Installing Software in Linux

Linux software is usually installed through the distribution package manager. This is safer than downloading random installers because packages are tracked, updated and removed cleanly.

Debian and Ubuntu systems

sudo apt update
sudo apt install package-name

Red Hat, Fedora and similar systems

sudo dnf install package-name

Older Red Hat-based systems may use yum instead of dnf.

Check whether software is already installed

which command-name
command-name --version

Prefer the package manager where possible. It handles dependencies, updates and removal better than manual installation.
