guizo792 / mygrep

simple version of the classic command line search tool grep

Prerequisites

Before running MyGrep, make sure you have the following tools installed on your system:

1. Rust:

   • MyGrep is a Rust project, and you need the Rust programming language installed. You can install Rust by following the instructions on the official Rust website.

2. Cargo:

   • Cargo is the official package manager and build tool for Rust. It is usually included with the Rust installation.

Usage

To use MyGrep, follow these steps:

1. Clone the repository:

   git clone https://github.com/yourusername/mygrep.git

2. Navigate to the project directory:

   cd mygrep

3. Build the project:

   cargo build --release

4. Run MyGrep with the desired query and file path:

   ./target/release/mygrep query file_path

   You can also set the IGNORE_CASE environment variable to perform a case-insensitive search:

   IGNORE_CASE=1 ./target/release/mygrep query file_path

Example

Suppose you have a file named example.txt with the following content:

Rust:
safe, fast, productive.
Pick three.
Duct tape.

To search for the query "duct" in a case-sensitive manner, run the following command:

./target/release/mygrep duct example.txt

To perform a case-insensitive search, set the IGNORE_CASE environment variable:

IGNORE_CASE=1 ./target/release/mygrep duct example.txt

This will output:

Duct tape.
