One of several ways: 

printf "There %s $_ piece%s of pizza left\n",
    $_==1 ? ('is','') : ('are','s') 
    for 0 .. 2;;
There are 0 pieces of pizza left
There is 1 piece of pizza left
There are 2 pieces of pizza left

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
