It sounds like you know the column widths, and looks like the first column will be all whitespace unless you are starting a new record.
while (my $textline=<DATAFILE>)
{
if ( substr($textline,0,9) =~ /\S/)
{
#New record detected - Print out old one, and prep for new
printf ("%s%s%s%s\n",$nodename,
$filename, $backupdate, $pathname);
$nodename = substr($textline, 0, 9);
$filename = '';
$pathname = '';
$backupdate = '';
}
$filename .= substr($textline, 10,19);
$pathname .= substr($textline, 20,29);
$backupdate .= substr($textline, 30);
}
