This is a minimum viable product for a basic terminal shell. It is written in C++.
Compiled with C++17 using MSVC.
It is modeled after Bash.
- Builtin Commands. This basic shell supports the following builtins:
exit: Exit the shell with a specified status code. Ex:exit 1.pwd: Print the current working directory. Ex:pwd.cd: Change the current working directory. Ex:cd ../,cd ~,cd /d/Documents.
echo: Print text to the terminal. Ex:echo "Hello World". Supports typical Bash behavior for single and double quotes, as well as escape sequences. Interpolation not supported.type:- If the argument is a builtin, displays that to the screen.
- If the argument is not a builtin, displays the path to the program, if it exists.
- If the argument is not a builtin or a program, displays an error message.
- Other commands. If the command is not a builtin, it is assumed to be a program and is executed.
Compile (with at least C++17) and run the program. A shell will then be started. Type any of the above commands and any arguments you want.
