but the command name doesn't necessarily need to match the package
name from whence it came, as in:
$ rpm -qf /bin/ls
coreutils-6.9-12.fc8
obviously, this isn't a life-or-death issue but, given the frequency
with which people might want to check the version number of a command,
i am a bit surprised that there's no GNU-wide standard option
(--exactversion?) that just gives it to you.
did no one ever suggest such a thing? just curious.

p.s. one option is to just use rpm and queryformat, as in:
$ rpm -q --queryformat "%{VERSION}\n" $(rpm -qf $(which grep))
2.5.1
$
or something to that effect.
