A SMALL SHELL PROGRAM

Nutshell is a c program where we can execute commands.

initial structure of project

• Main Shell loop => main.c
• Command handling function => commands.c
• Header file for commands => commands.h
• Makefile for building the project

feautures to code...

• src/main.c: This file contains the main shell loop, which includes:

  • Reading user input.
  • Parsing commands.
  • Calling appropriate functions to execute commands.

• src/commands.c: This file defines the functions that handle specific commands such as:

  • ls for listing directory contents.
  • cd for changing directories.
  • Any additional custom commands your shell will support.

• include/commands.h: The header file that declares functions for command handling. This ensures modularity and makes the functions in commands.c accessible to main.c.

• Makefile: A file that provides build instructions, allowing you to compile the project with a simple make command. It defines how to compile each .c file and link them into the final executable, as well as a clean target to remove build files.

development status

• reading user input works
• parsing commands works
• connections working
• POSIX requirement doesn't work
• No directory changing creating works
• only outline of shell works
• *Next task will creating a directory
