A Custom Shell Implementation
Minishell is a custom shell implementation project written in C. It aims to provide a simple yet powerful shell interface for executing commands and managing processes. By working on Minishell, you will gain a deep understanding of process management, file descriptors, and command execution.
- Interactive Command Prompt: Minishell provides a user-friendly prompt where you can enter commands and interact with the shell.
- Command History: Easily navigate and repeat previously executed commands using the history feature.
- Command Execution: Minishell can search for and launch the appropriate executables based on the PATH variable or specified paths.
- Redirection: Redirect input from files or redirect output to files using the <, >, <<, and >> operators.
- Pipes: Create command pipelines by connecting the output of one command to the input of another using the pipe (|) operator.
- Environment Variable Expansion: Expand environment variables (e.g., $HOME, $PATH) to their corresponding values.
- Signal Handling: Handle signals like ctrl-C, ctrl-D, and ctrl-\ to provide expected behavior for an interactive shell.
- Built-in Commands: Minishell includes built-in commands like echo, cd, pwd, export, unset, env, and exit for essential functionality.
- Norm Compliance: The project adheres to coding standards and norms, ensuring clean and readable code.
- Memory Management: Minishell takes care of dynamically allocated memory to avoid leaks and ensure efficient resource utilization.
Working on the Minishell project offers valuable experience and showcases skills that employers seek in software developers:
- Process Management: Gain hands-on experience with creating child processes, managing their execution, and handling signals.
- System Calls and File Descriptors: Become familiar with system calls, file descriptors, and I/O operations, enhancing your low-level programming skills.
- Problem Solving: Solve complex problems related to parsing commands, handling input/output, and managing processes efficiently.
- Debugging and Testing: Develop proficiency in debugging techniques and writing effective test cases to ensure correctness and reliability.
- Attention to Detail: Strict adherence to coding standards, norms, and project requirements demonstrates your attention to detail and commitment to quality code.
- Collaboration and Version Control: Work on Minishell encourages collaboration using version control systems like Git, preparing you for real-world development environments.
