I think I'd do something like the following, on the command line with no scripts:-

OK. I've followed your instructions and I do indeed end up with a listfile comprising all the vcf entries.
But I don't understand why it works so can you explain it for me please? The problem I have is why am I running the echo line twice?
The 'for' executes everything between the 'do' and the 'done' for each .vcf file. The 'cat' does what you know, I put quotes round the file name to make it work with filenames that have embedded spaces. 'echo' just outputs what's after it, which in the above case is nothing except for CR/LF (end of line). I just did two echoes to give you two blank lines.
