Linux hands estenosis lumbar on installation and the basics

This is where linux comes into the picture. For the average user, it sure looks like computing is dominated by windows or estenosis lumbar tratamiento macos or android and ios, but it’s safe to say that most “non-microsoft” products and services (and some of their own infrastructure) relies heavily and is built upon the industrial strength of estenosis lumbar tratamiento linux.

Since most of our currently used services rely so heavily estenosis lumbar tratamiento on linux, it only makes sense that you as a tech enthusiast estenosis lumbar tratamiento have a working knowledge of the OS and its key estenosis lumbar tratamiento components, reason being, should a need for troubleshooting arise, you rely on your muscle memory instead of trying to estenosis lumbar tratamiento figure it out and get frustrated at the time of estenosis lumbar tratamiento the issue (and trust me, there’s going to be a fair bit of frustration involved estenosis lumbar tratamiento at least in the first couple of days).

Now I’m pretty sure that if you’ve come to this article you have a fair bit estenosis lumbar tratamiento of understanding of what linux is and where it’s roots are, if not, however, you can read our posts introduction to linux operating system estenosis lumbar tratamiento and introduction to linux kernel, which should give you a brief idea of linux.

This series is going to be a completely hands on estenosis lumbar tratamiento one and you will be required to actually follow along estenosis lumbar tratamiento on your own machine, we’ve structured the post in such a manner that it estenosis lumbar tratamiento is extensively detailed while not becoming too overwhelming for beginners. Consider this series to be like the “linux for dummies” equivalent with the difference being that instead of throwing in estenosis lumbar tratamiento all of the knowledge at once, we will divide into smaller meaningful chunks. Unlike most of the posts we do, I would suggest you get ready for doing some work estenosis lumbar tratamiento (after all the best way to learn linux would be estenosis lumbar tratamiento to get your hands dirty with its nuances), but before we even begin all of that let me estenosis lumbar tratamiento give you a quick little primer on linux and clear estenosis lumbar tratamiento out some of the misconceptions about how linux is completely estenosis lumbar tratamiento different from unix. It won’t be too long I promise.

• linux: linux was built by linux torvalds and is heavily inspired estenosis lumbar tratamiento by MINIX (a unix-like distribution). It derives a lot of things from unix but is estenosis lumbar tratamiento a completely different system both inside and out. The original kernel was released in 1991 and after adding estenosis lumbar tratamiento things like drivers and a GUI and some much-needed polish, the full-fledged OS was released in 1992.

• unix: unix is not necessarily a fully open-sourced project. Parts of it are but in its ethos, it is a proprietary system. There are several versions of unix like BSD, macos etc. The primary development is done by AT&T and a couple of other commercial vendors.

• linux: unlike unix, linux thrives in an open-source ecosystem. The entire project is actively funded and monitored by the estenosis lumbar tratamiento linux foundation. The development is still supervised by linus who makes the estenosis lumbar tratamiento final call on a new addition. But essentially anyone with a programming background can download the estenosis lumbar tratamiento source code freely and make modifications.

Since we’re trying to target a broad audience with this post, and there’s no requirement for any prior experience with linux to estenosis lumbar tratamiento get started here, I’m going to make things as easy as possible so estenosis lumbar tratamiento that you can get onboard quickly. As we progress through the series, we will make the complexity of the post incrementally higher estenosis lumbar tratamiento so that you feel you get to learn something new estenosis lumbar tratamiento with each passing week. At the same time, the decision of making this a weekly series instead of estenosis lumbar tratamiento something released all at once was made so that you estenosis lumbar tratamiento get enough time to play around and try things out estenosis lumbar tratamiento on your without any supervision. After all the best way to learn something is to estenosis lumbar tratamiento break it yourself and build it back up.

For learning how to use linux, you must first get linux running on your system. There are a number of ways in which you can estenosis lumbar tratamiento do so, some of them would be using a live USB and estenosis lumbar tratamiento booting into it, installing it physically on your machine, creating a multi-boot system with 2 operating systems, installing it on a VM (virtual machine), and renting a linux server and sshing into it. I’m sure the experts would expand this list with a estenosis lumbar tratamiento bunch of more options but for the sake of brevity estenosis lumbar tratamiento let’s go with the above. While the end result of using all of the above estenosis lumbar tratamiento setups would be gaining access to a console to issue estenosis lumbar tratamiento linux commands, the steps to get there varies with each one in estenosis lumbar tratamiento number and difficulty.

As this is a pilot post, we’ll go with probably the easiest one out there which estenosis lumbar tratamiento won’t break your machine or current operating system in any estenosis lumbar tratamiento way and one which does not require experience with advanced estenosis lumbar tratamiento operations like partitioning a hard drive or configuring a remote estenosis lumbar tratamiento server. Agreed, they are cool, but I promise we’ll cover that once you’re familiar with the basics.

Once done, go ahead and launch virtualbox. Your screen should look almost similar to mine as shown estenosis lumbar tratamiento below minus the list of vms that I have (since I already have been using virtual box, I have a couple of vms set up, your list would be empty though).

Step 4: we will now go ahead and start installing ubuntu via estenosis lumbar tratamiento virtualbox. Click new on the top left of the virtualbox window. You would get a dialog box asking to name the estenosis lumbar tratamiento operating system. Type in ubuntu in the name, select type as linux and version as ubuntu (64-bit) and hit continue (newer versions of virtual box will automatically populate the type estenosis lumbar tratamiento and version field based on what you typed in the estenosis lumbar tratamiento name field).

Step 6: here you need to specify the hard disk that will estenosis lumbar tratamiento be used by the operating system. Often times, people upload pre-configured installations of their virtual box instances in the form estenosis lumbar tratamiento of something known as appliances. Appliances work in a plug and play manner.

