Linux stands as one of the most popular choices for Operating Systems among developers. The field composed by multiple distros like Ubuntu, Linux Mint, Debian and others, is known among those who like to get their “hands dirty”.Linux-based operating systems often require users to type commands in the terminal for proper functionality. Modern Linux distributions, such as Ubuntu or PopOS, have App Stores, but you will still perform many tasks with some commands on the terminal. As result, if you’re wishing to dive into the world of Linux we’ve prepared this neat article with some of the 25 essential Linux Commands you need to know before proceeding with Linux.
The commands below include basic Unix commands such as ls, cat, cp, mv, grep, etc. We will also talk about some of the shortcuts that can help you take control of your operating system faster and in a more efficient way. Armed with this knowledge, you can swiftly adapt to Linux and harness the full power of the command line. Without further ado, let’s explore some of the most essential Linux commands.
Introducing the Linux Command and Explaining its Interface
The Linux command line is a robust tool that allows the user to perform various tasks. It’s one of the primary ways users can interact with Linux OS. It provides access to multiple tools that can help you get work done quickly and efficiently. With these commands it’s possible to understand Linux and all its capabilities.
For those unfamiliar, the Linux command line is basically a text-based user interface that administers the computer. Users can type in commands that the operating system will execute. The command line performs tasks similar to those of a conventional app with a graphical user interface (GUI). However, processes are executed without visual elements, making it less user-friendly. This is one reason why Linux is often associated with power users. The advantage is that you can execute advantage tasks just typing commands without needing to go through multiple windows of an app.
The Benefits of Using the Linux Command
There are multiple benefits in using the Linux Command (or Terminal) for executing tasks. We will list some of them below:
It’s faster because you don’t need to click or drag around apps or windows, you can complete tasks faster using the command line. This is quite useful if you want to quickly perform multiple commands.
Once you master the main commands and get familiar with it, it will be easier to remember and execute tasks.
The command line offers access to powerful tools to help you accomplish tasks quickly and efficiently. For example, if you need to search for a particular file or string of text, you can use the grep command, which is powerful and fast.
The command line is accessible from anywhere with an internet connection, which makes it convenient and fast to log in to a remote system.
