A couple of things, you don't need to quote variables in perl as you might in the shell and you might want to check for the existence of the file. Here's my take on the exercise 
{
  print "Enter filename: ";
  chomp($f = <STDIN>);
  print "invalid file" and redo
    unless -f $f and -r $f;
}
open(f) and print reverse <f>;

A little idiomatic admittedly, but that's fine by me :)
