Linux is an open-source operating system that has gained popularity in recent years. Many people are switching to Linux because it is more secure and efficient than other operating systems. If you are thinking of making the switch, or are just starting with Linux, here are the five most important aspects you should keep in mind.
- The command-line interface, or CLI
Whether you choose to join a college to learn Linux or decide to study on your own, you’ll need to understand the command-line interface or CLI. In this era, where you can buy college papers, some people might suggest that you buy a college term paper on the subject. But we’ll tell you why that’s not necessary. The CLI is where users type in commands to run programs or manipulate files. It might seem daunting at first, but it’ll become second nature with practice.
There are plenty of resources available online to help you understand the basics of the CLI.
- User Accounts
Another thing to be aware of is user accounts. By default, Linux systems have a root user account that has full control over the system. It’s generally considered bad practice to use the root account for daily tasks, so you’ll want to create a separate user account with more limited privileges.
You can do this by opening up a terminal and typing in the following command:
Where “username” is the user’s name you want to add. Once you’ve done that, you’ll need to give them a password. You can do this by typing in:
And then entering in the desired password when prompted.
Now that you have a user account set up, you’ll need to log out of the root account and log in to your new user account. You can do this by typing in the following command:
And then enter in your username and password when prompted.
- Package Management
Another thing to be aware of when learning Linux is package management. This is how you can install, update, and remove software on your system. APT (Advanced Package Tool) and YUM (Yellowdog Updater Modified) are the two most popular package managers. If you’re using a Debian-based distribution like Ubuntu, then you’ll use APT. If you’re using a Red Hat-based distribution like Fedora or CentOS, then you’ll use YUM. Each distribution also has its package manager, so check out which one your distribution uses.
Package management is an essential aspect of Linux because it makes it easy to keep your system up-to-date with the latest software releases. It’s also great for installing the software you may need for your work or hobbies. So, spend some time learning about package management on your Linux system.
- Understand File Permissions
Understanding file permissions is a great place to start if you’re looking for ways to improve your online privacy and security on Linux. By default, every file and folder on your system has an owner and a group associated with it. The owner can read, write, and execute the file (or folder), while members of the group can read and execute the file. Other users are considered “guests” and have no access to the file unless you explicitly permit them.
- The Kernel
Lastly, the kernel is the soul of your Linux machine. It manages everything from how processes are run to what resources are allocated and utilized. It’s essential to have a basic understanding of how it works to troubleshoot problems that may arise.
Linux is a great operating system for beginners. It is easy to install and use. The community is friendly and helpful. You can find help online or in person. With the right resources, you can learn Linux quickly and easily. The top five aspects to consider when learning Linux for a beginner are mentioned above.
