A shell with a microscopic feature set
ush is a simple shell, implementing just the necessary, it currently provides
minimal line editing functions and keyboard shortcuts, simplistic file name
autocompletion, a fixed prompt, piping and a set of 8 builtins.
make
make install
You can either start ush from your current shell like so:
$ ush
or set it as your default login shell using
$ echo "/ush/local/bin/ush" | sudo tee -a /etc/shells
$ chsh -s /usr/local/bin/ush
ush is pretty minimalistic but still has a lot to offer if you are looking
for just the basics.

Missing redirection?
For input (<) try using cat and piping that into the command.
For output (>) try using tee and pipes.
For more complex command try building them in multiple steps, using intermediary files or creating a script file for it.
Missing a fancy colored prompt?
Prompts, like color schemes and theme, are not a thing in ush because the plethora
of choice and constant switching and tweaking can be a great waste of time. Try using
ush's prompt a little bit, you'll get used to it pretty fast.
Now, you might be missing information that used to be displayed for you in that prompt you had. Here are a few commands that can give you exactly that info only when you actually need it:
ush$ pwd
/Users/kiasaki/code/repos/ush
ush$ date
Sun 16 Oct 2016 11:46:26 EDT
ush$ whoami
kiasaki
ush$ hostname
kiasaki-mbp
ush$ git status -sb
