All of the BSDs and some GNU/Linux distributions use Almquist for sh if not using a symlink to bash or dash. In fact, the first release of Slackware in 1993 had sh as a symlink to bash. I'm looking at the source code for the Bourne shell as included with UNIX SVR4 (circa 1988) and it's obvious that the version which Sun Microsystems/Oracle shipped with Solaris under the CDDL is a direct decedent. The license on the source code for the Bourne shell shipped with SVR4 clearly states: "THIS IS UNPUBLISHED PROPRIETARY SOURCE CODE OF AT&T" Brandon Vincent
