Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Modifying the launcher to be run as root implies you'll always be running it as root. Running Wireshark as root is an unnecessary risk if you just want to capture packets for later analysis: use tcpdump or use tshark with sudo. When done chmod and chown the capture file so your unprivileged user can access it and launch Wireshark from that account. (Only if there's no other way and if you're that knowledgeable you know exactly what you're looking for should you capture and analyze traffic on the fly and as root. That being a one-off you should not modify the launcher but use Wireshark through gksu or kdesu.)
