Those changes won't work anyway as the code stands, because the OP code is opening the same file twice, once in read mode and once in write mode. That's a no-go.

The Tie::File module is a solution, a one-liner using in-line option is another. Else, opening another file for writing, making the necessary changes, and renaming the files is another option.

Then only should we worry about avoiding to change other lines, one way or another.
