Thanks very much.

Well, I checked out the mini script, and it isn't actually working.

Here's what I found. First, it doesn't look like double-quotes matter. You still get file not found errors. Only by placing the * outside the quotes, or double-quotes in this case, are the files recognized.

As well, it seems that instead of appending one file to the next, somehow, at least the way I tried it, the output file was being rm before the next append, so each file was simply appending to a now non-existing file.

As I understand it, wherever you say "my file" that means the filename of the output file, correct? So then the only place we're referring to the input files are the line:

Code:
for file in 'my file.'*

Is that right?
