UNIX UTILITIES

INTRODUCTION

A few different UNIX utilities, simple versions of commonly used commands like cat, grep, zip, unzip.

OBJECTIVES

• Become familiar with a UNIX terminal/shell/command line.

• Learn how to use an appropriate code editor such as emacs.

• Learn a little about how UNIX utilities are implemented.

While the project focuses on writing simple C programs, you can see from above that even that requires a lot of other prior knowledge, including a basic idea of what a command interpreter (shell) is and how to use the command line in some UNIX-based systems programs (e.g., Linux or macOS), how to use an editor such as emacs, and of course a basic understanding of C programming.

OVERVIEW

• Several individual .c files for each of the utilities below: wcat.c, wgrep.c, wzip.c, and wunzip.c.

• Each should compile successfully when compiled with the -Wall and -Werror flags.

INSTALLATION GUIDE

• Clone this repository

• Ensure that you are working from the main branch, it is the most stable at any given time for this project.

• Open a terminal and navigate to the directory where the Makefile is located.

• Run the command make all to compile all programs. This will create four executable files: wcat, wgrep, wzip, and wunzip.

• To run the wcat program, run the command ./wcat [filename], where filename is the name of the file you want to read.

• To run the wgrep program, run the command ./wgrep [search_term] [filename], where search_term is the term you want to search for and filename is the name of the file you want to search.

• To run the wzip program, run the command ./wzip [filename], where filename is the name of the file you want to compress.

• To run the wunzip program, run the command ./wunzip [filename], where filename is the name of the file you want to decompress.

• To remove all executable files, run the command make clean.
