Custom Terminal

Overview This is a custom-built terminal application created in C++ using fundamental operating system concepts like process management, I/O redirection, and history management. It supports common shell functionalities, including command execution, handling input/output redirection, maintaining a history of commands, and a basic implementation of job control using process forking.

Key Features Command Execution: Execute shell commands directly using exec. Command History: View the last 10 commands entered. Re-execute commands using !! (last command) or !n (nth previous command). Directory Navigation: Use the cd command to change directories, mimicking standard shell behavior. Input/Output Redirection: Supports input (<) and output (>) redirection for file handling. Process Control: Implements forking to handle multiple processes. Waits for child processes to complete unless executed with the & flag (background processes). Custom Tokenization: Tokenizes user input to handle special symbols like |, <, >, and &. Handles complex command structures gracefully. How to Run Clone the repository and navigate to the project directory: bash Copy code git clone cd custom-terminal Compile the program using a C++ compiler: bash Copy code g++ -o terminal terminal.cpp Run the terminal: bash Copy code ./terminal Usage Enter commands like in a regular shell. Use history to view the last 10 commands. Execute the last command with !! or any previous command using !n (replace n with the command's index in history). Redirect input/output with < and >: bash Copy code cat < input.txt > output.txt Use cd to change directories: bash Copy code cd /path/to/directory To run a command in the background, append &: bash Copy code long_running_command & Dependencies Linux/Unix-based operating system. GCC or another C++11-compatible compiler.
