I guess to beginners, it just feels like a magic spell to get something installed!First I need to install Basilisk II, open a terminal window and bang in sudo apt-get intstall basilisk2 once that is done, I keep the terminal window open we will need it a bunch more next I need to deal with the hard disk first mounting my drive pops up as hard disk so I will be using that to refer to the macintosh drive under linux menus.Now you can run stack from the terminal. You can determine which version of the JDK is the default by entering java -version in a Terminal.I was just happy that I was able to type something in the Terminal and that it actually worked and did what I wanted it to do! I did not pay much attention to what I actually typed in. Install SWI-Prolog through the package manager: Open a terminal (Ctrl+Alt+T) and type: sudo apt-get install swi-prolog Quick start (Linux): Write a prolog program as a text file with a.pl ending.There can be multiple JDKs installed on the macOS system. Afterwards, update the package information: sudo apt-get update. Sudo add-apt-repository ppa:swi-prolog/stable.Homebrew installs packages to their own directory and then symbolic links their files into /user/local.Let us see what this command does, how it does that, and the reason you need to do this every time you need to install an app on your Linux computer.If you are running a Debian or Ubuntu based Linux distribution, there should be a package available to install the Powerline Fonts with the following. It is the package manager that most people feel comfortable with using it. Homebrew is the equivalent for the Mac. The command ‘ apt-get ‘ is intended for installing packages on Linux systems.Why do we need this command before we install software? and What do the 3 words in our command ( sudo, apt-get, and install) mean? Command Line Interface vs Graphical User Interface: What is the need to have these 2 interfaces? Once we confirm this list by typing the letter “Y” and press enter, apt-get will download and install everything for us.This prompt can be thought of as the factory manager asking you to confirm if you are okay with the list of things that need to be bought, and how much space they will these parts occupy once you install a conveyor system in your factory.If you still have an “incomplete feeling” about what this command means, read on for a longer and more informative answer where I explain the answers to the following questions So naturally, the first thing the manager will do is to have a look at the documents given by all the equipment manufacturers and information required regarding what are the parts available with each of them which are necessary to build the conveyor system.As you can see the first line in the screenshot above says “ Reading package lists… Done” which means that apt-get went ahead and read all the available software in the repos.The next thing the manager need to do is to go ahead and do the research of what are the parts needed for the conveyor and make a shopping list.As you can see, the second line in the screenshot says “ Building dependency tree” which means the apt-get is trying to see which other packages are required to make our desired package, gedit to run.You cannot install a belt for the conveyor, before installing the rollers and the conveyor motors, because a belt depends on the presence of a conveyor motor and a roller to do its job, hence roller, sensors and motors are dependencies for a conveyor belt! conveyor systemThen once apt-get knows what software to download and where to download them, apt-get tells us what additional packages will be downloaded and installed and how much extra space will be needed. FactoryIn the screenshot below I am trying to install an app named gedit, which is basically a text editor sudo apt-get install outputYour output might look a bit different than mine, but the important things to note here are the first 2 lines.Continuing with our “factory analogy”, if you “the factory owner” orders the manager to install a conveyor belt, the manager is smart enough to understand that you need an entire conveyor system, and you expect him to install everything for you.Let’s assume the manager has a list of files with given to him by all the equipment part manufacturers about what parts each of them produce.

This interface was made to make the operations on computers easier for regular users who might not be as tech-savy as programmers or software engineers. Graphical User InterfaceThe graphical user interface is the interface we are all familiar with, where we use our mouse or the touch screen to click through various icons and perform the desired action on our computers. Kali linux iso download not working for mac os xsince the CLI came first, this means GUI is still playing “catch-up” and this means you can do more things through the CLI than through the GUI The 3 main advantages of CLI are listed below Command Line InterfaceThere are several advantages of CLI compared to the GUI. This is because in data-centers are very power-hungry and better efficiency translates into lower power consumption and lower running costs, which means more profit for the company!Next let us see the basic structure of a command-line. We are getting there with natural language processing AI, but there is an awful lot of processing involved, which is very inefficient.Due to this inefficiency, voice input is never going to replace the good old command-line interface when it comes to cloud computing and data centers. Once you become a power user of Linux on the CLI, you can do a lot of fun projects which you never thought possible! This can include things like hosting your own website straight from your laptop, or tweak your old laptop to run as smoothly as a freshly bought one!Now that we have established the fact that the command line interface is very useful, let us learn a few basics of the CLI.Let us start by answering the question, ‘what is a command-line?’ What is a command-line?A command-line is a line of text which tells our computer to perform a specific action.As you might already know the words used in the text are specific for a given purpose and not some random text.For example, a computer will understand the command-line “ sudo apt install” and not “ please install software“!Unfortunately, our computers have not reached a state where we can just order the computer around the way we see robots are instructed in science fiction movies. Because of the resource efficiency, almost all of the webservers and cloud infrastructure are run via CLI without a GUI. Usually, sudo commands are followed by a password request, this is a security measure to prevent malware from getting automatically installed on our computers. This term is used to get administrative privileges so that we can install and remove software from our computer. We have not used any options in this command line.The term sudo stands for “ super-user do“. Sub-command, options, and arguments are optional parts though you will need them in most command-lines! What does the 3 words in our command ( sudo, apt-get and install) mean?Let us try to break the command line “ sudo apt-get install” into its building blocks and try to figure out the meaning of each word using the example “ sudo apt-get install gedit“ command break-upAs you can see in the above picture, the command-line “ sudo apt-get install” in question contains the command named “apt-get” ,the sub-command named “ install” and the argument named “ gedit“.
