I thought about having a shell that is lisp based for Linux, as a way of forcing myself to use lisp more often, since I'm on and off with it. Though running things like apt-get and such would be interesting (sudo (apt-get (install racket chromium-browser))) or so
It would be great to have Scsh as an installable package for the major Linux distributions? For example, on Ubuntu 14.04 LTS it exists but is not installable, says something about "unresolvable dependencies". Don't know about other distributions.
Then, there was an effort to port Scsh to the GNU Scheme, but the work was lost or abandoned somehow if I understood it correctly.
For people spending a lot of time on with Unix shell(s), a great Lisp/Scheme shell might have been the entering point. But somehow the great work that has been done at the beginning cannot be brought to masses.
