WK2 Introduction to the shell Flashcards
Linux Shell
The shell is the command-line interpreter. That means it helps you communicate with the operating system through the command line.
Previously, we discussed a command-line interface. This is essentially the shell.
The shell provides the command-line interface for you to interact with the OS. To tell the OS what to do, you enter commands into this interface.
A command is an instruction telling the computer to do something. The shell communicates with the kernel to execute these commands.
Your OS doesn’t need the shell for most of its work, but it is an interface between you and what your system can offer. It allows you to perform math, run tests, and execute applications. More importantly, it allows you to combine these operations and connect applications to each other to perform complex and automated tasks.
