Chapter 4. Searching for RHEL 9 content

Procedure

1. List all enabled repositories on your system:

   $ dnf repolist

   To display only certain repositories, append one of the following options to the command:

   • Append --disabled to list only disabled repositories.
   • Append --all to list both enabled and disabled repositories.

2. Optional: List additional information about the repositories:

   $ dnf repoinfo <repository_name>

   Note

   You can filter the results by using global expressions. For details, see Specifying global expressions in DNF input.

Procedure

1. List both installed and available groups:

   $ dnf group list

   Note that you can filter the results by appending the --installed and --available option to the dnf group list command. By using the --hidden option, you can display hidden groups in the output.

2. List mandatory, optional, and default packages contained in a particular group:

   $ dnf group info "<group_name>"

   Note

   You can filter the results by appending global expressions as arguments. For more details, see Specifying global expressions in DNF input.

3. Optional: View the number of installed and available groups:

   $ dnf group summary

Procedure

1. List the module information in one of the following ways:

   • List all available modules:

     $ dnf module list
     Name        Stream   Profiles                               Summary
     ...
     nodejs      18       common [d], development, minimal, s2i  Javascript runtime
     postgresql  15       client, server                         PostgreSQL server and client module
     ...
     Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

     Use the dnf module list <module_name> command to list the same information but only for a specific module.

   • Search for which module provides a certain package:

     $ dnf module provides <package_name>

     For example, to display which module and profiles provide the npm package, enter:

     # dnf module provides npm
     npm-1:8.19.2-1.18.10.0.3.module+el9.1.0+16866+0fab0697.x86_64
     Module   : nodejs:18:9010020221009220316:rhel9:x86_64
     Profiles : common development s2i
     Repo     : rhel-9-for-x86_64-appstream-rpms
     Summary  : Javascript runtime
     ...

2. Use one of these methods to list module details:

   • List all details about a module, including a description, list of all profiles, and a list of all packages the module provides:

     $ dnf module info <module_name>

     For example, to display details about the nodejs package, enter:

     $ dnf module info nodejs
     Name             : nodejs
     Stream           : 18
     Version          : 9010020221009220316
     Context          : rhel9
     Architecture     : x86_64
     Profiles         : common [d], development, minimal, s2i
     Default profiles : common
     Repo             : rhel-9-for-x86_64-appstream-rpms
     Summary          : Javascript runtime
     Description      : Node.js is a platform built on Chrome's JavaScript runtime...
     Requires         : platform:[el9]
     Artifacts        : nodejs-1:18.10.0-3.module+el9.1.0+16866+0fab0697.src
                      : nodejs-1:18.10.0-3.module+el9.1.0+16866+0fab0697.x86_64
                      : npm-1:8.19.2-1.18.10.0.3.module+el9.1.0+16866+0fab0697.x86_64
     ...

   • List which packages each module profile installs:

     $ dnf module info --profile <module_name>

     For example, to display this information for the nodejs module, enter:

     $ dnf module info --profile nodejs
     Name        : nodejs:18:9010020221009220316:rhel9:x86_64
     common      : nodejs
                 : npm
     development : nodejs
                 : nodejs-devel
                 : npm
     minimal     : nodejs
     s2i         : nodejs
                 : nodejs-nodemon
                 : npm
     ...
