Something like this (with lots of assumptions):
Code:
$input=shift @ARGV;
$str="cupcakes";
$input{$_}+=1 for split //,$input;
$str{$_}+=1 for split //,$str;
$substitute=1;
for (keys %input) {if ($input{$_} > $str{$_}) {$substitute=0;last}}
$str =~ s/[$input]//g if ($substitute and !($str =~ s/$input//));
print "$str\n"

Some trial runs:
Code:
perl <scriptname> sake
cupc

perl <scriptname> cup
cakes

perl <scriptname> success
cupcakes
