把当前目录下所有的ogg文件转换为mp3格式

first replace space with "_"

 

for x in * ; do mv "$x" `echo -n $x | tr " " "_"`; done

 

second: use sox convert ogg to mp3

 

 for x in *.ogg ; do sox $x `echo $x|awk -F . '{print $1 ".mp3"}'`; done

if you occured this error:  sox formats: no handler for file extension `mp3'

you can  convert ogg to wav first, then convert wav to mp3

 

for x in *.ogg ; do sox $x `echo $x|awk -F . '{print $1 ".wav"}'`; done

for x in *.wav ; do lame $x `echo $x|awk -F . '{print $1 ".mp3"}'`; done

 

If you didn't have lame command, you can install use

 

"yum -y install lame"  on fedora

 

 

 

Mp3 to ogg format

mpg321 input.mp3 -w - | oggenc -o output.ogg -

change all mp3 directory to ogg format in current

for x in *mp3; do mpg321 $x -w - | oggenc -o `echo $x |awk -F . '{print $1 ".ogg"}'` -; done

If you didn't have mpg321 command, you can install use

 

"sudo yum install mpg321"  on fedora
