Re: Counting only certain files...

I would suggest passing readir to a grep.
I used it in one of my scripts like so,

  @Files = grep {not /^(\.\.?|list\.txt)$/} readdir(DIR);
[download]

This returned all files except '.' and '..' and a file named 'list.txt'.

I think using grep() or glob() in this case is a total overkill. You are not going to use filenames afterwards, so there is no need to allocate all that memory just to throw away the result. `my $total = 0; opendir DIR, "$config{'basepath'}$key" or &oops("Category directory $k +ey could not be opened."); while ($_ = readdir DIR){$total++ if -f and /\d/o } closedir DIR;` [download] --perlplexer	[reply] [d/l]

I went with this... `my $numfiles = 0; opendir DIR, "$config{'basepath'}$key" or &oops("Category +directory $key could not be opened."); readdir DIR;readdir DIR; while ($_ = readdir DIR){$numfiles++ if /\d.dat/o } closedir DIR;` [download] My files actually end with .dat, therefore I added the extension... I want to thank you all for your help... GOD I love this site... (no pun intended!) _______SysAdm	[reply] [d/l]
