LSH: A Simple Shell

This project is a simple command-line shell (LSH) written by LordSMH in C. It supports a few built-in commands and can execute external programs.

Features

• Built-in commands: cd, help, and exit.
• Ability to execute external programs.
• Uses system calls to create new processes (fork()) and execute programs (execvp()).

Usage

To compile and run the program, enter the following commands in the terminal:

gcc -o lsh main.c
./lsh

After running the program, you can enter your commands. For example:

> help
> cd ..
> ls -l
> exit

   • Example: cd /home/user

2. help: Display this help message.

   • Usage: help

3. exit: Exit the shell.

   • Usage: exit

Code Structure

• main.c: The main file that contains all the necessary functions to run the shell.
