apt/ is also a safe place.
Aware of? I just created it ;) My philosophy is "keep things at their
default settings as much as possible". This also involves not spreading
unnecessary files across the entire filesystem, /home is the place for
that.
Now, the discussion has moved to how to query the packaging system to
get the most useful file of information. I'm still not sure what the
query string should be.
See above.

Andrei
