# fe-cli

`fe-cli` is a simple command-line application written in Rust that mimics the basic functionality of the `grep` command. It allows you to search for a specified pattern within a file and outputs the lines containing that pattern.

## Features

- Search for a pattern in a file
- Display lines containing the pattern

## Installation

To install `fe-cli`, you need to have Rust and Cargo installed. If you don't have Rust installed, you can install it from [here](https://www.rust-lang.org/tools/install).

Clone the repository and build the application using Cargo:

```bash
git clone https://github.com/vishalg0wda/fe-cli.git
cd fe-cli
cargo build --release
```

The executable will be available in the `target/release` directory.

## Usage

Run the `fe-cli` command followed by the pattern you want to search for and the file you want to search in:

```bash
./target/release/fe-cli <PATTERN> <FILE>
```

For example:

```bash
./target/release/fe-cli foo example.txt
```

This command will search for the pattern `foo` in the file `example.txt` and print each line that contains the pattern.

## Example

Consider the following content in `example.txt`:

```
foo bar
baz qux
foo baz
qux foo
```

Running the command:

```bash
./target/release/fe-cli foo example.txt
```

Will output:

```
foo bar
foo baz
qux foo
```
