Final episode in the Introduction to  Linux Commands.

Episode 1 introduced you to the Linux terminal, how to open it configure it and close it.  In fact, our first Linux command was exit and we then used uname largely to learn about options to commands and how we could use the man command to learn more about Linux commands.

Episode 2 was all about navigating around the Linux filesystem, introducing the pwd and ls commands.  Mention was also made of using the double-hyphen option of help when issuing commands and how that differed between the man command.

Episode 3 introduced you to environmental variables such as $HOME and $PWD.  The cd command was introduced and mention made of relevant and absolute paths to folders.

Episode 4 was all about making folders and files, using the mkdir, rmdir and the echo command.  You were introduced to the concept of standard output and how to redirect that.

Episode 5 introduced the cat, file, mv and cp commands so we could tell what type a file was and to display the contents and copy or move the file to elsewhere.  We explored the world of relevant and absolute paths a little more.

Episode 6 started to consolidate the learning to date and the introduction of the more command along with the concept of pipes.  Along the way we learnt how to append output to a file.

Episode 7 was all about grep – the search facility.  The ps command was introduced and combined with pipes and grep.

Episode 8 built upon the previous episode and now started into the world of systems admin using what we had learnt to date.  We learnt how to run commands in the background simply to learn about process IDs and how we could use the kill command to halt processes.

In episode 9 we built upon our systems knowledge by learning how to install and remove applications or as Linux prefers them to be known – packages.  The sudo and apt commands were introduced.

Episode 10 used sudo and apt again but this time to learn how to update and upgrade systems.

Episode 11 of course was the penultimate episode and simply covered other options to apt that had not been previously covered due to time pressures.

I also teased in episode 11 about the the next series of TechBull – Season 5 which should be available now.  Season 5 will cover tech news across the platforms but I fancy Windows 11 will take prominence!
