Identify the component of a Linux distribution that a file belongs to

Discovering which package installed a specific file on your Linux system is invaluable when you need to restore default configurations after unintended edits. In this guide, we’ll explore DNF-based commands to:

Find the package providing a file or command
List all files in a package
Filter package file listings

These examples assume a DNF-based distribution (Fedora, RHEL, CentOS Stream). On older systems using yum, substitute yum provides and yum repoquery.

Table of Common DNF Queries

Command	Purpose	Example
`dnf provides <file>`	Identify package owning a file	`dnf provides /etc/anacrontab`
`dnf provides <command>`	Find package that supplies a CLI command	`dnf provides docker`
`dnf repoquery --list <pkg>`	List every file in any package	`dnf repoquery --list nginx`
`dnf repoquery --list <pkg> \| grep <pattern>`	Filter listed files by name or extension	`…	grep ‘.conf’`

1. Find Which Package Owns a File

Suppose you’ve modified /etc/anacrontab and want to revert it to the distribution’s original version. Use:

$ dnf provides /etc/anacrontab
cronie-anacron-1.5.2-4.el8.x86_64 : Utility for running regular jobs
Repo        : baseos
Matched from:
Filename    : /etc/anacrontab

cronie-anacron-1.5.2-6.el8.x86_64 : Utility for running regular jobs
Repo        : @system
Matched from:
Filename    : /etc/anacrontab

The output shows cronie-anacron as the provider. To restore:

$ sudo rm /etc/anacrontab
$ sudo dnf install --refresh cronie-anacron

After reinstalling, the original /etc/anacrontab is back in place.

Removing system files can affect service behavior. Always backup configurations before deletion.

2. Discover Which Package Supplies a Command

Want the docker CLI but unsure which package includes it? Run:

$ dnf provides docker
podman-docker-3.1.0-0.13.module_el8.5.0+733+9bb5dffa.noarch : Emulate Docker CLI
Repo        : appstream
Matched from:
Provide     : docker = 3.1.0-0.13.module_el8.5.0+733+9bb5dffa

podman-docker-3.3.0-0.17.module_el8.5.0+874+6db8bee3.noarch : Emulate Docker CLI
Repo        : appstream
Matched from:
Provide     : docker = 3.3.0-0.17.module_el8.5.0+874+6db8bee3

Here, podman-docker emulates the Docker CLI, so install it to use docker.

3. List All Files in a Package

To inspect every file a package ships—even if it isn’t installed locally—use:

$ dnf repoquery --list nginx
/etc/logrotate.d/nginx
/etc/nginx/fastcgi.conf
/etc/nginx/fastcgi.conf.default
...
/usr/lib/.build-id

This complete list helps you identify configuration files, binaries, libraries, and other assets.

4. Filter the File Listing

Narrow down to specific file types (e.g., configuration files) by piping to grep:

$ dnf repoquery --list nginx | grep '\.conf'
/etc/nginx/fastcgi.conf
/etc/nginx/fastcgi.conf.default
/etc/nginx/nginx.conf
/etc/nginx/nginx.conf.default

Use any regex pattern to quickly locate files of interest.
