This is an old post, but what the hell...

rpm -qf /path/to/some/application

(This only works for files installed by rpm, which will include the
entire base OS.)

I just use the -q switch and the short name of the application.
e.g. in my system:
rpm -q opera
returns
opera-7.11-20030515.1

That's only because the "opera" package is installed on your system.
If a particular application's basename isn't the same as a package
name, this won't work. For example ...

bash-2.05b$ rpm -q csh
package csh is not installed
bash-2.05b$ rpm -qf /bin/csh
tcsh-6.12-4

Most of the programs have the --version option.
Try gcc --version or vi --version
I hope that helps.
