I thought of a couple other things.
debian's package manager has a command recipe
dpkg -l [pattern]
which gives a nice tabulated 1-line output for installed packages
Name .. Version .. Description
(I wonder if there might even be a way to get a (_big_) list
like this of available packages .. deb-gurus: ..?)
I haven't found an exact command like that in yum/rpm, but you can
compose an rpm query to report any custom output -- in this case, like
rpm -qa --queryformat="%-20{NAME} %-15{version} %{SUMMARY}\n" [pat]
and it will do about the same as the dpkg example .. et voilà!
(It's possible there is a stock command or option to do this,
and I just haven't discovered it, of course.)
==> Aha! : discovery/side note:
rpm -q package-name
does *NOT* take wildcards :-(
but a query with a --queryformat spec seems like it *DOES* Yay! :-)
Ahhh <sigh type="relief">, that relieves a longstanding gripe. I have
always thought the recipe
rpm -qa | grep pattern
was ugly, so now I have a better way!
(Lan, you listening)
Now getting back to the original question, try this
alias rpmlist='rpm -qa --queryformat="%-30{NAME} %-15{version}
%{SUMMARY}\n"'
(mind the line wrap that may get into the email)
On my fc7 desktop system, this gives me a nice 2227-line summary. What
do you have in _your_ rpmlist?
