I don't know much about how these things work but I suppose you'll just need to write a couple clever bash functions that can process the usage blob from john to get a list of supported options and formats. I believe a simple example is /etc/bash_completion.d/make and a more advanced and powerful one is /etc/bash_completion.d/git Some things will be simple (like completing an option, --ru<TAB>) while others may be very tricky (like completing an option argument like --rules=know<TAB>). For the latter, you'll need to parse the right john.conf and possibly even follow .include lines in it... I'm not sure how you would *know* where to find john.conf in case john is compiled with JOHN_SYSTEMWIDE=1. This will probably be an interesting project! magnum
