Chapter 3. Searching for RHEL content

Procedure

• Depending on your scenario, use one of the following options to search the repository:

  • To search for a term in the name or summary of packages, enter:

    $ dnf search <term>

    Copy to Clipboard

  • To search for a term in the name, summary, or description of packages, enter:

    $ dnf search --all <term>

    Copy to Clipboard

    Note that searching additionally in the description by using the --all option is slower than a normal search operation.

  • To search for a package name and list the package name and its version in the output, enter:

    $ dnf repoquery <package_name>

    Copy to Clipboard

  • To search for which package provides a file, specify the file name or the path to the file:

    $ dnf provides <file_name>

    Copy to Clipboard

Procedure

• List the latest versions of all available packages, including architectures, version numbers, and the repository they where installed from:

  $ dnf list --all
  ...
  postgresql.x86_64            16.4-1.el10      rhel-AppStream
  postgresql-contrib.x86_64    16.4-1.el10      rhel-AppStream
  postgresql-docs.x86_64       16.4-1.el10      rhel-AppStream
  postgresql-jdbc.noarch       42.7.1-6.el10    rhel-AppStream
  ...

  Copy to Clipboard

  The @ sign in front of a repository indicates that the package in this line is currently installed.

  Alternatively, to display all available packages, including version numbers and architectures, enter:

  $ dnf repoquery
  ...
  postgresql-0:16.4-1.el10.x86_64
  postgresql-contrib-0:16.4-1.el10.x86_64
  postgresql-docs-0:16.4-1.el10.x86_64
  postgresql-jdbc-0:42.7.1-6.el10.noarch
  postgresql-odbc-0:16.00.0000-4.el10.x86_64
  ...

  Copy to Clipboard

  Optionally, you can filter the output by using other options instead of --all, for example:

  • Use --installed to list only installed packages.
  • Use --available to list all available packages.
  • Use --upgrades to list packages for which newer versions are available.
  Note

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

• Version
• Release
• Architecture
• Package size
• Description

Procedure

• Display information about one or more available packages:

  $ dnf info <package_name>

  Copy to Clipboard

  This command displays the information for the currently installed package and, if available, its newer versions that are in the repository. Alternatively, use the following command to display the information for all packages with the specified name in the repository:

  $ dnf repoquery --info <package_name>

  Copy to Clipboard
  Note

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

Procedure

• Use one of the following methods if you use global expressions in dnf commands:

  • Enclose the entire global expression in single or double quotation marks:

    # dnf provides "*/<file_name>"

    Copy to Clipboard

    Note that you must precede <file_name> either by / for an absolute path or */ to use a wildcard if the full path is unknown.

  • Escape the wildcard characters by preceding them with a backslash (\) character:

    # dnf provides \*/<file_name>
