22 - Red Hat Package Manager (RPM)

Concept

Let's use Remote Desktop Connection command as example -- sudo dnf install gnome-remote-desktop.

In Linux, final usable software is called package.
Think Red Hat Package Manager (RPM) like an installer file, it contains all dependencies, script to install and configuration info.
dnf is a tool to run the installer (RPM).

Tutorial

View RPM Content In Local Without Extracts It

Find RPM file
- find / -name "*.rpm" 2>/dev/null
View content of RPM package without extracts it
- rpm2cpio [RPM file path].rpm | cpio -tv
- Example: rpm2cpio.rpm | cpio -tv

Command That Already Installed

Locate the command's physical file path
- which [Command]
- Example: which mkdir
Query the RPM database using that file path
- rpm -qf [File path in Step 1]
- Example: rpm -qf /usr/bin/mkdir

Software That Already Installed

Check if the software package is installed by name
- rpm -q [Software Name]
- Example: rpm -q gnome-remote-desktop
View content of RPM package without extracts it
- rpm -ql [Software Name]
- Example: rpm -ql gnome-remote-desktop
Find the hidden setup scripts of the software
- You will see shell scripts starting with lines like postinstall scriptlet or preuninstall scriptlet. If it outputs nothing, it means the software was simple enough to not require setup scripts.
- rpm -q --scripts [Software Name]
- Example: rpm -q --scripts gnome-remote-desktop
