CDSH
CDSH is a simple implementation of a shell in C, and Since its purpose is demonstration (not feature completeness or even fitness for casual use), it has many limitations, including:
- Commands must be on a single line.
- Arguments must be separated by whitespace.
- No quoting arguments or escaping whitespace.
- No piping or redirection.
- Only builtins are:
cd,help,exit.
As of forking this open domain source, I wanted to give it more functionality. I do plan to give this the ability to be scripted and further as well has allowing some customization to the prompt, and per user file. I also plan to form processing of for, while, and if statements.
