Basically, Linux is a kernel, not the OS.  The Linux kernel is monolithic. Monolithic kernels control the CPU, memory, Inter-Process Communication, device drivers, file system management, and system server calls.

Is Linux the kernel or OS?

 Linux is a kernel, not the OS:- The program in the system that allocates the machine’s resources to the other programs that you run is known as the kernel. The kernel is an essential part of an operating system, but useless by itself, it can only function in the context of a complete operating system.

About the awk command :

The awk command is a powerful text processing tool commonly used in Unix and Linux environments. It allows you to perform pattern scanning and text manipulation tasks on files, typically structured as rows and columns.

The basic syntax of the awk command is as follows:

awk 'pattern { action }' file_name

Here’s a explanation of the components:

pattern: This is a condition or regular expression that you want to match in each line of the input file. If the pattern is met, the associated action will be executed.

{ action }: This is the block of code that is executed when the pattern is matched. You can perform various operations on the matched lines here, such as printing specific columns, applying calculations, or modifying the content.

file_name: This is the file you want to process with the awk command.
