One day this unexpected situation comes.
This is Linux.
This is your console.
We use Unix.
It wasn’t that bad:) Fortunately, I’ve received a good companion to get familiar with Unix and not to drown. Let’s get to the point.
What is Unix
For those, who use Windows on daily basis it might be surprising. Sure we are aware that there is something more out there (like Mac 🙂 ) but Unix? Linux, Unix, they are operation systems just like your beloved Windows 🙂
Traditionally, let’s start from Wikipedia’s definition:
Unix is a family of multitasking, multi user computer operating systems that derive from the original AT&T Unix, developed starting in the 1970s.
You may be familiar with Linux, Unix is a bit similar. They have common source and behave in a similar manner.
Linux is a pure Kernel – Unix consists of Kernel and some additional software. Linux is free – Unix – in most cases – is not 😦 What is more, Linux, originated from a programmer’s toy – became a powerful tool for large machines. Unix though, starting from exclusive , expensive environments, nowadays is used on small PCs.
What you have to know – there are different types of Unixes. They are comparable, but not exactly the same. To talk to Unix you need to get familiar with any shell.
Why do we need them anyway?
We need Unix in order to work on remote desktops – or – to enable multiple users to use one space. What is more – each Linux/Unix enthusiast would tell you that it’s reliable. They won’t prompt you seven times if you REALLY REALLY wanna delete this file, but at the same time, they won’t run an update in the middle of conversation 🙂
Unix is a common “tool” used by large companies. It is very useful in working with databases.
You have to make some effort to get familiar with console and simple script languages, but if I was manage to do so – you’ll be able to to that for sure:)
In my next posts I would go a bit deeper into subject and move on with simple commands, that are useful for me in testing activities and managing files.
Here you can find more complex information about what Unix is.
As always – I recommend you to install it by your own and just play around. You could also get familiar with Unix with this simple course from Codeschool here (no, the don’t pay me, they just have awesome courses) .
Stalk me on Twitter. Enjoy. 🙂