So you can download the appliances, plug it into the virtual box instance and you’ll have a fully functioning operating system without any setup. (think of it like having 2 hard drives with 2 estenosis lumbar tratamiento operating systems and just switching them out minus the hassle estenosis lumbar tratamiento of unscrewing your PC up for this).

Step 8: now select the size. It’s advised to have a dynamically allocated drive because it estenosis lumbar tratamiento scales according to your needs compared to the fixed sized estenosis lumbar tratamiento option which will allocate the complete amount at once irrespective estenosis lumbar tratamiento of the fact that you would need it or not.

Now that we have done the set up let’s power up our machine. Select ubuntu from the list on the left and click estenosis lumbar tratamiento on start on the menu bar of the virtualbox window. Immediately a dialog will pop up asking you to insert estenosis lumbar tratamiento the image to boot ubuntu from. This is where the ubuntu image that we downloaded earlier estenosis lumbar tratamiento will be needed. Click on the folder button (shown in the image below) in the dialog and navigate and select the ubuntu image estenosis lumbar tratamiento and click open. Once that’s the image shown in the drop-down, click start.

Once the installation is complete, you will be asked to restart, go ahead and do that and once that is done, you will be greeted by a login screen for ubuntu. Just enter the password and there you go you have estenosis lumbar tratamiento successfully set up your ubuntu installation.

Alright, we are ready to start, just so you know, the proceeding screenshots will not look like the ubuntu terminal estenosis lumbar tratamiento because for increased visibility I will be using a linux estenosis lumbar tratamiento terminal on my server. Don’t worry about that, just focus on the commands and see if you get estenosis lumbar tratamiento the same results as I do in the screenshots.

Since this is the very first post in our hands-on series, we will limit ourselves to the very basics of linux estenosis lumbar tratamiento commands so that you are not overwhelmed, while still making sure that your interest doesn’t fall down and you quit. The commands we will cover in this post will be estenosis lumbar tratamiento divided into 5 different categories, they are as follows.

Once you hit the enter key, your terminal would display the hello world greeting. This not only kicks off our list of commands but estenosis lumbar tratamiento is also a good test of checking if everything is estenosis lumbar tratamiento working as expected. The echo command will simply display a line of text estenosis lumbar tratamiento that is specified after the commands. The quotation marks are optional but a convention is to estenosis lumbar tratamiento use it with quotes.

Let’s start off with a very basic command, that is to check the date and time via the estenosis lumbar tratamiento terminal. Aptly named date, the command displays the date and the current time in estenosis lumbar tratamiento 24-hour format along with your timezone. Type in the following in your terminal to check it estenosis lumbar tratamiento for yourself. Date

• pwd – before we start jumping around from one folder to another, let us learn how to find out which folder we estenosis lumbar tratamiento are currently in. You can do that using the pwd command. It stands for print working directory. Just type in the command as follows and check out estenosis lumbar tratamiento the result.

As you can see, this option along with ls has printed a bunch more estenosis lumbar tratamiento information on each file which includes file mode, number of links, owner name, group name, number of bytes in the file, abbreviated month, day-of-month file was last modified, hour file last modified, minute file last modified, and the pathname. I know most of it may not make sense right estenosis lumbar tratamiento now but don’t worry all you need to know right now is estenosis lumbar tratamiento that every command comes with a bunch of options you estenosis lumbar tratamiento can plug in, to fine tune the results returned.

• cd – now that we are familiar with how to list files estenosis lumbar tratamiento and check our current directory, let’s go over how to switch between directories. The command cd stands for change directory and is used estenosis lumbar tratamiento as follows. If you are inside a directory and have more directories estenosis lumbar tratamiento inside it, you can go into a sub-directory as follows.

Now that we are in the directory, how do we go out? Well you can again use an option along with cd estenosis lumbar tratamiento to step out of the subdirectory and into the parent estenosis lumbar tratamiento directory. In my example I am in ~/iosprojects/100daysofswift to go back to ~/iosprojects I will use the following command. Cd ..

• rmdir – the rmdir command stands for remove directory and it’s used to remove directories/delete directories. To delete a directory you need to be locate outside estenosis lumbar tratamiento it / located a level above it . Once you are out of the directory and that directory estenosis lumbar tratamiento is empty, just type the command as follows.

Next up let’s learn aout creating files. Since we are solely focusing on the terminal here and estenosis lumbar tratamiento no other applications, you may be wondering how would you go about creating estenosis lumbar tratamiento files of different format (txt, docx etc) right? Well this where our next command would come in picture.

Replace the FILENAME and EXTENSION with the ones you want. An example usage is shown below. If your terminal executes the command without a message most estenosis lumbar tratamiento likely the command was successful and you can check that estenosis lumbar tratamiento the file was created using the ls command.

NOTE: the rm command is irreversible so always make sure you estenosis lumbar tratamiento are deleting the right files. A safer way of doing it would be using the estenosis lumbar tratamiento rm command along with the -i option, doing so, the terminal will ask you to confirm if you want estenosis lumbar tratamiento to delete the file or not. It is used as follows. Rm -i FILENAME.EXTENSION

We created a file and we deleted it as well estenosis lumbar tratamiento but what about editing files? How to add and remove data? Well as excited you are about those aspects, trust me when I say it, it’s a little too complex and easy to get overwhelmed estenosis lumbar tratamiento if you are just starting out. We are doing the minimal ones here and as we estenosis lumbar tratamiento progress with every week, stuff like editing files from the terminal to the posts. Meanwhile, let’s move along. 5. Finding help

Alright! So we did a bunch of things on the terminal estenosis lumbar tratamiento right, but what if you forgot what are the options to estenosis lumbar tratamiento be used with a command or what a command does? Sure you can google it but there’s a better way where you don’t even have to leave the terminal.
