• This shell can handle:
  • space and tabs (multiples, errors, ...)
  • $PATH and environment
  • errors and return value
  • redirections (<, >, << and >>)
  • pipes (|)
  • builtins: cd, echo, exit, setenv, unsetenv
  • separators: ;, &&, ||

For instance, you should be able to execute the following command:

➜ ./t-sh

t-sh> cd ; </etc/hosts od -c | grep xx | wc >> /tmp/z -l ; cd - && echo "OK"

You can move throught you shell line with your arrow keys. ✨
