linux - sending output to text file

hope this is an appropriate place to ask this. i have this: Code:for file in *.mp3; do sox $file -n stats > $file.txt 2>&1 | tail -1; donewhich makes a text file for each file examined in looping through a directory. how would i change this to write all of it to a single file, with a couple of lines between each set of stats?

thanks,
