Answer 1

I misread the question, it’s about batch renaming
You can use the
ls和管道和renamecommand
for batch renaming Similar to the following batch delete command.

Answer 2

perl-rename 's/prefix/replacement/'

Answer 3

for i in $( seq 1 10 );do
mv $i-music$i.mp3 music$i,mp3;
done

Answer 4

rename 's/^.*-\(.*\.mp3\)//' *.mp3

This will delete the aaa- in the name aaa-bbb.mp3;
