Shell Functions and Path Variables, Part 3
UNIX can present a bewildering array of tools and techniques, and it's almost impossible for any individual to be intimately familiar with all of them. In my experience, the best developers carry around a large bag of simple but useful techniques and are able to combine them rapidly into a working solution. You don't need to know every detail of every tool to do useful work, but you do need a bag of tricks you understand.
Please feel free to use any of the ideas I've described in this series. You can get a hold of the source code to the shell functions from www.netspinner.co.uk/Downloads/pathfunc.tgz. Let me know if you find any bugs, would like a new feature added, or make an improvement.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
