dash 0.5.5.1-2ubuntu2 (i386 binary) in ubuntu karmic

 The Debian Almquist Shell (dash) is a lightweight POSIX-compliant shell
 derived from ash.
 .
 It can be usefully installed as /bin/sh (because it executes scripts
 faster than bash), or as the default shell for the superuser. It
 depends on fewer libraries than bash, and is therefore less likely to
 be affected by an upgrade problem or a disk failure. It is also
 useful for checking the POSIX compliance of scripts.
