This project aims to build a basic command-line shell. The shell processes user input, executes commands, handles file redirection, and manages pipes. Minishell is a great tool for understanding how a shell works by implementing core shell functionalities.
The goal of the Minishell project is to create a simple UNIX-like shell. It involves handling user input, parsing and executing commands, implementing file redirection and pipe operations. This project provides in-depth knowledge on system calls, memory management, and string manipulation in the C programming language.
Minishell operates similarly to a standard shell and supports various functionalities. Here are some usage examples:
- Command Execution: Type simple commands and press Enter.
- Example:
ls -l
- Example:
- File Redirection: Use '>' or '>>' to redirect output to a file, and '<' to read input from a file.
- Example:
echo "Hello World" > output.txt
- Example:
- Pipe Operations: Use '|' to pass the output of one command as input to another.
- Example:
ls -l | grep minishell
- Example:
- Check Command Result:
$?returns the exit status of the last executed command.- Example:
ls -l; echo $?(Checks if the last command succeeded.)
- Example:
- Background Processes: Use '&' to run a command in the background.
- Example:
./script.sh &
- Example:
To build and run the Minishell project, the following requirements must be met:
- A Unix-based operating system (Linux, macOS) or a terminal emulator.
- GCC compiler: The project should be compiled with the GNU C Compiler.
- Bash or a similar shell: For testing and executing commands.
- C libraries: Access to standard C libraries and system calls is required.
- Make utility: A Makefile is used to build and manage the project.
In addition to the main shell functionality, the project includes various helper functions and structures. Key components include:
- Makefile: Used to compile and build the project.
- minishell.h: Header file containing structure definitions and function prototypes.
- minishell.c: Contains the core shell logic.
- executor.c: Handles command execution and redirection operations.
- parser.c: Parses user input and processes commands.
- signals.c: Manages signal handling and control logic.
- utils.c: Includes helper functions for string manipulation and memory management.
