This repository contains my implementation of a shell as part of the CodeCrafters.io Shell Challenge. Built entirely in Rust, this shell replicates basic Unix shell functionalities.
cd: Change the current working directory.pwd: Display the current working directory.echo: Print arguments to the standard output.type: Display whether a command is a built-in or an external executable.exit: Terminate the shell.
- Seamlessly runs external binaries available in the system PATH.
- Displays standard output and standard error from commands.
- Handles relative paths, absolute paths, and home directory shortcuts (
~). - Ensures proper context management for path changes and directory traversal.
- Maintains state for executables and the current working directory.
- Dynamically updates the list of available executables from the system PATH.
- Supports handling single and double-quoted strings.
- Escapes special characters in commands where appropriate.
- Add support for I/O redirection (e.g.,
>,<,>>). - Implement piping (e.g.,
command1 | command2). - Add tab-completion for commands and file paths.
- Support environment variable management (e.g.,
export,unset).
- Add a history feature to navigate previous commands.
- Add unit and integration tests for core functionalities.
- Optimize performance for large or complex commands.
