I bungled the commands and wrote sh -man
Now I've entered a program called sh-3.2 that is seemingly impossible to exit.
Ctrlc,Ctrlz, or Ctrlxdoes not work.
exit, quit, q, :q also does not work.
All google answers are for exiting shell scripts programmatically.

Ctrl+Ddoes the trick for me. – jippie Nov 26 '12 at 7:50
