Unix wc Tool

Overview

This project is a Unix/Lunix wc written in go from Coding Challenge. It processes text files to provide various statistics, including the number of bytes, lines, words, and characters.

Features

• Byte count (-c): Outputs the number of bytes in the file.
• Line count (-l): Outputs the number of lines in the file.
• Word count (-w): Outputs the number of words in the file.
• Character count (-m): Outputs the number of characters in the file.

Installation

1. Prerequisites: Ensure you have Go installed. If not, download and install it from the official Go website.
2. Clone the repository:

     git clone https://github.com/Jonath-z/unix-wc-tool

3. Navigate to the project directory:

   cd unix-wc-tool

Test

You can test with various flags to get the desired file statistics. Below are some examples:

Examples

1. Get the number of bytes in a file:

   go run main.go -c test.txt

2. Get the number of lines in a file:

   go run main.go -l test.txt

3. Get the number of words in a file:

   go run main.go -w test.txt

4. Get the number of characters in a file:

   go run main.go -m test.txt

Code Overview

The code is organized into several functions to handle different tasks:

• contains(s []string, str string) bool: Checks if a string is present in a slice of strings.
• getByteNumber(fileName string) int64: Returns the size of the file in bytes.
• getNumberOfLines(fileName string) int: Returns the number of lines in the file.
• countWords(fileName string) int: Returns the number of words in the file.
• counterCharacter(fileName string) int: Returns the number of characters in the file.
• ProcessFile(fileName string, cb func(string)): Processes the file by checking its existence and executing a callback function.
• main(): Parses command-line flags and invokes appropriate functions based on the flags provided.
