Advantages of using Terminal?

The terminal is the most used essential tool in Linux
An operating system, now lets took at its advantages to assert that claim :-

• Command Line Codes are standardized through POSIX and Single Unix Specification, so most of the codes you write in your own computer will work in all POSIX compliant machines.

• As Unix as built from Terminal and then up, almost everything is configurable from the Command-Line. Windows used to be just like this but they opted in favor of GUI and now some things can only be done through GUI.
• Because of the flexibility, this OS offers. the commands can be piped together, they can be captured and not even substituted in some cases.

• As humans are prone to error, even short scripts can be used to change settings in a  consistent manner. Even safety scripts can be built by the user rather than relying on which commands are safe to run in different circumstances.
• Unix utilities were designed to do a single task and they do it well, but if you combine them, they can become powerful expressions that can be used in our program. 

• It is simply faster than GUI since you just need to write codes and the system will implement them rather than accessing different files from different folders in GUI and then clicking to execute them.
• GUI doesn't cover all of the OS because it was never programmed for some things and only a person with expertise in Command-Line can, for example, perform the command mdf2so

• Lastly, by using command Line and Shell Scripts the user has the exact idea of what he is doing, rather than aimlessly wandering in the GUI system Command line may seem difficult to master, which it is, but it isn't difficult to use at all. You need to know the basics thoroughly and everything else is like learning any programming language.
