Linux mp3 server status script

[spankers]

How many of you have
(a)large mp3 collections and
(b)use a Linux box as a mp3 server?

I set up an old POS 300 MHz AMD K6 box as a mp3 server, Samba (Windows Network) server, and print server for my house. With Samba (http://us1.samba.org/samba/) running under Linux you can use networked mp3 players like the Audiotron (http://www.turtlebeach.com/site/products/audiotron/) that only work with Windows networking.

While I was ripping about 300 of my girlfriend's CD's I thought it would be nice to have the server create a current list of songs, calculate the size of the collection, calculate recent changes, report mp3 errors, and email me the results... so I wrote a not-so-beautiful shell script called by cron once a day. Here it is:
#!/bin/bash

cd /music
MP3SPACERAW=`du -s | tr -d "."`
MP3SPACEMB=`echo "scale=1; $MP3SPACERAW/1024" | bc`
MP3ARTISTS=`find /music -type d -maxdepth 1 | grep -c ""`
MP3DIRS=`find /music -type d -mindepth 2 | grep -c ""`
MP3SONGS=`find /music ! -type d -name "*.mp3" | grep -c ""`
MP3DIRAVG=`echo "scale=1; $MP3SPACEMB/$MP3DIRS" | bc`
MP3SONGAVG=`echo "scale=1; $MP3SPACEMB/$MP3SONGS" | bc`

DATE=`date "+%G%m%d-%R"`
FILEDATE=`date "+%g%m%d%k%M"`

cp /public/stats/mp3list.txt /public/stats/archive/mp3list-$FILEDATE.txt

printf "Summary information for the MP3 collection on server SATURN follows: \n" > /public/stats/summary.txt
printf "Artists/Top Level Directories: $MP3ARTISTS\t Albums: $MP3DIRS\t Songs: $MP3SONGS\n" >> /public/stats/summary.txt
printf "MP3 space used on partition: $MP3SPACEMB megabytes\n" >> /public/stats/summary.txt
printf "Average Album Size: $MP3DIRAVG megabytes\t Average Song Size: $MP3SONGAVG megabytes\n\n" >> /public/stats/summary.txt
printf "Recent changes (in diff format) and ID3 tag errors below.\n" >> /public/stats/summary.txt
printf "See attached ZIP file for latest song list.\n\n\n" >> /public/stats/summary.txt

find /music ! -type d -name "*.mp3" -exec mp3info -p "%-33a%-33l%02n %-30t\t[%r k]\n" {} \; \
2> /public/stats/mp3error.txt | sort > /public/stats/mp3list.txt.new

diff /public/stats/mp3list.txt /public/stats/mp3list.txt.new > /public/stats/mp3diff.txt
cat /public/stats/mp3diff.txt | cut -d "[" -f 1 > /public/stats/mp3updates.txt
cp /public/stats/mp3list.txt.new /public/stats/mp3list.txt

zip -jf /public/stats/mp3list /public/stats/mp3list.txt

cat /public/stats/summary.txt \
/public/stats/mp3updates.txt \
/public/stats/mp3error.txt | \
/usr/local/bin/nail \
-s "Saturn MP3 statistics for $DATE" \
-a /public/stats/mp3list.zip \
-r edward.xxxx@xxxx.net \
edward.xxxx@xxxx.net

sleep 10

/usr/local/sbin/nullmailer-send

It uses three programs that are not standard on most Linux boxes but are readily available on the net--
mp3info, a VERY flexible id3 tag tool
nail, a command line replacement for mail
nullmailer, a single shot SMTP program... I have not need for sendmail or exim.

The mail it sends:
Summary information for the MP3 collection on server SATURN follows:

Like I said, the script is not-so-beautiful but does the job and hopefully it provides some ideas for your mp3 server.

Oh... and here's a sample of the mp3 list the script generates.

Thanks! Like I said... it needs cleaning. I could add
PATH=
MP3PATH=
MP3STATPATH=

etc, ad nauseum....

The mp3 list again... the format gets screwed up when pasted to a web page... I use a monospace font in the editor I use:
