Your code has some small inconsistencies: 
    my $tempname = $basedir . '/output/file.txt';
You might use string interpolation here, like: "${basedir}/output/file.txt"; 
    open (OUTHANDLE, ">$tempname") or die;
Better use indirect filehandle and let it tell yourself *why* it died,
like: open my $oh1, '>', $tempname or die "$!"; 
    open (OUTHANDLE, ">$basedir . /output/file.txt") or die ;
This might be a typo, but you used string interpolation ("..") *AND*
tried "string concatenation" within the interpolated string. Which won't
do what you intended.

better use something like: 
 my $basedir = 'results';
 my $tempname = "${basedir}/output/file.txt";
 open my $oh1, '>', $tempname or die "$!";
 open my $oh2, '>', "${basedir}/output/file.txt" or die "$!";

instead. The ${name} thingy would allow interpolation *within* words
like "${basedir}andmore", otherwise a variable $basedirandmore would
be searched but not be found.
