Script to pause seeding torrents before invoking mover

My unraid mover almost never moves the big linux ISOs my torrenting docker downloaded to the cache because it can’t move files that are being seeded as they are active.

This scripts pauses all seeding torrents, runs the mover, then resumes the torrents.

I set it up to run every day at 2h30 AM using “user scripts”

#!/bin/bash

# Script to pause 100% completed torrents, run mover, then resume
# Place in User Scripts plugin

DELUGE_CONTAINER="binhex-delugevpn"
DELUGE_USER="admin"
DELUGE_PASS="deluge"

# Helper function to add timestamps
log() {
    echo "[$(date '+%Y-%m-%d %H:%M:%S')] $1"
}

log "Starting mover script"

# Get list of 100% completed torrent hashes
log "Finding completed torrents..."
COMPLETED_TORRENTS=$(docker exec $DELUGE_CONTAINER deluge-console "connect 127.0.0.1:58846 $DELUGE_USER $DELUGE_PASS; info" | \
    grep "^\[S\]   100%" | \
    awk '{print $NF}')

if [ -z "$COMPLETED_TORRENTS" ]; then
    log "No completed torrents found to pause"
else
    TORRENT_COUNT=$(echo "$COMPLETED_TORRENTS" | wc -l)
    log "Found $TORRENT_COUNT completed torrents to pause"
    
    # Build a single command string with all pause commands
    PAUSE_COMMANDS="connect 127.0.0.1:58846 $DELUGE_USER $DELUGE_PASS"
    for hash in $COMPLETED_TORRENTS; do
        PAUSE_COMMANDS="$PAUSE_COMMANDS; pause $hash"
    done
    
    # Execute all pauses in a single connection
    log "Pausing all torrents..."
    docker exec $DELUGE_CONTAINER deluge-console "$PAUSE_COMMANDS" > /dev/null 2>&1
    log "All $TORRENT_COUNT torrents paused"
fi

# Wait for file handles to release
log "Waiting 10 seconds for file handles to release..."
sleep 10

# Run the mover
log "Running mover..."
mover start

# Wait for mover to actually finish
log "Waiting for mover to complete..."
while pgrep -x "mover" > /dev/null; do
    sleep 60  # Check every minute
done
log "Mover finished!"

# Resume all previously paused torrents
if [ ! -z "$COMPLETED_TORRENTS" ]; then
    log "Resuming torrents..."
    
    # Build a single command string with all resume commands
    RESUME_COMMANDS="connect 127.0.0.1:58846 $DELUGE_USER $DELUGE_PASS"
    for hash in $COMPLETED_TORRENTS; do
        RESUME_COMMANDS="$RESUME_COMMANDS; resume $hash"
    done
    
    # Execute all resumes in a single connection
    docker exec $DELUGE_CONTAINER deluge-console "$RESUME_COMMANDS" > /dev/null 2>&1
    log "All torrents resumed"
fi

log "Script completed"
