I'm parsing some text file in following format: 
some text ()\xA1 file.txt

[download]
and generating html. $1 (below) sometimes gets trailing spaces, so I thought to strip'em off: 
(1)if ($line =~ /(.+)\s*\(\)\xA1\s*(.+\.txt)/) {
(2)  $file = $1;
(3)  $file =~ s/\s*$//;
(4)  print OUT "<a href=\"$2\">$file</a><br>\n"
}

[download]
But I'm getting error: "Use of uninitialized value in concatenation (.) or string at F:\downloads\lib.pl line 23, <IN> line 4." If I comment (3) everything works fine (except trailing spaces of course). It looks that $2 is somehow invalidated in line 3. TIA
