If you have a older version of a package, use ‘yum update package’ to upgrade it to the latest current version. Upgrade an existing package using yum update
To remove a package (along with all its dependencies), use ‘yum remove package’ as shown below. If you want yum to install automatically without prompting, use -y option as shown below. Installing : postgresql-9.0.86_64 2/2īy default ‘yum install’, will prompt you to accept or decline before installing the packages. The following example installs postgresql package. This will also identify the dependencies automatically and install them. To install a package, do ‘yum install packagename’. This article explains 15 most frequently used yum commands with examples.
Yum stands for Yellowdog Updater Modified. On some Linux distributions, yum is the default package manager. For example, apt-get, dpkg, rpm, yum, etc. Most of the Linux distributions provides some kind of package manager utility.

I guess the only thing learned from my exercise here is to note that yum lists of packages in red (or other 'color') indicate either an update is available, are outdated or they are non-standard packages. I built the rpm for that from a F11 SRPM package (for F8). And a package that I built from source code, which fixed a non functional part from the standard issue rpm package, xfce4-sensors-plugin.Īnd then there's that grep package shown in green text. Some that are 'old', non-current packages, kmod-nvidia and kernel. Then there is the one of questionable origin, meaning, I don't exactly remember, gtk-aurora-engine. Then there are a few that come from non standard sources, the Livna repo items, lindvd, msttcorefonts. From my 'red' list, the bulk are packages that have updates awaiting them and that I have never updated since doing fresh install because I don't use them (FF version 2, Java other than Sun Java, all in my exclude= list). Seems there is more than just one 'cause' for the show in red text result. Reading this thread got me to thinking on that a bit harder and I came up with this: I too have occassionally seen a package displayed in red text when doing something with yum and wondered just what that was trying to tell me.
