how many mp3s?

linuxhippy · 11-14-2006, 05:05 AM

I want to see how many mp3s I have on my Slackware 11 server. It doesn't have X installed. I've been using df -h for years and that gives an overall view of your mounted partition space. Could I use it to tell me how many mp3 files are on /mnt/mp3?

It can take longer if you have lots of them, but it should do the trick:
find /path/where/to/search -type f -iname "*mp3" | wc -l

EDIT: I just noticed that this probably is not what you are looking for. I interpreted "how many" as the number of mp3s rather than the space they are taking on your harddisk. Should have read better :-|

You can cd to /mnt/mp3 and issue "du -h", the last number will give you the overall size of the folder. This won't give you the size of your mp3 files only, if you have other files like cover images etc. saved there too. A quick hack I created out of curiosity:

Code:

find /mnt/mp3  -type f -iname "*mp3" -exec ls -al "{}" \; > ~/mp3-space
cat ~/mp3-test | cut -d" " -f5 > ~/mp3-space2 
while read individual; do total=$(($total+$individual)); done < ~/mp3-space2; echo All mp3 files take $total bytes on /mnt/mp3
rm ~/mp3-space ~/mp3-space2

I could bet someone will give you a better script after (s)he has seen my [ironical] simple and elegant [/ironical] script.

Shoudln't a

Code:

find /mnt/mp3 -type f -iname "*mp3" | du -hc

tell the size of all mp3 files in /mnt/mp3?

Edit: Ah but the file sizes aren't listed with find... need to use ls for that I think...
Some more adept at bash can solve this properly

You could use xargs here

Code:

find /mnt/mp3 -type f -iname "*mp3" -print0 | xargs -0 du -hc

I don't want the size of the mp3 files. I'd like to know how many mp3 files I have...should be thousands of files.

This worked well-thanks!

Instead of using find for this many files, could I use locate or slocate for speed?

slakmagik · 11-14-2006, 12:36 PM

Yes. The locate man page describes the '-r' and '-i' switches. But given a sufficiently large database and a sufficiently small and targeted audio file hierarchy, it's possible locate could be slower. Not likely, but just saying...

I just experimented with a couple files (I'm not at my mp3 server), but this seems to work quick:

slocate *.mp3 | wc -l

How could I refine that to only search in /mnt/mp3? Is that -r or -i?

linuxhippy · 11-14-2006, 01:52 PM

This works on a couple files and is quick:

slocate -d=/mnt/mp3 *.mp3 | wc -l

I wound up using the find command (it was quick on my 200 MHz CPU) and got 5722 with:

find /mnt/mp3 -type f -iname "*.mp3" | wc

Thanks for all the help!!
