If you want the version information for PACKAGES, try "dpkg -l|grep
'^i'", though I'm not entirely certain what kind of notation is
"commonly used throughout linux".
Good thanks for that tip. That's just what I was looking for.
I guess one could nitpik what is actually the accepted notation but
maybe I should have said through linux (except debian).
I think you'll find that `pkg-version' is a very typical notion
when referencing a version for communication... maybe
pkg version
would be high on the list too.
whereas
aptitude versions xorg
=> ihA 1:7.6+9 testing 500
Is not. You don't even get the pkg name together with the version at
all so copy paste becomes copy edit paste.
wtopa@dj:~$ aptitude versions xorg
i 1:7.6+9 testing,unstable 990
wtopa@dj:~$ dpkg -l xorg

If you use the tools it looks fine to me.
Am I misunderstanding something here.

Part of the problem may be that many packages provide a number of
commands not equal to one. How would you propose finding the version of
a library or a documentation package?
I'm not sure what you mean there, but for example.. if you search a
pkg at:
http://packages.debian.org/squeeze/xorg-dev
It will show up with a version notation. So I'm thinking the OS must
have that information somewhere.
Surely there is a standard way to see version information at a glance
and be able to copy paste it to email or whatever in a couple of moves
instead of dinking around for 5/6 minutes to get it.
dpkg -l|grep '^i'
does that pretty nicely... thanks again.
