pro

#!/bin/bash -eu
# Need jq (should be quite rewritable without jq)
# Place it as something named `pro` in your path before `/usr/bin`
# e.g.`/usr/local/sbin/pro` or `~/.local/bin/pro` if that's in your path

if [ "${1:-} ${2:-}" = 'security-status --format=json' ]; then
    /usr/bin/pro security-status --format=json | jq -cM '.packages = []'
    exit 0
