- The Linux terminal is not almost difficult as you think.
- Understanding the basic things will help you start.
- These concepts apply to all Linux distribution.
When many people think of Linux, they think of strange and complex orders that are beyond the reach of new users. Those people may not know that modern Linux distribution does not require them to work with the command line.
But to reach the real power of Linux, the command line is something that people should understand at least, because after all, it may be required.

To start your journey with the Linux command line, it is important to know some things before diving. These aspects of the terminal are fundamental to obtain the most from the equipment.
Will we start our journey?
1. Terminal/Shell/Prompt/CLI – What is the difference?
The terminal is actually an app, such as the ganom terminal, the cassol of the KDE plasma, iterm2, and many others.
But what is shell? Simply put, Shell is a command-line interpreter that serves as a mediator between the user and the Linux kernel.

Prompt is the place where you type your command, and are usually displayed like this:
User name@hostname:
The CLI command stands for the line interface and is the most a bit of mystery as it is difficult to define. Usually, CLI is where you run the command. I like to think about it as the above three components (terminal, shell and prompt) work together.
2. History
Do you know that the shell maintains the history of the orders you run? Even better, you have access to that history. If you type History On the Prompt and Hit Enter, you will see the last 100 commands you have run. There is a quiet trick here. When you see your history, each command has an affiliated number. If you look at the command you want to run, you can remember it by typing it! The character immediately after the number of commands you want to run.

Linux Shell knows its orders and can help you. For example, you don’t remember the command you recently used, but you know it starts CaSType CaS And the hit enter, and you will be presented with all the commands that begin with the two letters. I have used it a lot in years because I can never miss the name of just one command.
4. $ Path
Linux $ is slightly complicated to explain the path, but goes here. If you have ever run a command in Windows, you know that you have to type a clear path for what you want to run. Suppose you want to run the command Jeddnet (Which is not actually a Windows command). You can’t just type Jeddnet And hit enter, because Windows will not know what to do.

On Linux, however, commands are usually global, so if you walk JeddnetAs long as the command is in a directory associated with your $ path, it will run. So, the Linux $ path includes directors that can be run globally. If you type $ PathThe output will include/UsR/BIN/,/USR/Local/BIN,/USR/Sbin, and similar directors will include directors. You can temporarily add a directory to your path with a command Export Path = “/Directory 1: $ path”. If you want to make that permanent, you edit ~/.Profile file.
5. What are for dots?
Suppose you have a shell script that you have made and you want to run it. It is said that you have made ~/scripts folder and all your scripts have been kept there. If you are in that directory, you can run a script .//script.shHe is a pioneer. Tells Shell that whatever you are doing is in the current working directory. On the other hand, two dots, look at the original directory. If we are talking about/home/jack/script, using a single dot/refers to home/jack/script, and refers to a double dot/home/jack.
6. Case sensitivity
The Linux terminal case is sensitive. In other words, if you have command ZDNET, you have to type it in all lowercases. If the command is ZDNET, you have to type it in uppercase. If the command is ZDNET, then you have to type it in the same way as it appears.
7. What happened to copy/paste?
Have you tried to paste something in the Linux terminal and with the True-Tru Ctrl+V keyboard shortcut? If yes, you came to know that it does not work. But why? I will escape the text of history here, but Ctrl+C is a keyboard shortcut to kill a command.
Because of that, Ctrl+C and Ctrl+V do not work as expected. Instead, use Ctrl+Shift+C and Ctrl+Shift+V.
you’ll get used to it.
