Tue Feb 15 10:21:08 EST 2011

If you learn how to use the tools...

rpm -q screen
screen-4.0.3-1.el5_4.1

So you have the package name along with the version number 4.0.3 and
the build number is 1, build environment is el5 (enterprise Linux v. 5
with patches to 4.1)

rpm -qi screen

Summary     : A screen manager that supports multiple logins on one terminal.
Description :
The screen utility allows you to have multiple logins on just one
terminal. Screen is useful for users who telnet into a machine or are
connected via a dumb terminal, but want to use more than just one
login.

Install the screen package if you need a screen manager that can
support multiple logins on one terminal.

The "i" is short for "info". Lots of useful info.

The "l" means "list" so you get a list of all the files installed by
the package.

rpm -q --whatprovides /etc/pam.d/screen
screen-4.0.3-1.el5_4.1

This is a great one! It let's you find the package name that installed
any file on the system (other than user stuff of course).

So rpm gives loads of info based on what is requested.
