Linux command(awk)

Simply put

Awk is a versatile scripting language used for text processing and data manipulation. It was originally designed for Unix-based systems but is now widely available on various platforms.

Awk operates on a line-by-line basis, reading input files and processing each line according to the instructions specified in the script. It is commonly used for tasks such as filtering, searching, and transforming data.

Awk scripts consist of one or more patterns and associated actions. A pattern specifies a condition that must be met for the action to be executed. Actions are commands that define what should be done when the pattern is matched.

For example, the following awk script prints all lines containing the word “hello”:

awk '/hello/ {print}' myfile.txt

In this script, the pattern is /hello/ , which matches any line containing the word “hello”. The action is {print} , which tells awk to print the entire line. The input file is myfile.txt .
