Here at Bobcares, we use these commands often as a part of our Server Management Services.

In this article, we will see the commands to list all software, list the number of packages installed, and search for a specific package.Īlso, we will add installed software on a text file, and later install the software from the text file. For example, command above returns packages from extras repo, which we installed the epel-release package, and from Software Collection repo, which has “epel” string in their release. The downsize of this method is that packages from other repos may also be listed if they have something that matches the string of repo been search. You can also specify the name of the package to search for instead of repo name. With this info, we can grep all packages installed by a particular repo: yum list installed | grep package_nameįor example, to look for all packages installed by EPEL repo: yum list installed | grep epel

Some repos also append a unique “repo” tag to the release. In the newer version of YUM, the repository which installed the package is listed together.

“list yum installed” is a popular command to list all installed packages on the system.
