The grep command in Linux is a powerful text-search utility that allows users to find specific patterns within files or streams of text. It is an essential tool for system administrators, developers, and anyone working with text processing on Ubuntu and other Linux distributions.

šŸ“„ Installing grep

Most Ubuntu installations come with grep pre-installed. You can check its availability by running:

grep --version

If grep is not installed, you can install it using:

sudo apt update
    sudo apt install grep

šŸ“Œ Basic Syntax

grep [OPTIONS] PATTERN [FILE...]
  • PATTERN - The text or regular expression to search for.
  • FILE - The file(s) where the search is performed.
