A Couple Of Scripts For Fast N Easy Music Files Conversion

A friend of mine wrote a couple of simple and fast scripts for conversion of m4a and ogg music files to mp3. Here is how you can use them.

1. we need a folder where we keep scripts and this folder should be set as a path in .bashrc .
For example the folder /home/username/bin and the appropriate line in .bashrc:

#Paths
PATH="/home/username/bin:${PATH}"

2. in that folder create two new files m4a2mp3.sh and ogg2mp3.sh

3. make the files executables, in terminal:

chmod +x /home/username/bin/*

4. edit the files with your favorite editor and add these lines:

#!/bin/sh
IFS="
"
while [ "$#" -gt "0" ]
do
****echo converting $1
****if file $1 | grep "MPEG v4" >/dev/null
****then 
********x=`echo $1 | sed 's/\(.*\.\)m4a/\1wav/'`
********y=`echo $1 | sed 's/\(.*\.\)m4a/\1mp3/'`
********if faad -o $x $1 >/dev/null 2>&1 && lame -h $x $y >/dev/null 2>&1
********then echo OK!
************rm $1
************rm $x
********else echo FAILED
********fi
****else echo 'NOT an MPEG v4 file'
****fi
****echo ''
****shift
done

for the m4a2mp3.sh file and

#!/bin/sh
IFS="
"
while [ "$#" -gt "0" ]
do
****echo converting $1
****if file $1 | grep "Ogg data" >/dev/null
****then 
********x=`echo $1 | sed 's/\(.*\.\)ogg/\1wav/'`
********y=`echo $1 | sed 's/\(.*\.\)ogg/\1mp3/'`
********if oggdec -o $x $1 >/dev/null 2>&1 && lame -h $x $y >/dev/null 2>&1
********then echo OK!
************rm $1
************rm $x
********else echo FAILED
********fi
****else echo 'NOT an OGG file'
****fi
****echo ''
****shift
done

for the ogg2mp3.sh file.

5. now you can use the scripts to convert your files.
for example if you have some ogg files in /home/username/music/ you can type:

ogg2mp3.sh /home/username/music/*

to convert all of them. if there are any non-ogg files you will be notified and if you want to change specific files only you must type the exact path or cleverly use wildcards.

Please let me know if there are any typos or mistakes and let me thank Herc who wrote the scripts. Nice job Hercules!
