Kao što znate, trenutno je šesta sedmica moje NDG Linux edukacije za polaganje LCPI - 1 certifikata a ja sam veoma ozbiljno shvatio svoju obuku tako što sam kreirao nekoliko testova i sam u više navrata. Kako znate, progres svoje obuke s  testovima objavljujem na svojoj web stranici gdje možete pročitati izvještaje za svaku sedmicu koju sam do sada prešao, testove, laboratijske vježbe i slično.

Danas sam upravo imao prvu laboratorijsku vježbu u kojoj sam imao zadatak da kreiram na Desktop-u direktorij ndg_lab u koji sam trebao kreirati poddirektorij staff. Onda sam u taj isti direktorij trebao kreirati novu textualnu datoteku staff.txt te ju prekopirati i dati joj novo ime test.txt. Posljednji dio laboratorijske vježbe je od mene zahtjevao da u staff.txt datoteku upišem text 'Hello from Terminal!' te taj isti text prekopiram u test.txt datoteku. Ja želim da napomenem da rješenje ove laboratijske vježbe možete pročitati u mom .pdf dokumentu dole ispod gdje sam opisao cio postupak rješenja ovog zadatka uz video tutorijal koji je dostupan na mom YouTube kanalu.

Kako vidite pred vama se nalazi fino pripremljeno cijelokupno riješenje ove laboratorijske vježbe koju sam danas upravo imao. Treba da napomenem da 6 modul moje NDG Linux edukacije podrazumijeva detaljan rad sa fajlovima i direktorijima, kreiranje datoteka, direktorijuma preko Terminala, preimenovanje, kopiranje te premještanje jedne datoteke/direktorijuma na drugu lokaciju i slično. Izvještaj za 6 sedmicu mog kursa će biti objavljen nešto kasnije a sada vam preporučujem da pogledate i video tutorijal ove vježbe dole ispod.

Video 1: Tutorijal NDG Lab 1 vježbe je dostupan na mom YouTube kanalu.

To bilo sve u ovom izdanju NDG Lab vježbe. Uskoro slijedi i naredni NDG Lab 2 čija će objava i priprema malo potrajati ali u svakom slučaju nemojte zaboraviti komenrarisati ovaj moj lab, sam rad, obavezno stisnite SUB taster jer mi to mnogo pomaže u radu kako moje stranice pa tako i mog YouTube kanala. 

Do čitanja.

As many of you know, I'm on my second month, 6-th week of my NDG Linux Essential course which is preparation for taking LCPI -1 exam for Linux System Administrator. Couple weeks ago I have launched my very own YouTube channel /Amar Tufo/ where I published my videos from Ubuntu Linux tutorials and other areas of my interests. Therefore I have made couple days ago this amazing tutorial on 'How to convert .RPM package into DEBIAN using Alien?'. It's a very short video that explain what alien is and how to use it. I shall note that this tutorial is not intended for Linux beginners as to fact that it assumed that you have some experience in Linux, that you are well familiar with Linux terminology as well as using Terminal. Before you watch my video, let us explain shortly what is Alien, how can you find out about Alien via Linux and so on.

1. It's GNU/alien and not an Alien!

Don't you worry, there are no Aliens inside Linux. It's a tool designed to convert an .RPM package into fully flash .DEBIAN installation package that you can later install via Terminal or by GNOME software. But, if you are not certain about alien as a tool, there's one guy that you can ask and it's a man alien. Once you typed man alien in your Terminal, the following page will appear and it will look like this:

Without further delay, here's the official video of this short tutorial which I made proudly using Kdenlive open source video editor.

That's it. Make sure to watch this video and hopefully you will learn something from it. Please subscribe to my YouTube channel, like it, share it, and comment bellow the video. I see you next time.

Welcome to my NDG Linux Essential course week 5offcial report. It's been a while since I posted my four week report of my Linux education which is a preparation for taking LCPI - 1 (Linux System Administrator). As noted previously in my posts, NDG Linux Essential course is linked to my official category Linux Essential which is available at my website. It allows anyone to track my course progress as I went one. As you know, I have extended my education with my own Linux Lab's and Linux Exams to further my knowledge and to test my skills.

In the module 5 of my NDG Linux Essential course I have worked with getting help on Linux using the man command and it's argument. As you know, using man command you can find out in details arguments and option that goes with specific command such as man ls which will give you the following output.

Figure 1: Using man to find info about the certain command

I shall note that this is the one way you can get infos about each command you use in Linux Terminal. So if you're not sure about arguments that goes with command you use, than you know who you should contact, it's a man

There were also a PATH environment variables as well as which command that gives you exact path to specific command which will look like this. 

Figure 2: Using which command to find out the path of date

As you  probably know, the date command gives you current date, day and time and  such daemon is located in /bin/date folder.

One of the interesting part of this module was using the history command to print out previously used commands. History is very useful since it allows you to show a specific list of commands that have been previously used. It may be confusing but sometimes you have typed more than 100 commands and such list is to long to display but if you type $HISTSIZE = 25 it will print only 25 commands on your list. But, here's how history works in the following screen shoot.

Figure 3: Using history command in Terminal

You can also write a history shell variable named $HISTSIZE that will store exact number of your commands which looks like this.

Figure 4: Using history BASH shell variable $HISTSIZE

Entire module 5 was basically about providing help to the Linux user when using Terminal and so on. As far as my exam for module 5 which I have scored 10 and I'm really proud and happy on the fact that I'm getting better each time as I progress on my education. Here's my entire exam for module 5 that I have had.

Ok, this is my exam of module 5 for my NDG Linux education. Feel free to comment this article, take my exam to study it and use it as short Linux command reference. This is it for today and I see you soon in my module 6 of my Linux education. Till then best regards and have a nice weekend.

