The Heirloom Bourne Shell is a portable variant of the traditional Unix shell. It has been derived from OpenSolaris code and thus implements the SVR4/SVID3 level of the shell. The Bourne shell is suitable for * script portability testing * processing of legacy scripts * general script processing * interactive use Note that this SlackBuild installs the shell as /usr/bin/hsh rather than /usr/5bin/sh.
