yum - basics
yum – Red Hat tool for RPM package management used to download, install update, erase or list info about system packages
/etc/yum.repos.d/ -> list of configured repositories (web or ftp sites) that will be searched to download and install RPM packages
To view which repositories you have enabled:
yum repolist enabled
repo id -> repo name -> status
InstallMedia -> Fedora 8 -> enabled
fedora -> Fedora 8 – x86_64 -> enabled
updates -> Fedora 8 – x86_64 – Updates -> enabled
Working with yum:
yum install <package_name> -> will search, download and install requested package (e.g.: yum install gcc)
yum update -> will search for available updates and install them to your system
yum check-update -> will look for available updates for your system
yum upgrade -> similar to yum update, but tries to upgrade all your obsolete packages
yum remove (or erase) <packge_name> -> will remove previously installed package and its dependencies (e.g.: yum remove gcc)
yum search <package_name> -> search for package descriptions
yum clean packages -> cleans yum cache in /var/cache/yum/…
yum info <package_name> -> displays info about requested package (similar to rpm -qi) (e.g.: yum info gcc)
For complete options see man page
