tdnf Commands

check: Checks for problems in installed and available packages for all enabled repositories. The command has no arguments. You can use --enablerepo and --disablerepo to control the repos used. Supported in Photon OS 2.0 (only).

check-local: This command resolves dependencies by using the local RPMs to help check RPMs for quality assurance before publishing them. To check RPMs with this command, you must create a local directory and place your RPMs in it. The command, which includes no options, takes the path to the local directory containing the RPMs as its argument. The command does not recursively parse directories. It checks the RPMs only in the directory that you specify. For example, after creating a directory named /tmp/myrpms and placing your RPMs in it, you can run the following command to check them:

tdnf check-local /tmp/myrpms
Checking all packages from: /tmp/myrpms
Found 10 packages
Check completed without issues

check-update: This command checks for updates to packages. It takes no arguments. The tdnf list updates command performs the same function. Here is an example of the check update command:

tdnf check-update
rpm-devel.x86_64 	4.11.2-8.ph1 	photon
yum.noarch      	3.4.3-3.ph1 	photon

clean: This command cleans up temporary files, data, and metadata. It takes the argument all. Example:

tdnf clean all
Cleaning repos: photon photon-extras photon-updates
Cleaning up everything

distro-sync: This command synchronizes the machine’s RPMs with the latest version of all the packages in the repository. The following is an abridged example:

tdnf distro-sync

downgrade: This command downgrades the package that you specify as an argument to the next lower package version. The following is an example:

tdnf downgrade boost

To downgrade to a version lower than the next one, you must specify it by name, epoch, version, and release, all properly hyphenated. The following is an example:

tdnf downgrade boost-1.56.0-2.ph1 

erase: This command removes the package that you specify as an argument.

To remove a package, run the following command:

tdnf erase pkgname

The following is an example:

tdnf erase vim

Total installed size: 1.94 M

You can also erase multiple packages:

tdnf erase docker cloud-init

info: This command displays information about packages. It can take the name of a package. Or it can take one of the following arguments: all, available, installed, extras, obsoletes, recent, upgrades. The following are examples:

tdnf info ruby
tdnf info obsoletes
tdnf info upgrades

install: This command takes the name of a package as its argument. It then installs the package and its dependencies.

To install a package, run the following command:

tdnf install pkgname

The following are examples:

tdnf install kubernetes

You can also install multiple packages:

tdnf install python-curses lsof audit gettext chkconfig ntsysv bindutils 
	 wget gawk irqbalance lvm2 cifs-utils c-ares distrib-compat

list: This command lists the packages of the package that you specify as the argument. The command can take one of the following arguments: all, available, installed, extras, obsoletes, recent, upgrades.

tdnf list updates

The list of packages might be long. To more easily view it, you can concatenate it into a text file, and then open the text file in a text editor:

tdnf list all > pkgs.txt
vi pkgs.txt

To list enabled repositories, run the following command:

tdnf repolist

makecache: This command updates the cached binary metadata for all known repositories. The following is an example:

tdnf makecache
Refreshing metadata for: 'VMware Lightwave 1.0(x86_64)'
Refreshing metadata for: 'VMware Photon Linux 1.0(x86_64)Updates'
Refreshing metadata for: 'VMware Photon Extras 1.0(x86_64)'
Refreshing metadata for: 'VMware Photon Linux 1.0(x86_64)'
Metadata cache created.

provides: This command finds the packages that provide the package that you supply as an argument. The following is an example:

tdnf provides docker
docker-1.11.0-1.ph1.x86_64 : Docker
Repo     : photon
docker-1.11.0-1.ph1.x86_64 : Docker
Repo     : @System

reinstall: This command reinstalls the packages that you specify. If some packages are unavailable or not installed, the command fails. The following is an example:

tdnf reinstall docker kubernetes

Reinstalling:
kubernetes                            x86_64        1.1.8-1.ph1             152.95 M
docker                                x86_64        1.11.0-1.ph1             57.20 M

Total installed size: 210.15 M

remove: This command removes a package. When removing a package, tdnf by default also removes dependencies that are no longer used if they were was installed by tdnf as a dependency without being explicitly requested by a user. You can modify the dependency removal by changing the clean_requirements_on_remove option in /etc/tdnf/tdnf.conf to false.

tdnf remove packagename

search: This command searches for the attributes of packages. The argument can be the names of packages. The following is an example:

tdnf search docker kubernetes
docker : Docker
docker : Docker
docker-debuginfo : Debug information for package docker
docker : Docker
kubernetes : Kubernetes cluster management
kubernetes : Kubernetes cluster management
kubernetes-debuginfo : Debug information for package kubernetes
kubernetes : Kubernetes cluster management

The argument of the search command can also be a keyword or a combination of keywords and packages:

tdnf search terminal bash
rubygem-terminal-table : Simple, feature rich ascii table generation library
ncurses : Libraries for terminal handling of character screens
mingetty : A minimal getty program for virtual terminals
ncurses : Libraries for terminal handling of character screens
ncurses : Libraries for terminal handling of character screens
bash : Bourne-Again SHell
bash-lang : Additional language files for bash
bash-lang : Additional language files for bash
bash : Bourne-Again SHell
bash-debuginfo : Debug information for package bash
bash : Bourne-Again SHell
bash-lang : Additional language files for bash

updateinfo: This command displays security advisories about packages. The following is an example:

tdnf updateinfo info

upgrade: This command upgrades the package or packages that you specify to an available higher version that tdnf can resolve. If the package is already the latest version, the command returns Nothing to do. The following is an example:

tdnf upgrade boost

Upgrading:
boost                                 x86_64        1.60.0-1.ph1              8.11 M

Complete!

You can also run the upgrade command with the refresh option to update the cached metadata with the latest information from the repositories. The following example refreshes the metadata and then checks for a new version of tdnf but does not find one, so tdnf takes no action:

tdnf upgrade tdnf --refresh
Refreshing metadata for: 'VMware Lightwave 1.0(x86_64)'
Refreshing metadata for: 'VMware Photon Linux 1.0(x86_64)Updates'
Refreshing metadata for: 'VMware Photon Extras 1.0(x86_64)'
Refreshing metadata for: 'VMware Photon Linux 1.0(x86_64)'
Nothing to do.

upgrade-to: This command upgrades to the version of the package that you specify. The following is an example:

tdnf upgrade-to ruby2.3

The commands and options of tdnf are a subset of those of dnf. For more help with tdnf commands, see the DNF documentation.
