Is a simple Unix/Linux shell implementation that allows users to execute commands and interact with the system. This shell is developed in C and provides a basic command-line interface for users to input commands and receive responses from the program.

The following simple-shell functions can be performed:

• Interactive and no-interactive Command Execution: Users can enter commands in the shell and receive responses from the program.
• Input of commands in the form of absolute path, interpretation and execution
• Input of commands in the form of absolute path, interpretation and execution
• Interactive and non-interactive operation for command entered without absolute path
• Interpretation and execution of exit command
• Exit program with (ctrl + d)
• Environment Variable Printing: The shell can display the system's environment variables using the "env" command.

To compile and run the Custom Shell on your system, follow these steps:

Clone the repository:

git clone https://github.com/FoulTrip/holbertonschool-simple_shell.git

Compile the source code using GCC:

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

Run the shell:

./hsh

pass the commands in the stdin but no prints the prompt

$ echo "/bin/ls" | ./hsh

The program is execute and the prompt is print, and wait for the user.

• $ ./hsh
• #cisfun$

Once the shell is running, you can interact with it using the command-line interface. Here are some commands you can try: Entering commands: Type in various commands and press Enter to execute them. Exiting the shell: Use the "exit" command to exit the shell. Displaying environment variables: Use the "env" command to print the system environment variables

The Custom Shell is divided into several modules:

• main.c: This file contains the main function responsible for creating an interactive loop in which users can enter commands and receive responses from the program.
• main.h: Header file containing function declarations and necessary includes.
• executeCommand.c: This file defines the executeCommand function, responsible for executing user commands using the execve system call.
• path.c: This file defines the findExecutable function, which helps locate the full path of executable commands.
• printEnv.c: This file defines the printEnvironment function, which prints the system environment variables.

This project was made possible thanks to the collaborative efforts of David Vasquez: Developed the initial shell functionality and main loop and Ricardo Valdes: Implemented the command execution and environment printing functions.
