The regex that Rob put forth does not match only files consisting entirely of periods, it matches any file that _starts_ with a period. On a *nix system, a file such as '.bash_profile' would be matched. Randal is correct. > > Your attack on Rob is uncalled-for. I don't believe that Mr. Schwartz attacked the OP; he merely stated that others should check Rob's responses for accuracy. In fact, given that this is a beginner's list, that probably holds true in other instances. And the fact the Randal has written a little on the subject of Perl, inclines me to trust his judgement. ry > > > > -- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > <http://learn.perl.org/> <http://learn.perl.org/first-response> > -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
