How to do mv *.xyz *.abc in shell script??

[Alvaro Hui Kau]

Hi all experts out here!

Sorry for the stupid query, but I just don't know how to do
it. Once in a while I want to change the names of a bunch of
files from *.xyz to *.abc for example. I know there is a better
way to do this than doing it one by one but I just can't
find any way to do it. I know it can be done using shell script
but I don't know (yet) how to write them.

So, Is there anyone out there can help me on this problem?

Thanks in advance.
