The Power of the Shell

A handful of text-processing commands let you slice, search, and transform data at speed. For a hacker this means filtering scan output, parsing logs, and finding secrets quickly.

This lesson covers grep, find, and awk, plus the glue between them.

grep searches text for lines matching a pattern. It is your first tool for finding interesting strings in files or output.

grep 'password' config.php
