builtins

[Sukori]

our shell must implement the following builtins:

• [x] echo with option -n
• [x] cd with only a relative or absolute path
• [x] pwd with no options
• [x] export with no options
• [x] unset with no options
• [x] env with no options or arguments
• [x] exit with no options

@moop250 Request to make the builtins return their exit status instead of being void functions. Tell me if you want me to make this instead.

proposition:

int echo(char **in) // pipeline->params
{
    if (false)
        return (1); //or an appropriate errno
    return (0); //success
}
