Project Overview

This cli folder contains command-line utilities that offer functionality similar to common Unix tools but with custom implementations. Currently, it includes two projects: fc and cdiff.

fc

A command-line utility similar to wc, designed to count files by their extensions given a directory path. It lists the counts of all varying extensions in a neat tabular format.

Usage

Run the program with the directory path as an argument:

./build/fc.out <directory_path>

cdiff

A simplified, custom implementation of the 'diff' command-line tool. It supports three modes:

• Default Mode: Highlights differences between files line-by-line. This mode applies if no specific mode is provided as arguments.
• Context Mode: Displays lines around the differing sections, similar to 'diff -c'.
• Unified Mode: Shows differing lines with a few surrounding lines, similar to 'diff -u'.

Usage

Run the program by specifying the comparison mode and paths to two files:

./build/cdiff.out [-u | -c] <file1> <file2>

• Use '-u' for unified mode.
• Use '-c' for context mode.

Build Instructions

To build the project, use the provided Makefile. It will create both debug and release versions of the executables.

Targets

• build-debug: Compiles the source files into debug executables located in the build directory.
• build-release: Compiles the source files into release executables located in the build directory.
• clean: Removes the compiled executables from the build directory.

Commands

You can use the following commands in your terminal:

make build-debug     # For debug builds
make build-release   # For release builds
make clean           # To clean up build files
