append .mp3 at end of every file in a folder

Question

I have a folder with multiple files in it, and I want to append .mp3 extension at end of each file. is there any way to rename all these files with one command.?

Answer 1

Assuming the files don't already have any extension at all, then run this from the directory containing the files :-

for file in * ; do mv "$file" "$file".mp3; done 

If you want to be extra safe, do this instead :-

for file in * ; do cp "$file" "$file".mp3; done 

This will make copies of the files and add .mp3, instead of renaming them. You can always delete the originals afterwards.

Or if you want a graphical interface for mass renaming of files, then have a look at PyRenamer in the Software Centre.

and I want to append .mp3 extension at end of each file

short command

for f in *; do mv "$f" "$f.mp3"; done

Answer 3

Use the command rename. It allows perl regexpes. E.g.,

rename 's/(.*)/$1.mp3/' *

Will add ".mp3" to the end of any file or directory name in the directory.
