simonm, Just a nit While this works nearly 100% the same as the glob, it is not exactly the same. This is because some operating systems, nix for instance, support imbedded newlines in file names. I would recommend adding the s modifier, using something like (\d\|\D) in place of .*, or just annotating that it won't match files with imbbedded newlines. Cheers - L~R	[reply]

To continue with Limbic~Region's nit, file names can even have newlines at the end, in which case using `$` will cause the regex to match, for example, "onlythese1.txt\n". It will rarely if ever happen, but I tend to use `\z` to match the literal end of string, just in case. `my @files = grep { /^onlythese.*\.txt\z/s } readdir DIR;` [download] -- Mike -- `XML::Simpler does not require XML::Parser or a SAX parser.
