Mini Grep C++

Overview

Mini Grep is a command-line tool written in C++ that allows you to search for specific text patterns within files. It is designed to provide basic text searching functionality similar to the Unix grep command.

Features

• Search for text patterns within files.
• Display matching lines.
• Perform case-sensitive or case-insensitive searches.
• Search for patterns using regular expressions (regex).
• Output results to the console or a file.

Usage

To use Mini Grep, follow these basic usage instructions:

1. Compile the program: You can compile the source code using a C++ compiler like g++ or cmake.

   mkdir build && cd build

   cmake ..

   make

2. Run the program with the desired options:

   ./minigrep [options] pattern file

   • [options]:

     • -i: Perform a case-insensitive search.
     • -r: Use regular expressions for pattern matching.
     • -o <output_file>: Specify an output file for results.

   • pattern: The text pattern you want to search for.

   • file: The name of the file or files you want to search within.

Examples

• Search for the word "bog" in a file:

  ./mini_grep bog ../poem.txt

• Perform a case-insensitive search for "pattern" in multiple files:

  ./mini_grep -i pattern file1.txt file2.txt

• Use regular expressions to search for email addresses and save the results to a file:

  ./mini_grep -r -o results.txt "^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}$" emails.txt
