Differences in /bin/sh executable across Linux and MacOS

[00Nave198]

Currently, the hyperqube.sh shell script uses /bin/sh as its primary interpreter. On Debian/Ubuntu Linux systems, this executable is linked to the dash shell, which does not run the script in the intended manner. See the error below for more info.

============ Unrolling with genQBF + Solving with QuAbS ============
generating QBF BMC...
exec/genqbf: wrong argument '-f'; option '-F' expects one of: AA AE EE EA EAA.
Parses a Boolean formula and generates a representation of the input formula
and generates output of the formula in some formats: Boolean (default) QCIR, QDIMACS, AIGER.
It can optionally transform the formula to cnf,dnf,nnf and perform simple simplifications.
  -i input file
  -a do not append "_A" and "_B" for systems A and B
  -I input file for initial state for A
  -R input file for transition relation for A
  -J input file for initial state for B
  -S input file for transition relation for B
  -P property file
  -F {AA|AE|EE|EA|EAA}format of the unrolling: AE, AA, EE, EA, or EAA

This error can be easily avoided by prefixing the hyperqube.sh script with bash as in bash ./hyperqube.sh ....

A proper solution for this issue would be to change the default shell in the hyperqube.sh script to /bin/bash, which would guarantee a more unified experience across different platforms.
