You cannot use chomp to erase characters you have already printed. For the logic of separating items by commas, Perl has the convenient join function. All you need to do is get the items you want to print into a list to pass to join. grep is a good way to do this: 
my @dir = readdir DIR;

my @to_print = grep { -r $_ && -w $_ && -x $_ && /^[a-zA-Z]/ } @dir;

print join "," => @to_print;
