explain the awk command in bash script

The `awk` command is a powerful tool in Bash scripting that allows you to manipulate and analyze text data in a file or a stream. It is a programming language that specializes in processing structured text data.

Here is a basic syntax of the `awk` command:

awk [options] 'pattern {action}' file

- `options`: These are optional parameters that modify the behavior of the `awk` command.

- `pattern`: This is a regular expression that matches the desired text data in the input file.

- `{action}`: This is a set of commands that are executed on the text data that matches the pattern.

- `file`: This is the name of the input file that contains the text data to be processed. If omitted, `awk` reads from standard input.

Here are some common examples of using `awk` in Bash scripting:

- To print the first column of a CSV file:

awk -F',' '{print $1}' file.csv

- To calculate the sum of the second column of a space-delimited file:

awk '{sum += $2} END {print sum}' file.txt

- To print lines containing a specific keyword:

awk '/keyword/ {print}' file.txt

- To print lines with more than 3 fields:

awk 'NF>3 {print}' file.txt

These are just a few examples of what you can do with `awk` in Bash scripting. Its flexibility and power make it an essential tool for any data processing task.
