There are a few basic ideas for ou for reference...one is there are a few websites that you should know..rpmfind.net and freshrpms.net both are good for red hat users....when you search on rpmfind just make sure oyu get the rpm file not src one...and the correct one for your system...in mine it is always highlighted...it would be called Red hat 9.0 under the sytem...also here are some basic commands...all in terminal
su -makes you root
rpm -i [file name] -makes it install
rpm -Uvh [file name]- make it update
yum check-update -checks up dates and list them for your system, use this instead of up2date
yum update -updates all the available packages
yum install -y [package name] -installs the packages with answering yse to all install questions the package name is obtained from the get update list
i think that is some of the basics.....i'll work on getting a few post to a large tutorial of commands for you but atm not spending much time on web, on vacation at whistler.
oh and fedoranews.org has some nice tutorials
