Let's break up this line split (/\s+/) # this is actually splitting the contents of $_ using \s+ as the delimiter The bigger expression (split (/\s+/), $str_line) just returns the contents of $str_line. Read through the documents on the comma operator (perldoc perlop, sub-section Comma Operator) What you are getting is the content of $str_line as such. This is what you want my $user = (split (/\s+/, $str_line))[0]; You might also want to consider turning warnings on and add use strict to your code > > > > Any help would be appreciated > > Thanks in advance, > Melissa > > ------------------------------------------------------------------------------ > This message and any attachment is confidential and may be privileged or otherwise >protected from disclosure.
