you probably want a regexp more like 
/^[_a-zA-Z][^.]{1,7}\.txt$/

This matches an underscore or letter (the {1} is unnecessary, char classes always match one char only, which is why you need modifiers like * or + to make it do something different)

Then you can do 

while(<READFILE>) { 
  # something here  
}

[download]
which will go through the file line by line putting the data in $_
I would read up on chomp and split and regular expressions on how to work with the data in the file.

P.S. put <code> tags around your code to make it display properly in a post.
