Ubuntu started to flag which as deprecated and it seems which is not really standard and may vary across Distro. Drop the use of which and use the standard 'command -v' for this simple task. Which is still present in the prereq if some package/script still use which. A utility script called command_all.sh is implemented that will just mimic the output of which -a.
