OK so hears is the problem i have about 20 gigs of music all on m4a (itunes don't ask why) and i want to convert them all to mp3 now i have established that by using the following command

for i in *.m4a
do
base=`basename "$i" .m4a`
faad -o - "$i" | lame -h -b 192 - "$base.mp3"
done ; rm *m4a

that will convert every m4a in that directory to mp3 now is there a way to alter that command so that it will search through the directory's and the directory's within those directory's and convert all the tracks contained within them.

Hi!
don't

Code:

for i in */*.m4a

and

Code:

for i in */*/*.m4a

work?

Regards

hi it almost works it finds and converts the files ok but it converts them all to the directory i issue the command from and not to the directorys they came from. thanks for your help have you got any other ideas ?

Hi!
yes you're right.
Take a look at "basename --help". It looks like it removes any directory name.
I think you should make a list of directories, visit them one after the other and once there process the files inside.
This command should be helpful:

Code:

find -type d

typing just it shows you all the directories inside the PWD and down.
So this

Code:

for i in `find -type d`

do

cd $i

for j in *.m4a

do 

base=`basename "$j" .m4a`

faad -o - "$i" | lame -h -b 192 - "$base.mp3"

rm *.m4a

done

cd -

done

should work.

Regards

still not working :( ive tried playing with this a little bit but got no where. it does convert the files to some sort of mp3 but there not readable and there only a few KB's. for some reason it asks for permission to remove the orginal m4a's this time where as it didnt before hears the code

Code:

chris@home2-linux:~/Desktop$ for i in Alter_Bridge/One_Day_Remains/

> do

> cd $i

> for j in *.m4a

> do 

> base=`basename "$j" .m4a`

> faad -o - "$i" | lame -h -b 192 - "$base.mp3"

> rm *.m4a

> done

> cd -

> done
