DNF

 

1. dnf command to install package and it’s dependencies

You can use this command to install the latest version of a package and its dependencies.

 dnf install package_name

2. dnf command to remove a package and its dependencies

To remove an installed package and its dependencies, you can use the following command.

# dnf remove package_name 

3. Update a package and its dependencies with dnf command

This command allows you to update any installed packages and their dependencies to the latest versions.

# dnf update package_name

You can use this command without any arguments to update every package on the system.

# dnf update

4. dnf command to upgrade a package and its dependencies

This command has similar function like update command, which is upgrading a package and its dependencies to the newest version.

# dnf upgrade package_name

Using this command without package as an argument upgrades all the installed packages on the system.

# dnf upgrade

5. dnf command to check available updates for installed rpms

You can check the updates available for the installed packages and their dependencies in your system.

# dnf check-update

6. List all the packages with dnf command

This commands lists all the packages (installed and available for installation) for RPM-based Linux distribution.

# dnf lsit

7. dnf command to get list of only installed packages

# dnf list installed

8. dnf command to search a package in available repositories

This command allows you to search a specific package by using the word. If the word matches with the name or summary of the package, it will print the result.

# dnf search [words]

9. dnf command to get list of specific package

You can also get the list of a specific package by passing the package name as an argument. But make sure you have the exact package name or else this command will not work and may return Error: No matching Packages to list

# dnf list package_name

10. Get information of package with dnf command

With this command, you can view the detailed information of every package available in the repositories. This command expects the exact package name.

# dnf info package_name

11. dnf command to reinstall a package and its dependencies

Sometimes, there may come errors when using a certain package. Instead of removing it and install again, you can directly reinstall a package and its dependencies.

# dnf reinstall package_name

12. dnf command to download package instead of installing

You can also download package instead of installing it in the system. To do so, you can use --downloadonly option and you can specify the download directory using --downloaddir=<DIR_PATH> option.

# dnf install package_name --downloadonly --downloaddir=DIR_PATH

13. List currently enabled repositories with dnf command

To print the list of all enabled repositories, you can use the following command.

# dnf repolist

OR

# dnf repolist enabled

14. List currently disabled repositories with dnf command

To get the list of all disabled repositories, you can use the disabled option.

# dnf repolist disabled

15. dnf command to list all repositories

You can also list all the repositories that are configured on your system.

# dnf repolist all

16. Enable specific repository for runtime execution with dnf command

You can install a package from a specific repository using --enablerepo option. It can also enable a disabled repository to install a package.

# dnf install package_name --enablerepo=repo_name

OR

You can disable all the repositories and use only a single repository using:

# dnf install package_name -disablerepo=* --enablerepo=repo_name

For Example, I will install vsftpd package using appstream repo only and will disable all other repository.

17. Disable specific repository for runtime execution with dnf command

--disablerepo allows you to disable repository for runtime execution. It restricts the dnf to install a package from that repository. If the package is not available in other enabled repositories, you may not be able to install the package.

# yum install package_name --disablerepo=repo_name

For example, here I was having some issues with appstream repo so I have temporarily disabled it for this command and using other repos to install the package. But you should know that this command will only work if the provided package is part of a different repository. If any of the dependent package are part of the disabled repo, then the package installation will fail.

18. Find which rpm package provides a specific file

You can use this command to find out which packages contain a specific file.

# dnf provides file_name

OR

# dnf whatprovides file_name

 

For Example, let us try to find the rpm which provides us the python3 binary:

dnf provides python3

To get the complete list of files by the name python3, you can use regex with dnf command.

dnf provides */python3

19. List package’s dependencies and what packages provide them

# dnf deplist package_name

For Example, to get the list of dependent rpms required to install nmap package we can use the following command:

dnf deplist nmap

20. List all group packages with dnf command

Group package is the collection of multiple packages in a certain group. You can use the following command to list all the available groups for your system.

# dnf grouplist

21. dnf command to install a group package

When you install a group package, all the packages inside the group will be installed. To install a group package, you can use this command.

# dnf install group_package

22. dnf command to remove group package

# dnf remove group_package

23. Update a group package using dnf command

To update an installed group package in your system, you can use this command.

# update groupupdate group_package

24. View the history of all dnf commands executed in the node

You can use this command to view the information of what has happened in the past execution of dnf command.

# dnf history

25. dnf command to undo and redo changes

You can undo and redo the changes made by dnf command execution. You will need a transaction id which you can get from history command.

To undo the change, you can use:

# dnf undo transaction_id

To redo the change, you can use:

# dnf history redo transaction_id

26. dnf command to undo all the transactions after the specified transaction

You can also use rollback command with dnf to undo all the transactions after the specified transactions. For example, if you have 15 transactions in the history and you specify the transaction id 10, it will undo all the transactions after 10 i.e. 11, 12, 13, 14, 15.

# dnf hisroty rollback transaction_id

27. dnf command to clean all the caches

To remove all the caches stored by dnf, you can use the following command.

You can use the interactive dnf shell where you can execute all of the dnf commands.

# dnf shell
