Simple Shell

Description

The Simple Shell project is an implementation of a basic command-line interpreter. This shell replicates the behavior of the standard Unix shell, providing an interface for users to execute commands and manage processes.

Features

• Command execution: Executes commands with arguments.
• Built-in commands: Supports built-in commands like cd, exit, and env.
• Path handling: Searches for executable files in the directories listed in the PATH environment variable.
• Error handling: Displays appropriate error messages for invalid commands or arguments.
• Interactive and non-interactive modes: Operates in both interactive mode (user input) and non-interactive mode (script execution).

Getting Started

Prerequisites

• A Unix-like operating system (Linux, macOS)
• GCC compiler

Installation

1. Clone the repository:git clone https://github.com/petrushimself/simple_shell.git

2. Navigate to the project directory:cd simple_shell

3. Compile the source files:gcc -Wall -Werror -Wextra -pedantic *.c -o hsh

Usage

• Interactive mode:

  ./hsh

  Type commands and press Enter to execute.

• Non-interactive mode:

  echo "command" | ./hsh

  or

  ./hsh < script

Built-in Commands

• cd [directory]: Change the current directory.
• exit [status]: Exit the shell with a given status.
• env: Print the environment variables.

Example

$ ./hsh $ ls -l total 8 -rw-r--r-- 1 user user 0 Jul 31 09:47 file1 -rw-r--r-- 1 user user 0 Jul 31 09:47 file2 $ cd .. $ exit
