Automatic Sync for MP3 Player.markdown

I wanted to do an automatic sync of a directory in my hard drive with 1 directory in my mp3 player (MSU Enabled) To launch an action on detecting it

I used the udev system by creating a rule under /etc/udev/rules.d/10-local.rules

SUBSYSTEMS=="scsi", ATTRS{model}=="MK3006GAL       ", SYMLINK+="DAP", MODE="0666"
SUBSYSTEMS=="scsi", ATTRS{model}=="MK3006GAL       ", ACTION=="add", RUN+="/usr/local/bin/music-sync %k"

The first line creates a symbolic link called DAP under /dev/ \ The second line runs a script I wrote to sync (and mount if required) the device

music-sync.bash

#!/bin/bash

# Author: Alejandro Endo

### Variables ###

LABEL="smartphone"; #directory inside /media where the device is mounted
DAP_DIR_TO_SYNC="/music/"; #dir in the device 
LOCAL_DIR_TO_SYNC="/mnt/Jukebox/"; #dir in the local computer (should end in '/')"
LOG_FILE="/tmp/rsync.log"

### Code ###

print () {
    if [ "$broad" = 1 ];then
	echo -e "$1" | wall
#	echo -e $1
   else
	#echo -e \[`date +"%F %r"`\] "$1"
	echo -e "$1"
    fi
}

usage () {
    print "Usage: $0 [--dry-run] [--broadcast] <device under /dev/>"
    exit 1 
}

output=""

#Parse arguments

until [ -z "$2" ]  # Until all parameters used up . . .
do
	case "$1" in
	--broadcast)
		broad=1;;
	--dry-run)
		dryRun="--dry-run";;
	-*) 
		usage;;
	esac
  shift
done

DEVICE="$1"
if [ "$DEVICE" = "" ]; then 
	print "Missing dev parameter"
	usage
fi

if [ ! -b "/dev/$DEVICE" ]; then
	print "Device not found: $DEVICE\n"
	usage
fi

#Mount the device

print "Determining if we need to mount...\n"

count=`ls /media/${LABEL} | wc -l`

if [ "$count" -ne 0 ]; then
    #exists already
    print "Device mounted already\n"
else 
    print "Mounting: $DEVICE\n"
    pmount --type vfat --umask 022 --sync "$DEVICE" "$LABEL"
    count=`ls /media/${LABEL} | wc -l`
    if [ "$count" -eq 0 ]; then
	print "Mount Failed\n"
	exit 1
    fi
fi

#Autosync

print "\nSync...\n"
rsync $dryRun --delete --verbose --times --recursive --stats --human-readable --progress --log-file="$LOG_FILE" --modify-window=3601 "$LOCAL_DIR_TO_SYNC" "/media/${LABEL}${DAP_DIR_TO_SYNC}" #| tee -a "$LOG_FILE"

#echo -e  "$?\n$output\n" >> "$LOG_FILE"
#echo -e `ls /media/${LABEL}` >> "$LOG_FILE"
