Awesome command-line example: finding duplicate files (Live!)

Yesterday I used the terminal/command-line command:

ls -R1 | grep '\.jpg' | grep -v "^thumbs.*" | sort | uniq -d

to find some duplicate files.

This (my first!) live-stream is going to break down this command and show you the power of knowing a few simple command-line tools.

Forgive me while I figure out some things in my new “studio”!

Command Line / Terminal Basics 5: Finding new commands

In this video we look at how we can use the “apropos” and “whatis” commands to find out about new commands, and we study “man” pages in a bit more detail

Command Line/Terminal Basics 4: Cats (More or Less)

This video shows you the basic tools for viewing files from the command line: “cat”, “more” and more’s successor “less” (so called because “less is more” – don’t say programmers don’t have a sense of humour!)

Command Line/Terminal Basics 3: Autocomplete and command history

In this terribly exciting video we speed up our command line use by learning about autocomplete and command history. Woo hoo! (Contains possibly genuinely exciting content!)

Command Line/Terminal Basics 2: Directories

In this video we’ll look at how to use folders, known as directories when on the command line. We’ll learn to navigate around the directory tree, create and remove directories, and recap on listing contents.

Command Line/Terminal basics 1: Getting started and finding how commands work with ‘man’

After a request from a friend, I’m going to try and do a series of videos on the command line/terminal for beginners. In this first video, we fire up the terminal, discover a bit about directories and commands, and learn how to find out what commands do and how they work using the “man” (manual page) command.

This is a tiny bit longer than the 5 minutes I aim for with Press Ups, but is still short. And apologies for the few audio issues. I’ll try to fix these for the next one.

Overview of Google Analytics privacy settings for GDPR

You may have had some emails from Google Analytics about new privacy tools. These are intended to help with GDPR compliance. So this video gives some background and shows two simple steps you can take with Google Analytics and WordPress to reduce the data you collect and retain using Google Analytics.


Web Browser Dev Tools Part 3: The Network tab and testing slow pages

In this video I introduce you to the Network tab in dev tools. You can use this to analyse slow-loading pages, locate images that might need to be optimised, see what scripts and styles are being loaded, and, if you’re more advanced, see and analyse the HTTP requests that are being made.

Web Browser Dev Tools Part 2: Inspecting pages

In the second part of my series on using dev tools, I look at how you can dive into your HTML, view it, see how it appears on screen and modify it. You can edit and add classes and hover states (and CSS, but that’s for a later video).

Web Browser Dev Tools Part 1: mobile website testing

Did you know that inside your browser is a magical toolbox called “Developer Tools”? Well there is, and it’s full of things that are useful to even non-web-developers.

I’m starting a little series on using developer tools, and starting by showing you how you can use “dev tools” to test your websites on different screen sizes and emulate mobile devices.
