This is very good, especially making it into an alias. Two small
improvements perhaps:
First, check to see if a file with the new name doesn't already exist...
for if it does, it would be overwritten and lost. Changing "mv" to "mv
-i" would also notify the user of such events.
Secondly, unfortunately some filenames may contain whitespace. In such
a case the mv command will give unexpected results. So the arguments to
mv should be quoted.
