Well, you would have to lock the file using the flock call of Tie::File. It will invalidate the cache, so it's not efficient. And then it will only work if the writers use flock as well (which not every writer actually needs to do; if all writers open the file for append, and writes are smaller than the buffer size (typically 8k), data won't be garbled).

But I fail to see the point of Tie::File in the first place. Considering the OP just wants to move files, and doesn't express any wish to actually remove data, what's the point of reading in the file in the first place?