Before couple days ago I have create my CV or resume which will allow anyone to see my full activities, education, skills as well as other hobbies related to my work.

I shall note that this CV will be constantly updated as I progress and learn new skills on the way so that you can see my full experience so far and in the future.

Welcome to my NDG Linux Essential course week 4 official report. It's been a while since I posted my third week report of this course in which I'm enrolled and today was my first lab on module 4 of this course. If you wonder what was the lab about, well it was Command Line skills and some frequent commands used in BASH such as: which, echo $PATH, echo today is `date` a back quotes command as well as uname. Most interesting part of NDG Linux Essential course Module4 was certainly final exam for this part in which I scored the 8 grade.  Here's a quick screen shoot of my test as well as my grade.

Apart from writing about technology following the footsteps of Ubuntu Linux development and it's future, I'm an archaeologist and therefore you will find interesting archaeology articles at this site. I'm so much interested in deep past of planet Earh wondering what kind of world was it back half a billion years ago, what kind of animals walked it's surface and swim it's seas. Thanks to paleontology and combined forces of archaeologist as well, we can peace together an amazing story of our planet and it's amazing prehistoric times. In this installment I bringing top 5 prehistoric predators that once roomed the planet Earth. I shall note that this is a article on demand as response to Miloš Miladinović review of the movie 'Jurassic World 2015'.

You can also see my trailer for this article: 'Top five prehistoric predators that once roamed the Earth'.

1. Anomalocaris

Anomalocaris or abnormal shrimp is considered to be the Earth first super predator that swim the Cambrian seas some 541 million years ago. This predator with long body up to length of 2 m and unique pair of eyes for night hunting suggest that Anomalocaris was indeed top predator that mostly hunted smaller trilobites and other sea animals. Fossilized remains of this animal were found across the globe in Canadian Burgess Shale formation, Australia, China and across the United States before becoming extinct some 485 million years ago at the beginning of Ordovician era. 

2. Megalograptus

On the prehistoric Earth, life was flourishing in the seas for as much as 350 million years. Among the seas predators comes Megalograptus a fierce scorpion predators from eurypterid family that lived during Ordovician era around 445 million years ago. Having been as on the first creatures to step on to dry land, Megalograptus was probably a night hunter preying upon smaller orthocones, trilobites and early fishes. It's fossilized remains were mostly find trough United States before being extinct in Ordovician mass extinction event around 455 million years ago.

3. Brontoscorpio

Meet Brontoscorpio, monstrous sea scorpion of the Silurian period some 440 - 417 million years ago. This monster scorpion sweam the Silurian seas alongside Cameroceras, Cephalaspis and Pterygotus. It has an armed body just like Anomalocaris and stinger with size of a light bulb. It can grew up to one meter in length and probably feed on trilobites and Cephalaspis which was armored fish as well. Fossilized remains of Brontoscorpio were mostly uncovered in Trimpley and Worcestershire, England UK.

4. Dunkleosteus

Dunkleosteus was a large armored fish that lived during the late Devonian period some 380 - 360 million years ago. It was named in 1958 after David Dunkle, a curator at Cleveland Museum of Natural History. Dunkleosteus was a top predator during much of Devonian period, a period known as age of fish. It was able to grew as much as 10 meter in length, had fierce bite about 8000 pounds. This predator feed on other fishes as well as other smaller Dunkleosteus which was according to some researchers a sign of  cannibalism due to probably food shortage. Fossilized remains of this predator were found across North America, western Europe, northern Africa, Texas, California, Pennsylvania and Ohio. It is assumed that Donkleosteus was eventually extinct at the dawn of Carboniferous period, fourth period of Paleozoic era, around 358 million years ago.

5. Mosasaurus

 Image credit: 

Mosasaurus was a large marine reptile that lived during the Cretaceous period some 90 million years ago. Able to grew as much as 18 meter in length, this giant prehistoric monster feed on sharks, plesiosaurus, giant turtles, birds, as well as other mosasaurus. Named after Muse river in Netherlands were the first mosasaurus fossil were first discovered in 1764, and later across the globe in northern Europe, eastern Europe, Russia, Turkey, the Middle East, Canada, South America. Mosasaurus was a dominant sea predator for 40 million years ago before being extinct at the end of Cretaceous period 65 million years ago alongside the dinosaurs.  


Although today we knew much about prehistoric life and lifeforms on planet Earth, jet there are still dozens of species waiting to be discovered. As much as we think that Anomalocaris and Mosasaurus look the way we think they dis, on thing has to be always in our mind, it's just a speculation based on our model of reconstruction which we used to bring those beasts back from dead. Further paleontological research and archaeological digs across the globe will help us to understand the way these beasts feed, way they adopt to Earth climate changes and food supply that sustain they're enormous length is an amazing story of evolution of life on planet Earth. But thanks to fossilized records in Earth geological layers, that we can today told an amazing story of prehistoric life on Earth.

Welcome to my third week report on my NDG Linux Essential course. As I have promised early on my few posts, I have made a very good progress in my Linux adventure so far. I have completed four modules in my NDG Linux Essential course and also to further my knowledge made a couple Linux test my self covering Linux terminology, Networking, BASH scripting skills, Linux directory architecture and much more. As you shall see in a moment, these are practically qualified LCPI - 1 tests which do not differ from official tests compiled by Linux Institute.

 Test above consists from 30 questions covering basic Linux terminology, desktop environments, questions that required answers on the line such as: ' Which directory contains programs which are compiled and installed manually?' and so on. I'm really happy about these tests aside from official exams that I take at my NDG Linux Essential course, which requires exam completion in order to complete each module. As for my test, you may download it, study it and take it you're self and check your knowledge in Linux.

That's it for today.
We see you soon at 4-th week report.
