Hi!

I installed Red Hat Linux 9 with "Everything" Installation.
So it was approximatelly 5GB
Where can I find now the description of all the applications,
packages, libraries that I installed?
For sure the set in main menu are only some of them
Especially I am interested in compilers, C++ libraries,
applications for numerical computations

Thanks!

There's probably a graphical tool to do this. I can tell you console commands.

To see all packages you have run
rpm -qa
Warning: the list will be long! If you want to have it in a file so you can read/browse it later use something like
rpm -qa >filename

When you have a list of packages, you can read description using
rpm -qi packagename

You can also use
rpm -qai
It'll show descriptiuons of all packages. Big warning: much longer than the package list, try not to use

The compiler you have in your system is gcc (g++ for C++). To see all gcc-related packages run
rpm -qa|grep gcc
(you can filter for different names this way)

Libraries - all packages with names beginning with lib. You probably have more than 100, so when you need something rather first google for a library name for the task and later see if you have it installed...

Thanks! The only thing with rpm -qa all the packages in the list are mixed
Can it produce the list where the packages are grouped according to their purposes?

Probably yes, but the command will be more compilicated.

BTW I've found a graphical tool that would be much easier for the task. RH manual chapter: http://www.redhat.com/docs/manuals/l...hical-rpm.html

You could just go to the Add/Remove Programs tool from the Preferences menu. The applications there are grouped by category, and if you open the category up to see the programs, there is a short description next to them.

A little unprofessional, but hey =)

Hope it helped

No, there not all packages are listed
