Renaming

Renaming using the file name's fields

Given files names such as ./{codeLang}-{word}-{speaker}-{id}.wav such as ./cmn-quan3-Can_Yue-LL12087.wav :

mkdir -p ./new                                # create dir
for file in ./cmn-*.wav;
do 
   key=$(basename "$file" | cut -d- -f2);     # using "-" as split, select field 2 : "quan3"
   cp "$file" ./new/cmn-"$key".wav;           # ./new/cmn-quan3.wav
done

Renaming using metadata

Dependencies

sudo apt-get install lame avconv                       # examine audio file's properties.

avconv's output

avconv -i ./cmn-jiāoliú.flac 2>&1                       # print out metadata of $file, for some formats only
