When should you use awk command?

The awk command is a powerful text processing tool used in Unix/Linux systems for pattern scanning and processing. You should use awk when you need to:

  • Extract data from structured text files such as CSV or TSV.
  • Perform calculations or summarize data.
  • Transform text files into reports or other formats.
  • Filter and manipulate data based on patterns or conditions.

Here’s an example of using the awk command to print the second column from a CSV file:

awk -F, '{print $2}' file.csv
