This is a common task, try a module like File::Temp. If you have perl 5.6.1 or newer, it is already installed. In your case, use UNLINK => 1 to automatically remove the temp. file after program execution. There are more options that let you fine-tune the filename format/suffix, the directory and so on. 

use strict;
use warnings;
use File::Temp qw(tempfile);

#-- UNLINK => 1: removes the tempfile when program finishes
#   perldoc File::Temp - shows more usage options
my ($fh, $filename) = tempfile( UNLINK => 1);

#-- that's it - now display filename...
print "Filenme:  $filename\n";

#-- or use filehandle... (here: no open()/close() required!)
print $fh "lalala\n";

#-- here: file is removed automatically on program exit
