Over the years, many different versions of Linux have become available for distribution, most of which are free for the user such as Ubuntu, Fedora and Mint, to name a few. Most of the programs that are available for PCs are also available for Macs running under OS X, but these two types of computers cannot use the exact same programs: for example, you cannot install the Mac version of the Microsoft Office suite on a Windows computer.
You can install other operating systems on Mac computers, but the OS X is only available for computers made by Apple. Android is an operating system designed for phones and other mobile devices. Android is not available for desktop computers, but in mobile devices it is extremely popular: more than a half of all mobile devices in the world run on Android. A user interface UI refers to the part of an operating system, program, or device that allows a user to enter and receive information.
A text-based user interface see the image to the left displays text, and its commands are usually typed on a command line using a keyboard. With a graphical user interface see the right-hand image , the functions are carried out by clicking or moving buttons, icons and menus by means of a pointing device. Larger image: text UI graphical UI. The images contain the same information: a directory listing of a computer.
You can often carry out the same tasks regardless of which kind of UI you are using. Modern graphical user interfaces have evolved from text-based UIs. Some operating systems can still be used with a text-based user interface.
In this case, the commands are entered as text e. Linux is an open source operating system whereas Windows OS is commercial.
Linux has access to source code and alters the code as per user need whereas Windows does not have access to the source code. The prior difference between Linux and Windows operating system is that Linux is totally free of cost whereas windows is marketable operating system and is costly. Linux is more flexible and free when compared to true Unix systems and that is why Linux has gained more popularity. While discussing the commands in Unix and Linux, they are not the same but are very much similar.
In fact, the commands in each distribution of the same family OS also varies. Solaris, HP, Intel, etc. CLI permits users to put in writing commands associate degree exceedingly in terminal or console window to interact with an operating system.
GUI permits users to use the graphics to interact with an operating system. A simpler solution: ip -details link show For virtual devices, device type is shown on the third line. Improve this answer.

For some reason, an interface "vboxnet0", which was added on my host by Virtualbox for Host-only networking does not show any type when I invoke ip -details link show.
I believe it should show up as a bridge connection. How to verify that? JdeHaan: Interesting. For me, your output writes null after "eth0" "ether" , after "lo" "loopback" and after "wlan0" "ether" , and after "tun0" it writes "none" , "tun".
So if I look for the second line to determine the type then tun -device will be "none" ; if I look for the third line then ethernet devices will be null. It's not elegant, but works: Using bash:! NOTE: On my machine, not all types are listed there, e. And the list of types may change over time. So do not ultimately rely on this list here!

Hum, this does not work on Ubuntu But it does on I'll check out limitations but it looks like we got at least a partial winner ;- — JdeHaan.
I executed it. Although ip link show shows me 9 devices, your script identifies only 4 of them. Loreno: Normal ethernet devices do not seem to have a type and so the scripts does not care about them.
I updated my answer accordingly. Also, the list of types seems to change over time; I updated the list of types in my script. Does maybe any of those two have affected you? See ip -details link show for the type of devices, if they have any. RIght now I have just 7 interfaces I have no idea where the other 2 have gone The script still identifies 4 devices.
