That's where the \s* instead of \s+ comes in. \s+ assumes that there will be at least one character, but if you chomp and the only character on the line was a \n, then it will fail because there are no characters on the line anymore.

Hmm. I'm not sure. Maybe if you post a little more of your code? $_ =~ /^\s*$/ should match any line where there are only whitespace characters or no characters at all. -----Original Message----- From: Allison Ogle [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 04, 2002 1:35 PM To: Timothy Johnson; Nikola Janceski; a a Subject: RE: Filehandle = blank line??? I did mean $word=<FILEHANDLE>. It was just written wrong in the e-mail. Sorry about that. -----Original Message----- From: Timothy Johnson [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 04, 2002 4:25 PM To: 'Allison Ogle'; Nikola Janceski; a a Subject: RE: Filehandle = blank line??? Ok, I guess I misunderstood the question, and maybe I still do. As I understand it, what you are saying with '<FILEHANDLE> = $word;' is "Store the value of $word into the default variable that results from reading the next line from FILEHANDLE", or something like that. Did you mean '$word = <FILEHANDLE>;'? -----Original Message----- From: Allison Ogle [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 04, 2002 1:27 PM To: Nikola Janceski; a a Subject: RE: Filehandle = blank line??? I will actually be storing the filehandle as a variable and then comparing it. Something like <FILEHANDLE>= $word; chomp $word; if ($word eq 'blank line') { ... } how would I use your suggestion in this case? if ($word=~ /^\s*$/) doesn't seem to work. -----Original Message----- From: Nikola Janceski [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 04, 2002 3:53 PM To: 'Timothy Johnson'; 'Michael Stearman'; [EMAIL PROTECTED] Subject: RE: Filehandle = blank line??? he might have chomp it... safer would be: if($_ =~ /^\s*$/){ } shorter would be: if(/^\s*$/){ } > -----Original Message----- > From: Timothy Johnson [mailto:[EMAIL PROTECTED]] > Sent: Thursday, April 04, 2002 3:42 PM > To: 'Michael Stearman'; [EMAIL PROTECTED] > Subject: RE: Filehandle = blank line??? > > > > Maybe if($_ =~ /^\s+$/){ > do something... > } > > -----Original Message----- > From: Michael Stearman [mailto:[EMAIL PROTECTED]] > Sent: Thursday, April 04, 2002 12:46 PM > To: [EMAIL PROTECTED] > Subject: Filehandle = blank line??? > > > Hello all, > > I am stepping through an input file using the filehandle and > I need to do an > > if statement which recognizes whether the filehandle is a > blank line.
