String manipulation & file I/O

I have a text file full of thousands of md5 hashes from around the interwebs but they are seperated with newlines.

I need to open the txt hash file, and write to another file but replacing every newline with nothing.

Possible languages: Perl, C++ or Visual Basic 6.

The proper way to deal with the OP is to question his motives.

Why would you want to remove newlines from the file? Either store the hashes in a text file with some sort of separator, or store them as pure binary. Not some kind of shit semi-text format.
