## **Introduction**
|
||||
I say you need to learn _Linux_ because really there is no reason not
|
||||
to. If you are pursuing a career in IT then you will without a doubt
|
||||
come across _Linux_ and having even basic knowledge of _Linux_ will get
|
||||
you far simply because it is everywhere. Many people struggle with the
|
||||
OS simply because it's fundamentally different compared to the other
|
||||
operating systems but give it a bit of time, you will master the
|
||||
basics and understand how much control over the system it gives you.
|
||||
You need to learn _Linux_ because there is no reason not to. If you
|
||||
are pursuing a career in IT then you will without a doubt come across
|
||||
_Linux_ and having even basic knowledge is very helpful. Many people
|
||||
struggle with the OS simply because it's fundamentally different
|
||||
compared to the other operating systems, but with a bit of time you
|
||||
can master the basics and unlock it's true power.
|
||||
|
||||
|
||||
|
||||
## **But Why**
|
||||
As mentioned before, there isn't reason not to. **Linux is everywhere**,
|
||||
from data centres to your phone. **Understanding how to use _Linux_ is
|
||||
great if you in or looking at a career in IT** because not many people
|
||||
-relatively speaking- know how to use it, it sets you apart from others.
|
||||
**I also believe _Linux_ gives you a deeper understanding of how your
|
||||
system works** at a lower level which can be great when it comes to
|
||||
troubleshooting. I think the most important factor is that **Linux is
|
||||
open source** and so you have the ability to look at the code you are
|
||||
running and with this comes full customisability of the system.
|
||||
**Linux is everywhere**, from data centres to your smart toaster. So
|
||||
if you are interesting in anything IT related then it's a great asset
|
||||
to have.
|
||||
|
||||
If you consider yourself a power user then _Linux_ is the perfect
|
||||
operating system due to the aforementioned customisability but also the
|
||||
command line. Many people are scared away from _Linux_ as they are
|
||||
intimidated by the fact that they have to use the terminal, however if
|
||||
you can overcome this "fear" then you have unlocked a great power and
|
||||
from my experience will start finding GUI's cumbersome.
|
||||
Linux is great for power users because it allows you to customise all
|
||||
aspects of your workflow to make it yours. The amount of
|
||||
customisability is mind blowing and an endless rabbit hole which is
|
||||
awesome as there is always something you could implement to improve
|
||||
your workflow.
|
||||
|
||||
Another great aspect of the customisability is the crazy number of
|
||||
options you can choose from to theme and tailor the Linux desktop
|
||||
experience to your liking. For some great and inspiring examples
|
||||
checkout [r/unixporn](https://www.reddit.com/r/unixporn/). This
|
||||
is what drove me to switch to Linux and Arch specifically.
|
||||
|
||||
Linux is very Light weight (Depending on Distribution) and much
|
||||
faster than competing operating systems simply because more often
|
||||
than not the distributions of Linux are not filled with bloatware.
|
||||
The most extreme examples of this are distros like Arch or something
|
||||
like LFS (Linux From Scratch) where you get a completely bare bones
|
||||
installation of Linux and are required to install everything from
|
||||
Network Managers, to the Desktop Environment, although this can seem
|
||||
pointless at the start as you use more and more distros you will find
|
||||
things you like and don't on each and something like Arch allows you
|
||||
to choose every bit of software that is installed and come up with
|
||||
something completely custom. Plus then you can say `I use Arch BTW`
|
||||
|
||||
## **How can you start**
|
||||
There are many ways you can start using _Linux_ and a lot of them don't
|
||||
require you to use _Linux_ as your main operating system. You do need
|
||||
to be committed to using Linux. Try not to fall back to Windows or
|
||||
MacOS if you cant figure something out, **search for solutions.**
|
||||
**Lastly try to get comfortable with the terminal.**
|
||||
|
||||
### **Install Linux as your main OS**
|
||||
This is the **Full Send** option. This is a great option if you know
|
||||
a move to Linux is something you want to commit to. I think this is the
|
||||
best option as you have to start learning Linux to get things done so
|
||||
you have incentive to keep going.
|
||||
This is the full send option.
|
||||
|
||||
|
||||
**Choosing a distro is fun but a huge time investment, you will hear the
|
||||
term `distro hopping` which is installing different distributions of
|
||||
_Linux_ and with the number of distros out there this can be daunting
|
||||
for new users. A great Distribution that I recommend is
|
||||
[Manjaro with KDE Plasma](https://manjaro.org/downloads/official/kde/)
|
||||
A great Distribution that I recommend is [Manjaro with KDE Plasma](https://manjaro.org/downloads/official/kde/)
|
||||
as it offers a heavily customisable desktop environment `KDE Plasma`
|
||||
and Manjaro itself is a great as it is based on Arch Linux so it can
|
||||
leverage the power of the AUR (Arch User Repository)
|
||||
and Manjaro itself is a great as it's Arch based but does not require
|
||||
you to start from step 0.
|
||||
|
||||
### ***MacOS*** **Terminal**
|
||||
_MacOS_ is actually _UNIX_ based and so **if you have an _apple Mac/MacBook_
|
||||
all you need is to open the Terminal** application and start playing
|
||||
around. I used this option for a while on my work machine and it works
|
||||
great. You get the best of both worlds with this option so if you have
|
||||
a MacOS device then this is a solid option. Not recommended if you
|
||||
don't have one of these devices simply due to cost 💸
|
||||
_MacOS_ is actually _UNIX_ based and so **if you have an _apple
|
||||
Mac/MacBook_ all you need is the Terminal** application. I used this on
|
||||
my work machine and it's a great alternative to the full send option.
|
||||
However I do not recommended this if you don't own one of these devices
|
||||
already due to cost 💸
|
||||
|
||||
### ***Windows WSL***
|
||||
The _Windows Subsystem for Linux_ is another great option to get started
|
||||
with _Linux_ as it installs the _Linux Kernel_ natively in windows and
|
||||
allows you to play around with a real _Linux_ environment, before doing
|
||||
a full send on my main machine this is the option I used.
|
||||
with _Linux_, it installs the _Linux Kernel_ in windows and allows you
|
||||
to play around in a real _Linux_ environment.
|
||||
|
||||
### **Virtual Machines**
|
||||
If there is a specific Distribution of _Linux_ you want to try without
|
||||
doing a Full Send then this is a great option however if you want to
|
||||
simply get to know the _Linux_ then choose the _MacOS_ terminal or _WSL_
|
||||
methods as they are a lot lighter.
|
||||
If there is a specific Distribution of _Linux_ you want to try then
|
||||
this is a great option. However if you want to simply get to know
|
||||
_Linux_ then choose the _MacOS_ terminal or _WSL_ methods as they are
|
||||
a lot lighter on system resources
|
||||
|
||||
## Conclusion
|
||||
**Why are you still reading go and get stuck in with _Linux_ 💨**
|
||||
|
||||
|
||||
|
||||
As with anything learning _Linux_ is a journey and will take time.
|
||||
Enjoy the experience of learning it and uncovering it's hidden powers
|
||||
because it is well worth it. I have linked some great resources for
|
||||
other great Linux related content that helped me.
