How to get version information in common notation
How can I quickly get version information for packages I have
installed. I mean the common kind of notion used throughout linux.
Not the unusual non standard notation one gets with `apt-get versions',
which is not suitable for copy/paste:
,----
| aptitude versions xorg
| ihA 1:7.6+9 testing 500
`----
I mean like `pkg-version'
Or at least something like what X and many other packages will output:
X -version
X.Org X Server 1.11.1
But not all packages are so kind and not all use the same cmdline switch
so you end up wasting time trying a few or `man pkg' to see if it even
has such a flag.
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.
And how can I know at a glance which xserver[s] are in use? It appears
the original installation routine has installed a heard of them. 37 in
fact.
The list is posted at the end. And how can I tell quickly which are needed?
And which can be removed?
`ps wwaux|grep xserver-xorg'
Would seem to indicate that none are running... but of course with X and
kde running... that can't be the case.
