This project is a custom implementation of a shell written in C. It aims to achieve all the features of a POSIX-compliant shell. It is part of the TILDE 3.0 mentorship program where 5 students worked on this project under the mentorship of 3 mentors.
We have implemented the basic structure of a shell and execution of some built-in and other external commands.
- Read Input: Read an input from the user.
- Tokenize: Tokenize the input with " " as a delimiter.
- Command Execution:
- Check whether the first token is a built-in or external command.
- Call the corresponding function and return the result.
- Loop: Go back to reading an input infinitely until
exitis called.
- Create functions for all built-in commands.
- Extensively debug all functions with all possible arguments and flags.
- Handle signals and arrow keys.
- Add tab completion.
