🧾 File Transfer Integrity Check (Updated for Merlin's Sound Bytes)

Check message delivery from Merlin 🧙‍♂️ via MP3s (ahem, “magical sound bytes”) — something may have disrupted the trusted courier line. Possibly... a Pirate Attack. 🏴‍☠️

Let’s update the 🧾 File Transfer Verification section to reflect the true importance of ensuring Merlin's messages have been properly delivered.

✅ 🧾 File Transfer Integrity Check (Updated for Merlin's Sound Bytes)

🧙‍♂️ "These MP3s are messages from the trusted magical advisor Merlin. They must be received in full — no empty scrolls (folders) shall pass."

🧭 Step 1: Identify Empty Folders (Trouble Spots)

find /castle/audio -type d -empty > /tmp/empty_folders.txt

This will tell you which message envelopes arrived empty at Camelot.
Review with:

cat /tmp/empty_folders.txt

Optional:

echo "Empty folders: $(wc -l < /tmp/empty_folders.txt)"

🪞 Step 2: Check the Source (Merlin's Tower)

On the source machine (Merlin’s Vault), check whether those folders actually contain MP3s:

rsync -av --dry-run --progress /mnt/merlin/messages/ frodo:/castle/audio/

Or compare with diff:

diff -qr /mnt/merlin/messages/ /castle/audio/

To confirm what’s missing.

🧰 Step 3: Resume the Message Transfer (with rsync)

Pirates may have disrupted the channel — but rsync’s magic is resumable:

rsync -av --progress /mnt/merlin/messages/ frodo:/castle/audio/

✅ It will only transfer what’s missing — folders, MP3s, everything.

🔍 Bonus: Check for MP3 Files Specifically

If you want to make sure actual sound bytes are present:

find /castle/audio -type f -name "*.mp3" | wc -l

And:

find /castle/audio -type d -exec bash -c 'shopt -s nullglob; files=("$1"/*.mp3); [[ ${#files[@]} -eq 0 ]] && echo "$1"' _ {} \;

→ This one shows folders that contain no MP3s at all, regardless of hidden files.

🛡️ Summary (for Camelot)

| Check                     | Command                              |
| ------------------------- | ------------------------------------ |
| Empty folders             | `find /castle/audio -type d -empty`  |
| Missing files via `rsync` | `rsync -av --dry-run`                |
| Resume transfer           | `rsync -av --progress`               |
| MP3 count                 | `find ... -name "*.mp3"`             |
| Folders with no mp3s      | see advanced `bash -c` example above |

Let me know when you want to automate this check — we can script a check_merlin_messages tool.

🎵 Merlin's voice must be heard. Let no Pirate silence the sound.
