Here's a script in perl. Use like this:

  ### Append .bak to all *.c files
  $ rename '$_ .= ".bak"' *.c

  ### Remove .bak from all *.c.bak files
  $ rename 's/\.bak$//' *.c.bak

  ### Convert to lowercase, but not for Makefile
  $ rename 'tr/A-Z/a-z/ unless /^Makefile/' *

#!/usr/bin/perl -w
# rename -- Larry's filename fixer

$op = shift or die "Usage: rename expr [files]\n";
chomp(@ARGV = <STDIN>) unless @ARGV;
for (@ARGV) {
    $was = $_;
    eval $op;
    die $@ if $@;
    rename($was,$_) unless $was eq $_;
}
