Overview

The Simple Shell is a Unix-like shell implemented in C. It supports the execution of both built-in and external commands, manages command history, and allows for command pipelining using pipes (|). Features

• Command Execution: Execute external commands using execvp, as well as built-in commands like cd and history.
• History Management: Maintain a history of up to 100 commands, with options to view and clear history.
• Pipelining: Support for command pipelining, enabling the execution of commands in sequence with data passed between them.
• Robust Memory Management: Ensures proper allocation and deallocation of memory to prevent leaks.

Built-In Commands:

Change the current directory to < directory >.

cd <directory>

Display the list of commands entered during the session.

history

Clear the command history.

history -c

Exit the shell.

exit

Usage

To compile the Simple Shell, use the following command:

gcc -o sish sish.c -lpthread

To start the Simple Shell, simply run the compiled executable:

./sish

Entering Commands:

• Type commands as you would in a standard Unix shell.
• Use pipes (|) to chain commands together.
• Use the history command to view the command history.
• Use the exit command to quit the shell.
