Linux is one of the most successful operating systems on the planet. However, still, a lot of people are not well versed with it, which is why they continue to look for the best ways to use it. Bear in mind, even If you have studied everything about this operating system but never worked on it before, it will be challenging for you in the first few days.
In simple words, Linux is a beast because you can do much more with it than what your thought process would allow. For most developers, it is important to know a few basics, so they can initiate their tasks without any delay.
So if you have been looking for some valuable information on the basics of Linux, you’ve come to the right spot. Here, in this feature, we will walk you through a few basics of this operating system that you must not overlook:
1. Navigating the File System for the First time
How much experience do you have in development? Regardless of whatever your answer is, you will have to make yourself comfortable around the Linux file system.
As soon as you browse the terminal multiplexer, you will be navigated towards the main system. The next step will be to click on the Print working directory to check where you are. Secondly, you can easily move from your current location to anywhere else with the Change Directory. Many beginners don’t realize that they can also use the tab key to change the directory names.
2. File Permissions
Bear in mind, every file prepared in the Linux system has permission and ownership. The permission is for who is allowed and who can make changes to a file. So if you want to see the permissions on a file, you will have to use the command “filename” and something will be presented to you in the left column. It might be a little hard to read so let’s break it down for you.
If you are presented with a dash in the far left corner, it means that you have a file directory around. However, the next 3 dash groups will imply the permissions on the files. On the other hand, the owner who has created a file can easily be replaced.
Following reliable online publishers is a great way to understand file permissions and other technical tasks on Linux. You can follow publishers like Back to School Computers blog so you can find Linux information and also get to know about the latest gadgets.
3. Checking and Monitoring the Resource Usage on the System
It is not surprising to know that most of the system issues are caused by the shortage of resources on them. Especially when it comes to the memory, disk space, or the CPU, one might come across a plethora of issues.
Luckily, when you work on Linux, it has tools that will diagnose a prospective issue much earlier than any other option out there. As soon as you settle for the Top command, it will present you with a list of all the applications that have been running on the machine. This will also be inclusive of the memory consumption and CPU utilization.
This command is useful when it comes to identifying the processes that consume unnecessary resources. On the other hand, when you click on the “Free’ command, it will direct you to the current memory consumption on the machine.
So now that you have gone through some of the basics of Linux, it is imperative that you begin working with them. You might find it challenging in the initial stages but as you continue to complete your projects with its help, it will become much easier for you to successfully move towards the completion of the tasks.
A great way to boost your security using Linux is installing a proper security system in your home. You can use underground security cable and other gear to monitor your home easily with the Linux operating system.
