Bash make directory based on filename and add .itmsp

I need my script to wrap up files with specific extensions and XML into a directory that is named as per the files. In addition the directory needs to be renamed filename+.itmsp. At the moment the script creates a directory based on the filename but I am not sure how to add the .itmsp to the directory name.

#!/bin/bash
path='/Volumes/Drive/TEST'    
cd $path

for FILE in开发者_如何学编程 `ls | egrep "xml|mov|mpeg|mpg"`
do
  DIR=`echo $FILE | cut -d '.' -f 1`
  mkdir -p $DIR
  mv $FILE $DIR
done

Since this is bash:

cd /Volumes/Drive/TEST
for FILE in *.{xml,mov,mpeg,mpg}
do
  # remove the last dot and subsequent chars, then add new ext
  DIR="${FILE%.*}.itmsp"
  mkdir -p "$DIR"
  mv "$FILE" "$DIR"
done

Just append .itmsp to $DIR like "$DIR.itmsp".
