Linux is a very popular job to go into, with the starting salary being quite competitive.
Even to have knowledge of it is a bonus within the industry therefore here are a few links to some sites which have the top most asked Linux Questions.
Here is a page from irishjobs.ie which holds multiple job opportunities, just in case you’re feeling lucky!
If you’d prefer to get it all into one video (you can use as an audio tutorial, just minimize the page holding the video) and fire ahead! For this tutorial you must have Linux setup and be within the virtual computer application. We start by opening the terminal, from there just follow the instructions! If videos are NOT for you, try my alternate option of slides.
If you, like many don’t want to have to pause the video every two seconds in order to see the code being used, use these simple powerpoint slides in order to obtain the same results.
Another useful command is mkdir
It can be used to create directories, folders etc. I will provide a basic demonstration on how the command functions.
Find out your learning style
The reason for completing this is simply to allow you to learn to the best ability you can. If you find it hard reading long sections of text, try watching a video or doing it yourself. This might help you to choose which sections to start at and how to go about them!
In the off chance you haven’t space or time to download Ubuntu. There are a few online terminals which also allow you to practice and learn within a Linux environment.
Choose one of the following to get started:
online terminal 2
Below is a short screencast using the following commands:
df – display filesystem, this shows information about the disk space usage. Alternately you can use df -h to display the same information but in MB/GB/KB.
du – directory usage, this displays the size of a directory and all of it’s subdirectories. Use du -h to display in MB/GB/KB.
free – this displays the amount of free space that’s available on the system. In my case it’s just of the virtual machine. Use free -m to display in MB.
uname -a – This provides a range of basic information about the system.
top – This displays the processes using the most system requirements at one time. Use q to quit.
If you’ve forgotten a command you used previously, just use the command ‘history‘ to view them.
To see what’s in the directory you’re currently in write the command ‘ls‘. As you can see I then used the change directory command ‘cd‘ to move into one of the folders.
If you aren’t sure or missed the post on directories check it out here: Directories
Using the command ‘pwd‘ you print the working directory. EG. where you are currently in the hierarchy.
A directory in software terms is what appears as the containers/folders and what they can hold. Within Linux, everything is treated as a file which contains a list of other file names etc. Directories being the key role in hierarchial file systems, is a good term to understand.
cd = Changes the directory
cd – = Takes you to the previous directory
cd .. = Takes you up a level
