in thread Count similar characters in a row - only once

I have edited the script above as follows (below): it writes out a temporary file that I will use while running my second script. The second script will now take the temporary file which I will delete afterwards. Please critisize as it must be 100% accurate.

#!/usr/bin/perl use strict; use warnings; my $file = 'my_data_file.txt'; my %seen = (); { local @ARGV = ($file); #remove all previous re-organized files my $remove = "my.txt.tmp"; if (unlink($remove) == 1) { print "Existing \"$remove\" file was removed\n +"; } while(<>){ #now make a file for the ouput my $outputfile = "my.txt.tmp"; if (! open(POS, ">>$outputfile") ) { print "Cannot open file \"$outputfile\" to write to!!\n\n" +; exit; } $seen{$_}++; if($seen{$_} !~/-/g){ next if $seen{$_} > 1; print POS; } } } print "\n\nfinished processing file.\n";
