Code like this is often simpler if you use the Unix filter model and let the operating system take care of opening all the files.
#!/usr/bin/env perl

print @lines;
That's one way of using up a lot of memory.
If this is in a file called 'join', you can run it like this:
$ ./join < input.txt > output.txt
Use the tools you've already got as part of the OS install: /usr/bin/tr -d '\012' < input.txt > output.txt
