This is a simple UNIX command interpreter that can execute commands both interactively and from a file.

To use the Simple Shell project, simply clone the repository from GitHub by running the following command in your terminal:

git clone https://github.com/MHRasmy/simple_shell.git

Once you have cloned the repository, navigate to the project directory by running:

cd simple_shell/

Compile the program by running:

gcc -Wall -Werror -Wextra -pedantic -std=gnu89 *.c -o shell

To start the Simple Shell, run the following command in your terminal:

./shell

This will start the Simple Shell and you will see the prompt: #cisfun$ For example if you want to list the files and directories in the current directory use ls like this:

#cisfun$ ls

write any commands to execute it. This will list the files and directories in the current directory.

You can also execute commands from a file by running:

./shell [filename]

For example, if you have a file called commands that contains a list of commands, you can run:

./shell commands

This will execute each command in the file.

Note that this shell doesn't support pipeline redirection.
