Renaming multiple files in single command in Linux

In Linux renaming a file or two is very simple with 'mv' but how about hundred or thousand in one shot?

Here I have list of files:

doc1.TXT.read
doc2.TXT.read
doc3.TXT.read
doc4.TXT.read
doc5.TXT.read
doc6.TXT.read
doc7.TXT.read
doc8.TXT.read

Now, I want to rename it to doc1.txt, doc2.txt so on and so forth i.e changing the capital .TXT to lower case .txt and remove the .read extension

for f in *.TXT.read ; do mv -i "$f" "${f%%.*}.txt" ; done

The result will be:

doc1.txt
doc2.txt
doc3.txt
doc4.txt
doc5.txt
doc6.txt
doc7.txt
doc8.txt

And there you have it !!
