CLI Commands Repository

Welcome to the CLI Commands repository! This project was developed for educational purposes to learn the Rust programming language. The repository contains a collection of simple command-line utilities implemented in Rust, mimicking some of the functionalities of popular UNIX commands. These utilities include echo, cat, ls, and wc, each with various options for customization.

Overview

This repository contains a set of CLI utilities developed in Rust to simulate the behavior of commonly used UNIX commands. These utilities were created as part of a personal educational project to gain hands-on experience with Rust programming and command-line application development.

Commands

echo

The echo command outputs the given arguments to the terminal. It supports the following options:

• -e: Enables interpretation of escape sequences (e.g., \n for newline, \t for tab).
• -E: Disables interpretation of escape sequences (treats them as normal text).

cat

The cat command concatenates and displays the contents of one or more files. It supports the following options:

• -n: Number all output lines.
• -e: Display non-printable characters as escape sequences.
• -b: Number non-empty output lines.

ls

The ls command lists the files and directories in the specified directory. It supports the following options:

• -a: Include hidden files and directories in the listing.
• -l: Use a long listing format, displaying additional information such as permissions, owner, size, and modification date.

wc

The wc command counts the number of lines, words, characters, and bytes in a given file. It supports the following options:

• -l: Count only the lines.
• -w: Count only the words.
• -c: Count only the characters.
• -m: Count only the bytes.

Installation

To use these CLI utilities, follow these steps:

1. Make sure you have Rust installed on your system. If not, you can download it from Rust's official website.

2. Clone this repository to your local machine:

   git clone https://github.com/ambadidi/cli_commands.git

3. Navigate to the cloned directory:

   cd cli_commands

4. Build the utilities using Cargo (Rust's package manager and build tool):

   cargo build --release

Usage

After building the utilities, you can run them from the command line. Here are some examples:

# Run the echo command
./target/release/echo Hello, world!

# Run the cat command with options
./target/release/cat -n file.txt

# Run the ls command with options
./target/release/ls -a

# Run the wc command with options
./target/release/wc -l file.txt

Replace file.txt with the actual file path you want to use.
