+sh probably needs to be trashed and restarted
+    When I started it, it was from a small online tutorial on the
+    basics of how shells work. It was more a demonstration of
+    things like forking and the execvp and waitpid functions. It
+    wasn't actually intended to grow into a proper shell. As it
+    stands this is just going to keep getting cobbled together
+    until it collapses under its own weight. It's probably better
+    to restart now, parse input using lex and yacc instead of
+    doing it ourselves, and work from there on implementation
+    of everything. We know the basics of how a shell does its
+    thing (fork, execvp, waitpid), now to use that with newer
+    knowledge of building language parsers with things like lex
+    and yacc, getting command line arguments with getopts, and
+    other things that will lead to a proper, fully-formed shell.
