Simple Shell Alx C Project Collaborated by Chuku David Chimezie & Nehemiah Kagwari

Description

This project represents the realization of a shell, which was developed as a Milestone Project as part of the ALX Africa Software Engineering program. Named "The Gates of Shell," this project was undertaken during the first trimester to enhance students' comprehension of advanced shell programming concepts, encompassing processes, system calls, bit manipulation, file management, and error handling. Functioning as a straightforward UNIX command interpreter, this program emulates the core functionalities of the basic shell (sh). The entire implementation of this project was accomplished using the C programming language.

Description : This is a shell written in C. It is based on the Thompson shell.

Environment : Our shell was tested and built on Ubuntu 20.04.

Command Definition exit [n] Exit the shell, with an optional exit status, n. env Print the environment. setenv [var][value] Set an environment variable and value. If the variable exists, the value will be updated. alias[name[='value]] Reads aliases name unsetenv [var] Remove an environment variable. cd [dir] Change the directory. help [built-in] Read documentation for a built-in. The Installation Process : Getting HSH You would have to Clone the below repository and compile the files into an executable using the GCC compiler.

Then you Clone Learn how to clone . You then Create an executable by running the following command: gcc -Wall -Werror -Wextra -pedantic *.c -o hsh From there onward type in the following command and press your enter button. ./hsh Contributors : Chuku David Chimezie Nehemiah Kagwari
