mv won't allow this because wildcard expansion (called globbing in
*nix) is done by the shell, not by the tool itself.
However, many Linux systems have a little tool which comes with perl
called 'rename'. rename accepts any perl expression which modifies $_ to
apply to each filename it gets, so thus you would do:
rename 's/\.txt$/\.bak/' *.txt
You can also do much more powerfull things, like renaming such that case
is changed to all lower-case, and many other useful things. See rename(1).
