dash is the Debian Almquist shell: a small, fast, and POSIX compliant shell. It is well-suited for startup scripts, and is used on Debian (and derivative distributions) as /bin/sh.
As some shell scripts may have "bashisms" in them, dash is not guaranteed to work as a /bin/sh replacement on Gentoo, out-of-the-box.
See the terminal emulator article for some general usage pointers, though dash is not often used in interactive mode.

The output of a shell can, in some conditions, become corrupt. See the terminal emulator article for instructions to help fix this.
