It helps you find, install, update, and region software—all portion keeping way of dependencies and making definite your strategy stays organized.

Different Linux distributions (often called “distros”) usage antithetic bundle managers:

• APT (Advanced Package Tool): Used successful Debian-based distros which see Ubuntu, Linux Mint, and Pop!_OS.
• YUM/DNF: Found successful Red Hat-based distros similar Fedora, CentOS, and RHEL. DNF is the modern replacement for YUM.

sudo dnf check-update

To instal a bundle (like fastfetch):

sudo dnf install fastfetch

DNF besides handles dependencies good and volition punctual you earlier proceeding.

Pacman (Arch, Manjaro)

sudo pacman -Sy

Then, instal a bundle (like curl):

Removing Software via the Terminal

Sometimes you instal something, recognize you don’t request it, and privation to cleanable up. Here's however to region bundle cleanly with each bundle manager.

APT

To region a bundle but support its config files:

sudo apt region package-name

To region a bundle and its configuration files:

sudo apt purge package-name

To region each unneeded packages:

sudo apt autoremove

DNF

Removing bundle is straightforward:

sudo dnf region package-name

DNF handles dependencies automatically, truthful you don’t person to interest astir leftovers excessively much. But, you tin person it treble cheque and region thing that is nary longer needed:

sudo dnf autoremove

Pacman

To region a package:

sudo pacman -R package-name

APT:

sudo apt update
