The <> operator has two purposes one as a IO handle readline function
the other as a file globber. You are using it in the second case. You
can read more in:
perldoc perlop
Specifically in the section on the <> operator and file globbing, which
is part of the "I/O Operators" subsection.
Essentially it recommends you use an explicit 'glob' in this case, so
something like:
unlink glob("$dir/*.bak");
Should do the trick. Don't forget to check for success, yada yada yada...
perldoc -f glob
