How To Install lnav on Fedora 34

lnav is Curses-based tool for viewing and analyzing log files

Introduction

In this tutorial we learn how to install lnav on Fedora 34.

What is lnav

lnav is an enhanced log file viewer that takes advantage of any semantic information that can be gleaned from the files being viewed, such as timestamps and log levels. Using this extra semantic information, it can do things like interleaving messages from different files, generate histograms of messages over time, and providing hotkeys for navigating through the file. It is hoped that these features will allow the user to quickly and efficiently zero in on problems.
