Move Files to a folder with the same name

#!/bin/bash


#This script allows files with the same name and different extension to be sorted in a folder with name, same as the file name. This is useful, when I download my Linux Journal magazines in different file formats and have to import them into Calibre

books="*.*"

for f in ${books}
do
    dirname=$(echo $f | cut -f1 -d'.' )
     echo $dirname
     mkdir -p $dirname
     mv $f $dirname
done
