DNF is a new RPM-based package manager that replaced YUM, as YUM was affected by some performance issues and inefficient dependency resolving methods.
Its CLI interface is pretty intuitive:
# dnf [options] <command> [<argument>]
Although you can check man dnf to have a close look at its manual here are the basics of DNF:
# dnf search <package_name> # dnf install <package_name> # dnf remove <package_name> # dnf upgrade [<package_name>]
And a quick look at groups management:
# dnf group install <group_name> # dnf group upgrade <group_name> # dnf group remove <group_name>
Now something more advanced (if you’re interested in playing around):
- If you have many repositories enabled or one is giving you troubles you probably want to list them:
dnf repolist all
- List packages filtering by category and optional wildcard:
dnf list [a_category_below] [optional_wildcard]
- all: every package in every repository
- installed: installed packages (more fyi: RPMDB)
- available: listed in repos but not installed
- extras: installed but from unknown repository
- upgrades: with an upgrade available (see obsoletes too)
eg. dnf list installed kernel* will list every installed kernel.
- DNF has some powerful history commands. Use:
# dnf history list
to list every transaction, and undo/redo/rollback/info to interact with it:
# dnf history undo <transaction_id>
