Command to batch move filetypes to directories with the same name (linux)

[ChiefMedicalOfficer]

I had to use this command for the first time the other day as I had 20 single mp3 files that were all individual audiobooks under a parent directory of 'author'.

I used the following command to move all those files based on file type to directories with the same name as the file. Maybe it could come in handy.

cd /location/of/files

for file in *.mp3; do mkdir -- "${file%.mp3}"; mv -- "$file" "${file%.mp3}"; done
