usage: collect-windows99-vmx-source-backup-search.sh [options]

Runs a public-key-only, no-content VMX source/backup filename search across
Linux hosts that may hold recovery artifacts for the missing Windows99 111 VMX.
It emits path fingerprints only. It never reads VMX file contents, writes files,
starts/stops VMs, restarts services, changes registry/task state, or reboots.

Options:
  --hosts LIST        Comma list like 110=wooo@192.168.0.110,120=wooo@192.168.0.120
  --roots LIST        Space-separated roots to search. Default: common backup roots
  --max-depth N       find maxdepth. Default: 7
  --timeout SECONDS   Per-host SSH timeout. Default: 35
  -h, --help          Show this help
