For the Bash Unix Shell we provide command completions support.
A generated version of the command completion for Bash is available at the here. To install download linked file and store it locally on your machine. To enable the completion you need to source the file.
source <path to prob_completion.sh>
To enable the completion automatically add the line above to your Bash settings, e.g. in the .bashrc or .profile files.
Bugs and improvements can be submitted on the project's GitHub Page
