How to check which packages are installed? to remove them?

[Antonio Olivares]

Dear List,
   On one of my computers, System Settings ->
Add/Remove Applications is not working as it should. 
So I removed it within itself, now I cannot see which
packages are installed.  I know that the command(s)
have been discussed before but I probably deleted the
messages. rpm -??.  Is there a way via command line to
determine which packages are installed in the system
and how to remove them?

Also I would like to ask on how to remove
documentation from the system.  I need to know how
much space help/man pages occupies.  I need to free up
some space and want to know how to do it.

Regards,

Antonio

You do not see the irony within your writing? On the one hand you do not
have a look at the rpm man page (rpm --help can be useful too; not to
mention man yum) and on the other hand you want to remove documentation?

Please read first the documentation. When you know all from mind, you
then can go and remove it.

# rpm -qa

will list all of the RPM's that you have installed on your system.

I would respectfully suggest, however, that if you needed to ask this question 
-- a simple and straightforward one with an easy answer -- then perhaps 
removing the documentation from your computer would not be appropriate at 
this time.
