Awesome Grep

Thank you for following me! https://cybdetective.com

Grep is a command line utility that searches files for lines that match a regular expression.

How regular expressions can be useful in OSINT. Theory and some practice using Google Sheets

The first version of this utility appeared almost 50 years ago, in 1973. But it is still actively used and maintained (the last version was released in August 2021! https://ftp.gnu.org/gnu/grep/).

This repository contains various modifications of grep, as well as analogues of this utility for a wide variety of search tasks.
