Simple Shell

NAME

hsh - Holberton Simple Shell command interpreter (shell)

SYNOPSIS

./hsh

[command] [arguments ...]

DESCRIPTION

The hsh (Simple Shell) is an end of the trimester project for students at Holberton School of Software Engineering. The objective is to write a simple UNIX command interpreter that acts closely to sh

Overview

A shell is a command-line interpreter that provides a command line user

interf ace. The shell we built is a simplified iteration of a command

line similar to bash or dash. Simple Shell can be used in both interac‐

tive and non-interactive mode. In interactive mode the prompt will have

() around the $ sign ($). The first argument at argument [0] is under‐

stood by the shell to be a command. The shell will then run that com‐

mand if it can be found and arguments after t he first are treated as

modifiers or options.

To Compile

gcc -Wall -Werror -Wextra -pedantic *.c -o hsh

Example

Built-ins

1. cd - changes current directory of the process.

Syntax : cd [DIRECTORY]

2. exit - to exit from the shell you type exit and press ENTER.

3. env - prints the environment
