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!

A start to exploring the world of general systems admin.

Further exploration of the ps command and how to kill processes.

This episode covers the grep command and combines it with a pipe.

The episode also covers the ps command and combines it with grep and a pipe.

grep "day" hello.txt | more

grep -w "Hello" hello.txt | more

grep -w -n "Hello" hello.txt | more

ps -ef | grep 17142

In this episode, which will be a little over our ten minute length, we will consolidate what we have learnt to date and introduce the more command and about pipes.

Adding or appending to a file:- echo “Today is Sunday” >> ./TEST/hello.txt

more ./Test/hello.txt

cat ./Test/hello.txt | more

This episode covers how to see what is inside a file and how to copy files from one folder to another and how to move files from one folder to another

The podcast mentions the following commands that are typed in at a command prompt inside a terminal. They are here just for ease of reference.

mkdir foldername

echo "Hello World" > filename

cat filename

file filename

cp  filename newfilename

mv filename  ../folder  (moves the filename to a different folder from its parent)

In this episode we show how  to create new files and folders in Linux.

We show how to use the mkdir command to make a folder and the rmdir command to remove a folder.

We mention the -v option to these commands meaning "verbose" to provide more positive responses on the screen.

We explain the echo command and mention what standard output is and also how to display quotation marks.

Finally, we build on this echo command by showing how we divert the standard output into the creation of a file.
