Homework 4
assigned 14 Nov, due 26 Nov (postponed to 3 Dec)

Write a shell in C (or, if you really want, Lex; I expect you to write homework 5 in lex anyway).

Minimum requirements

The shell should print a prompt, allow the user to type any ordinary Unix command, possibly with arguments, run that command until it finishes, print another prompt, run another command, and so on until the user types the special command "exit". You are not required to handle I/O redirection, pipes, semicolons, environment variable expansion (e.g. "$TERM"), file completion, wildcard filenames, or the "~" directory specifier.

Other things I'd like you to do in this version
